In most cities and counties, permits will be required for the installation of electrical circuits or the construction of exterior surfaces (decks and
gazebos). In addition, some communities have adopted residential barrier codes which may require fencing and/or self-closing gates on the property
to prevent unsupervised access to a pool (or spa) by children under 5 years of age. Your CALDERA spa is equipped with a locking cover that meets
the ASTM F1346-91 Standard for Safety Covers, and as a result, is usually exempt from most barrier requirements. As a general practice, your local
Building Department will inform you of any applicable barrier requirements at the time a permit is obtained for the installation of an electrical circuit.
Your CALDERA dealer can provide information on which permits may be required.
WELCOME
Watkins Wellness congratulates you on your decision to enjoy the finest spa available. Welcome to the
growing family of Caldera® spa owners.

IMPORTANT SAFETY
INSTRUCTIONS
(READ AND FOLLOW ALL
INSTRUCTIONS)
AVOIDING THE RISK TO CHILDREN
DANGER - RISK OF CHILD DROWNING
Extreme caution must be exercised to prevent unauthorized access
by children. To avoid accidents, ensure that children cannot use a spa
unless they are supervised at all times.
WARNING
To reduce the risk of injury, do not permit children to use this spa unless
they are closely supervised at all times.
To reduce the risk of injury, do not permit children to use this spa
unless they are closely supervised at all times.
To reduce the risk of injury, lower water temperatures are
recommended for young children. Children are especially sensitive to
hot water.
The device should not be used by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they receive supervision or training.
DO:
Make sure you always lock the child resistant locks after using the
spa for your children’s safety. Every CALDERA spa is equipped with
a locking cover that meets the ASTM F1346-91 Standard for Safety
Covers.
Test the water temperature with your hand before allowing children to
enter the spa to be sure that it’s comfortable. Children are especially
sensitive to hot water.
Remind children that wet surfaces can be very slippery. Make sure
that children are careful when entering or exiting the spa.
DON'T:
Allow children to climb onto the spa cover.
Allow children to have unsupervised access to the spa.
AVOIDING THE RISK OF ELECTROCUTION
DANGER - RISK OF ELECTROCUTION
Connect only to a grounded source.
Do not bury the power cord. A buried power cord may result in death,
or serious personal injury due to electrocution if direct burial-type
cable is not used, or if improper digging occurs.
A ground terminal (pressure wire connector) is provided on the
control box inside the unit to permit connection of a minimum
10 mm² solid copper bonding conductor between this point and any
metal equipment, metal water pipe, metal enclosures of electrical
equipment, or conduit within 1.5 m (5') of the unit as needed to
comply with local requirements.
Do not operate the main audio/video button controls on any external
media devices such as a CD or DVD player while inside in the spa.
Operation of integrated audio/video equipment through the spa
control panel or wireless remote is permitted and acceptable.
Do not connect any auxiliary components (for example, cable
additional speakers, headphones, additional audio components) to
the audio system unless approved by Watkins Wellness .
Do not self service audio component by opening spa door as this
may expose dangerous voltage or other risk of injury. Refer all
servicing to qualified service personnel.
Do not attach an external antennae to a spa audio system unless
installed by a licensed electrician in accordance with National Electric
Code.
WARNING
To reduce the risk of electrical shock, replace a damaged cord
immediately. Failure to do so may result in death or serious personal
injury due to electrocution.
In order to avoid a hazard due to inadvertent resetting of the thermal
cut-out, this appliance must not be supplied through an external
switching device, such as a timer, or connected to a circuit that is
regularly switched on and off by the utility.
Always test the residual current device (RCD) before each use of the
spa. If the RCD does not perform properly, a ground current is flowing
indication the possibility of electric shock. Disconnect power to the spa
until the fault has been identified and corrected.
NOTE: Failure to wait 30 seconds before resetting the RCD may
cause the spa’s Power Indicator (on the control panel) to blink. If this
occurs, repeat the RCD test procedure.
Your spa must be supplied by a residual current device with a tripping
rating not exceeding 30 mA in an electrical subpanel.
DANGER - RISK OF ELECTRICAL SHOCK
Install spa at least 1.5 m (5') from all metal surfaces. A spa may be
installed within 1.5 m (5') of a metal surface if each metal surface is
permanently connected by a minimum 10 mm2 solid copper conductor
attached to the wire ground connector on the terminal box that is
provided for this purpose.
Do not permit any electrical appliances, such as a light, telephone,
radio, or television within 1.5 m (5') of a spa. Failure to maintain a
safe distance may result in death, or serious personal injury due to
electrocution, if the appliance should fall into the spa.
Install your spa in such a way that drainage is away from the electrical
compartment and from all electrical components.
DO:
Be sure your spa is connected to the power supply correctly - use a
licensed electrical contractor.
Disconnect the spa from the power supply before draining the spa or
servicing the electrical components.
Test the Ground Fault Circuit Interrupter(s) before each use.
Replace audio components only with identical components (if your spa
is equipped with an audio component).
Page 2 Safety Information
DON'T:
Use the spa with the equipment compartment door removed.
Place electrical appliances within 1.5 m (5') of the spa.
Use an extension cord to connect the spa to its power source. The
cord may not be properly grounded and the connection is a shock
hazard. An extension cord may cause a voltage drop, which will cause
overheating of the jet pump motor and motor damage.
Attempt to open the electrical control box. There are no user serviceable
parts inside.
RISKS TO AVOID
DANGER - RISK OF INJURY
To reduce the risk of injury to persons, DO NOT remove suction fittings
(filter standpipes) located in the filter compartment.
The suction fittings in the spa are sized to match the specific water
flow created by the pump. Never replace a suction fitting with one
rated less than the flow rate marked on the original suction fitting.
There is a danger of slipping and falling. Remember that wet surfaces
can be very slippery. Take care when entering or exiting the spa.
Never operate spa if the suction fittings are broken or missing.
People with infectious diseases should not use the spa.
Keep any loose articles of clothing, long hair, or hanging jewelry away
from rotating jets or other moving components.
INCREASED SIDE EFFECTS OF MEDICATION
The use of drugs, alcohol may cause unconsciousness with the
possibility of drowning.
Persons using medications should consult a physician before using
a spa; some medication may cause a user to become drowsy, while
other medication may affect heart rate, blood pressure, and circulation.
Persons taking medications which induce drowsiness, such as
tranquilizers, antihistamines, or anticoagulants should not use the spa.
HEALTH PROBLEMS AFFECTED BY SPA USE
Pregnant women should consult a physician before using spa.
Persons suffering from obesity, or with a medical history of heart
disease, low or high blood pressure, circulatory system problems, or
diabetes should consult a physician before using spa.
UNCLEAN WATER
Keep the water clean and sanitized with correct chemical care. The
recommended levels for your CALDERA spa are:
Free Available Chlorine:
1 - 5 ppm
Total Alkalinity:
40 - 120 ppm
Water pH:
7.2 - 7.8
Calcium Hardness:
Standard 75 - 150 ppm
Salt System 25 - 75 ppm
Refer to Water Quality and Maintenance section for complete
instructions.
IMPORTANT: Turn on the jet pump for a least ten minutes after adding
ANY spa water chemicals into the filter compartment.
Clean the filter cartridges monthly to remove debris and mineral buildup
which may affect the performance of the hydromassage jets, limit the
flow, or trip the high limit thermostat, which will turn off the entire spa.
AVOIDING THE RISK OF HYPERTHERMIA
Prolonged immersion in hot water can result in HYPERTHERMIA, a
dangerous condition which occurs when the internal temperature of
the body reaches a level above normal 37°C (98.6°F). The symptoms
of hyperthermia include unawareness of impending hazard, failure to
perceive heat, failure to recognize the need to exit the spa, physical
inability to exit the spa, fetal damage in pregnant women, and
unconsciousness resulting in a danger of drowning.
WARNING
The use of alcohol, drugs, or medication can greatly increase the risk of
fatal hyperthermia in hot tubs and spas.
TO REDUCE THE RISK OF INJURY
The water in the spa should never exceed 40°C (104°F). Water
temperatures between 36°C and 40°C (97°F and 104°F) are
considered safe for a healthy adult. Lower water temperatures are
recommended for extended use (exceeding ten minutes) and for
young children. Extended use can cause hyperthermia.
Pregnant or possibly pregnant women should limit spa water
temperatures to 36°C (100°F). Failure to do so may result in
permanent injury to your baby.
Do not use spa immediately following strenuous exercise.
AVOIDING THE RISK OF SKIN BURNS
To reduce the risk of injury, before entering a spa the user should
measure the water temperature with an accurate thermometer.
Test the water with your hand before entering the spa to be sure it’s
comfortable.
SAFETY SIGN
Each CALDERA spa is shipped with a SAFETY SIGN in the owner’s
package. The sign, which is required as a condition of Product Listing,
should be permanently installed where it is visible to the users of the
spa. To obtain additional SAFETY SIGNS, contact your CALDERA
dealer and request Part #70798.

Safety Information
SAVE THESE INSTRUCTIONS
IMPORTANT
SPA INSTRUCTIONS
The following contains important spa information, and we strongly
encourage you to read and apply them.
DO:
Use and lock the vinyl cover when the spa is not in use, whether it is
empty or full.
Follow the Spa Care and Maintenance recommendations stated in this
manual.
Use only approved accessories and recommended spa chemicals and
cleaners.
DON'T:
Leave the CALDERA spa exposed to the sun without water or the
cover in place. Exposure to direct sunlight can cause solar distress of
the shell material.
Roll or slide the spa on its side. This will damage the siding.
Lift or drag the vinyl cover by using the cover lock straps; always lift or
carry the cover by using the handles.
Attempt to open the electrical control box. There are no user
serviceable parts inside. Opening of the control box by the spa owner
will void the warranty. If you have an operational problem, carefully go
through the steps outlined in the Troubleshooting section. If you are not
able to resolve the problem, contact your authorized CALDERA dealer.
Many problems can easily be diagnosed over the telephone by an
Authorized Service Technician.
SPA SHELL
Your CALDERA spa has an acrylic shell. Stains and dirt generally will
not adhere to your spa’s surface. A soft rag should easily remove most
dirt. Most household chemicals are harmful to your spa’s shell (see
below for detailed information on cleaning agents). Always rinse off any
spa shell cleaning agent with fresh water.
IMPORTANT:
1. The following products are the ONLY approved cleaning agents for
your CALDERA spa shell: plain water, CALDERA FreshWater® Spa
Shine, Brillianize® or Soft Scrub®. The use of alcohol or any other
household cleaner other than those listed to clean the spa shell
surface is NOT recommended. DO NOT use any cleaning products
containing abrasives or solvents since they may damage the shell
surface, specifically: Simple Green®, Windex® or Spa Mitt. NEVER
USE HARSH CHEMICALS! Damage to the shell by use of harsh
chemicals is not covered under the warranty. Always rinse off any
spa shell cleaning agent with fresh water.
2. Iron and copper in the water can stain the spa shell if allowed to go
unchecked. Ask your CALDERA dealer about a Stain and Scale
Inhibitor to use if your spa has a high concentration of dissolved
minerals. (Watkins recommends FRESHWATER Stain & Scale
Defense.)
3. Keep all cleaners out of the reach of children and use care when
applying.

Getting Started
The illustrated spa may look different than
yours.
HYDRO JETS
ADAPTAFLO Jets - These jets allow you to redirect the jet stream by
changing the position of the nozzle.
ADAPTASSAGE Jets - These jets provide a rotating massage pattern.
The face plates in the ADAPTAFLO jets and the ADAPTASSAGE jets
are interchangeable. To remove a ADAPTASSAGE face plate, turn it
counter-clockwise until it stops turning. Turn the face once more until
you hear a clicking noise, push it in, and then pull it straight off. Install
the face plate by snapping it into place. Additional ADAPTASSAGE
dual-port nozzles are available from your CALDERA dealer.
Both the ADAPTAFLO and ADAPTASSAGE jets allow you to regulate
the force of the massage. Rotate the fascia ring to reduce or increase
the force. Notice that turning off the flow to some jets increases the
flow to the other jets. To avoid damage to your spa’s plumbing and
components, do not turn off more than half of these jets at the same
time.
EURO DIRECTIONAL - The Euro Directional jets, with eyeball nozzles,
deliver a direct, more focused massage.
EURO-PULSE Jets - The EURO-PULSE jets feature a special insert
that creates a soft, pulsating, rotary massage.
NOTE: Please do not attempt to rotate the jet face on either the Euro
Directional, or EURO-PULSE as these jets do not regulate the force of
the massage.
VERSASSAGE Jets - These jets may be adjusted to provide either a
stationary, direct stream or, by positioning the nozzle to one side or the
other, a rotating jet stream.
The VERSASSAGE jets allow you to regulate the force of the massage.
Rotate the fascia ring counter-clockwise to reduce the force, or
clockwise to increase the force. Notice that turning off the flow to some
jets increases the flow to the other jets. To avoid damage to your spa’s
plumbing and components, do not turn off more than half of these jets at
the same time. For cleaning instructions, see the VERSASSAGE Jets
Maintenance section.
EUPHORIA Jet
(MAKENA, SALINA, SEYCHELLES & REUNION spas only) - The
EUPHORIA jet provides a deep powerful, penetrating massage to your
tired feet, calves, knees and thighs.
DIVERTER VALVES
The diverter valves on your spa allow you to direct the flow of water
from the pumps to various combinations of jets. The functions of these
diverter valves can best be learned by experimentation as follows:
Set all air controls to the
“ON” position.
Turn on both pumps.
Turn the handle on
each diverter valve
and see which
groups of jets are
affected. (Note that
you can adjust the
diverter valves to any
position between the two
possible extremes to achieve the jet pressure that feels best to you.)
IMPORTANT: Your spa is not designed to provide full power to all jets
when the diverter valves are in the “mid” position. However, with the
diverter valve in this position, you may increase the power to selected
jets by rotating the face of the ADAPTAFLO and ADAPTASSAGE jets
to close the ones that are not in use.
TIP: Turn both pumps on and place the diverter valves to the “Mid-
Position”. Then experiment with each of the air controls to see their
effect.

WATERFALL VALVE
The SALINA, MAKENA, MARTINIQUE,
SEYCHELLES & REUNION spas are equipped
with a cascading waterfall feature. It is activated by
pressing the "JETS" button and turning the valve
located on the front interior wall counterclockwise.
The flow is regulated by turning the waterfall valve
to the desired position.
AIR CONTROLS
Each jet system has its own air
control. These allow you to change
the power of the jets by regulating the
amount of air that is mixed with the
water coming out of the jets.
QUICK START-UP INSTRUCTIONS
BEFORE YOU FILL YOUR SPA
Make sure your spa has been properly installed per all local codes, this
includes the location of the spa, the foundation of the spa as well as
the electrical installation of the spa. Installation instructions in the form
of a Pre-Delivery Instruction booklet can be obtained from either your
CALDERA dealer or online.
DO:
Know which water treatment system you will be using and make sure
you have necessary chemicals available. Read all of the instructions
that come with the system.
Have FRESHWATER 5-way Test Strips Available.
Have FRESHWATER Salt Test Strips Available if using the Salt system.
Have pH/Alkalinity Up & Down available.
Know the "Hardness" of your water, contact your dealer to help you
with this information. See Water Quality and Maintenance for more
information.
IMPORTANT: The spa can be filled with “softened” water as long as
the calcium hardness parameters (pg. 2) are maintained.
Purchase the Clean Screen pre-filter to remove unwanted
contaminants from the tap water. This is recommended, not required.
DON'T:
Power up the spa until it has been filled with water! Power to the
spa automatically activates critical components within the spa, such
as controls, heater, circulation pump, and other systems. If power
is supplied to these components prior to the spa being filled, the
components will be damaged, and this may result in a non-warranty
component failure.
Fill the spa with hot water or cold water with the cold water temperature
below 10º C (50º F)! Tripping of the high-limit thermostat may result
causing your spa to stop functioning.
START-UP
Your CALDERA spa has been thoroughly tested during the
manufacturing process to ensure reliability and long-term customer
satisfaction. A small amount of water may have remained in the
plumbing after testing and, as a result, may have spotted the spa shell
or the spa siding prior to delivery. Before filling the spa, wipe the spa
shell clean with a soft rag. The following instructions must be read and
followed exactly to ensure a successful start-up or refill.
CAUTIONS
Do NOT fill the spa with hot water, as tripping of the high-limit
thermostat may result.
DO NOT CONNECT POWER TO AN EMPTY SPA. Power to the
spa automatically activates critical components within the spa, such
as controls, heater, and other systems. If power is supplied to these
components prior to the spa being filled, the components will be
damaged, and this may result in a non-warranty component failure.
DO NOT use your spa after filling until all of the steps listed below are
completed.
DO NOT add chlorine if treating your spa with polyhexamethylene
biguanide (Biguanide, PHMB, eg. BaquaSpa
®) sanitizer.
Before filling your spa for the first time, remove the equipment
compartment door and check to ensure that the unions on either side
of the pump(s) and heater are hand-tight.
Door Panel Removal - see inside back cover:
a. Remove the 2 screws on the bottom of each corner.
b. Find notches in bottom of panel, place fingers on one side
and center notch. Slightly pull on bottom side panel to release 1st
clip. Move over to other side and center notch and pull on bottom
to release 2nd clip, then lower and remove panel.
1. CLOSE DRAIN, remove the filter compartment cover, skimmer
basket, weir, and filter. Fill your spa through the filter compartment
using the CLEANSCREEN pre-filter that attaches to your garden
hose. The water level of your spa should be maintained at a level
2.5 cm above the highest jet in the spa. Reinstall the filter and then
the skimmer basket, and weir once the spa is filled.
2. AFTER THE SPA HAS BEEN FILLED with water and the
equipment compartment door is secured, power must be applied
to the spa.
FIRST activate power to the subpanel from the main house
panel.
NEXT open the door of the electrical subpanel and reset the RCD
breaker.
FINALLY, close and secure the subpanel door.
3. TO CHECK THE OPERATION OF THE JET SYSTEM and to
purge any remaining air from the heating system complete the
following steps:
Press the soft button next to Jet Max to place both jet pumps on
High.
Once the jet system is fully operational (as indicated by strong,
non-surging jets), priming of the spa is complete
To turn off the jets, press
the soft button next to All Off on the
home screen
to turn all functions off simultaneously
If you do not feel a steady stream of water from your jets,
refer to the instructions for priming the pump in the SPA
TROUBLESHOOTING section.
IMPORTANT: Be sure that the diverter is in the middle position.
Page 7
Getting Started
4. SET THE TEMPERATURE CONTROL to the desired temperature
between 38°C (100°F) and 40°C (104°F), then place the spa
cover on the spa and allow the water temperature to stabilize
(approximately 24 hours). Make sure you secure the cover in place
using the cover locks. Periodically check the spa water temperature.
When the water temperature climbs above 32°C (90°F), proceed
to the next step. The spa temperature is pre-programmed to reach
38°C (100°F), and will normally do so within 18 to 24 hours. You may
change the water temperature by pressing the OPTION hard button
then press the soft button next to Temperature, (press soft button
next to
on the control panel to raise the temperature, or lower
temperature by pressing soft button next to ▼). After a few hours,
the water temperature will remain within 1.5°C (3°F ) of your selected
temperature.
5. USING A TEST STRIP AND APPLICABLE CHEMICALS adjust
Total Alkalinity (TA) to 80 ppm, Calcium Hardness (CH) between
75 - 150 ppm (if using Salt System between 25 - 75 ppm), then
spa water pH to between 7.4 and 7.8. These procedures are listed in
the “Water Quality and Maintenance” section.
OPERATION NOTE: Adjusting the Total Alkalinity as the first step is
important, as out-of balance TA will affect your ability to adjust the pH
correctly and will prevent the sanitizer from operating effectively.
When using the FRESHWATER Salt system the Calcium Hardness
must be between 25 - 75 ppm, if hardness is above 75 ppm use
VANISHING ACT (see pg. 11).
IMPORTANT: Activate the Clean cycle (Press the soft button next
to CLEAN on the home screen) before adding spa water chemicals
directly into the filter compartment. Make sure all diverter valves are
set to the middle position.
6. SUPERCHLORINATE THE SPA WATER by adding 1½ teaspoons
of FRESHWATER chlorine (sodium dichlor) per 950 liters (250
gallons) of spa water, then activate the Clean cycle.
7. TEST THE SPA WATER FOR CHLORINE RESIDUAL. If the
residual is between 1 and 5 ppm on the test strips, go on to the next
step. If the residual is less than 1 ppm, activate the Clean cycle, and
then retest, add more chlorine as necessary.
WARNING: High sanitizer levels can cause discomfort to the user’s
eyes, lungs and skin. Always allow the sanitizer level to fall to the
recommended range before using the spa.
8. RECHECK the Total Alkalinity (TA) 40 - 120 ppm, Calcium
Hardness (CH) 75 - 150 ppm (25 - 75 ppm with salt), then spa water
pH between 7.2 and 7.8.
OPERATION NOTE: Make sure you adjust your Total Alkalinity and
pH correctly, this will affect
the sanitizers effectiveness.
The spa is ready for use when the spa water has circulated and
the chlorine level remains between 1 and 5 ppm.
OPERATION NOTE: For proper water circulation during the ten-minute
Clean cycle the following steps should be performed.
Place the diverter valve in the middle (split flow) position
Place air control levers in OFF position by rotating clockwise
Page 8
Water QualIty and
maIntenance
BASIC INFORMATION
It’s important to have clean water. Water maintenance is one of the
least understood, yet most important, areas of spa ownership. Your
dealer can guide you through the process of achieving and maintaining
balanced water in your spa, given your local conditions.
IMPORTANT: Water Terminology can be found at the end of this
section.
Always read & refer to the owner's manual for complete information.
Test your water with a test strip once a week, or each time the spa is
used.
Add chemicals in frequent small amounts to prevent overdosing the
spa.
When using a Salt System, read & refer to seperate owner's manual.
Use the spa only when the chlorine level is between 1-5 ppm or
manually add chlorine as needed.
It is the spa owner's responsibility to prevent over or under
chlorination.
IMPORTANT: Remember to change your water every three to four
months. Check with your CALDERA dealer to determine if water in your
region has unique qualities - such as high metal or mineral content - that
should be addressed.

Maintaining the water quality and the cleanliness of the filters in your spa
is your responsibility. Keeping the spa water balanced prolongs the life
of the spa components and will make the water more comfortable. Your
dealer can guide you through the process of achieving and maintaining
perfect water in your spa, given your local conditions. Your program will
depend on your water’s mineral content, how often you use your spa,
and how many people use it. Watkins Wellness has developed several
water care systems and products to simplify water care which are
available from authorized CALDERA dealers.

CHEMICAL SAFETY
When using chemicals, read the labels carefully and follow directions
precisely. Though chemicals protect you and your spa when used
correctly, they can be hazardous in concentrated form. Always observe
the following guidelines:
Allow only a responsible person to handle spa chemicals. Keep them
out of the reach of children.
Accurately measure the exact quantities specified, never more. Do not
overdose your spa.
Handle all containers with care. Store in a cool, dry, well ventilated
place.
Always keep chemical containers closed when not in use. Replace
caps on their proper containers.
Don't inhale fumes, or allow chemicals to come in contact with your
eyes, nose, or mouth. Wash your hands immediately after use.
Follow the emergency advice on the product label in case of accidental
contact, or if the chemical is swallowed. Call a doctor or the local
Poison Control Center. If a doctor is needed, take the product container
along with you so that the substance can be identified.
Don't let chemicals get on surrounding surfaces or landscaping. Don't
use a vacuum cleaner to clean up chemical spills.
Never smoke around chemicals. Some fumes can be highly flammable.
Don't store any chemicals in the spa equipment compartment.
HOW TO ADD CHEMICALS
TO THE WATER
IMPORTANT: All spa water chemicals must always be added directly
into or in front of the filter compartment while a jet pump is running, and
it must run for a minimum of ten minutes.
TO ADMINISTER SPA WATER CHEMICALS:
1. Fold back the cover and remove the filter compartment cover.
2. To activate the Clean Cycle, press the soft button next to Clean on
the Home Screen.
3. Carefully measure the recommended amount of chemical and
slowly pour it over the filter basket area. Use care not to splash
chemicals on your hands, in your eyes, on the spa sheet surface, or
on the siding.
4. Replace the filter compartment cover and close the spa cover.
Risk of Drowning: Never leave an open spa unattended!
WARNING: High sanitizer levels can cause discomfort to the user’s
eyes, lungs and skin. Always allow the sanitizer level to fall to the
recommended range before using the spa.
IMPORTANT “SUPER CHLORINATION/NON-CHLORINE SHOCK
TREATMENT” NOTE: After administering a super chlorination treatment
or non-chlorine shock to your spa, leave the cover open for a minimum
of 20 minutes to allow the oxidizer gas to vent. A high concentration
of trapped oxidizer gas which may exist as a result of the shock
treatment (not daily sanitation) may eventually cause discoloration or
vinyl degradation to the bottom of the cover. This type of damage is
considered chemical abuse and is not covered under the terms of the
limited warranty.

Water Quality and Maintenance
FUNDAMENTALS OF
WATER MAINTENANCE
Testing: Test the water weekly or each time the spa is used with
convenient 5-way test strips or more accurate liquid/tablet reagent test
kit per instructions. Critical parameters: sanitizer level, pH, Calcium
Hardness (CH), and Total Alkalinity (TA). Store test equipment in a
dark, cool, dry place to maintain potency.
Water Filtration: The filtration used in CALDERA spas helps keep
water clean by circulating sanitizer and removing waste from the spa.
Regularly inspect and clean filters for peak performance.
Chemical Balance/pH Control: It is important to adjust the primary
water parameters (Total Alkalinity, Calcium Hardness, pH) into the
recommended ranges so that they are stabilized or balanced. Balance
the water chemistry every
time you fill the spa with
new water and then during
the life of that body of
water. Keeping the water in
balance prevents damage
by holding the pH in a
safe range and preventing
calcium scale formation
on spa equipment. A low
pH can damage metal
components whereas a
high pH can cause high
levels of calcium to form
scale. Your dealer should
provide a detailed water chemistry orientation soon after your new spa
is filled for the very first time.
The following three water components must be kept in balance to avoid
damage to the spa. Do balance these components in the order they
are listed here as each will help you balance the next using a minimum
amount of chemicals.
1. Calcium Hardness (CH) – CH is the measure of the amount
of dissolved calcium in the water. Low levels can make the
water corrosive and high levels cause scale formation of spa
components. The recommended CH reading is between
75 - 150 ppm. A hardness between 25 - 75 ppm is recommended
with a Salt System. If the CH level is too high, lower it with the
VANISHING ACT calcium remover (pg. 11) per instructions. Once
in balance, the CH reading normally remains stable until new water
is added. Great care must be taken when filling the spa from a
water softener to ensure that the calcium remains in balance and
avoid damage to the spa.
2. Total Alkalinity (TA) - TA is a measure of the waters ability to
resist changes of pH or buffer capacity. A low TA allows the pH to
fluctuate easily. The recommended TA reading is between
40 - 120 ppm. To raise the TA, use pH/Alkalinity Up (sodium
hydrogen carbonate). To lower the TA, use pH/Alkalinity Down
(sodium bisulfate). Once the TA is balanced, it normally remains
stable until the next drain/refill. We recommend you check the TA
reading once per month. Raising/lowering the TA may cause the
pH readings to fluctuate widely. Ignore the pH readings on the test
strip while you are balancing the TA.
3. pH - The pH is the measure of the acidity and alkalinity.
Maintaining the proper pH level will optimize the effectiveness of
the sanitizer, preventing damage to the spa and physical discomfort
for spa users. A low pH dissipates sanitizer, causes corrosion, and
irritates spa users. A high pH level will neutralize sanitizer, promote
scaling and cloud water. The recommended pH reading is between
7.2 - 7.8. To lower the pH level, use FRESHWATER pH/Alkalinity
Down (sodium bisulfate). To raise the pH level, use pH/Alkalinity
Up (sodium carbonate).
Water Conditioners: Spa fill water varies from location to location and
user to user, therefore it is important to consult with your dealer for an
appropriate program.
a. VANISHING ACT – High levels of calcium and some minerals
can be removed from the water with the single use VANISHING
ACT. High calcium levels can cause scale formation on the spa
equipment and shell.
b. CLEAN SCREEN pre-filter –The CLEAN SCREEN pre-flter
should be used at every fill and top-off to remove contaminants
from the fill water, especially iron, copper, and manganese. Many
water sources including well water contain high concentrations of
minerals that can cause staining of the shell and plastics.
c. Stain and Scale control – For water high in calcium and minerals,
it may be necessary to use an anti-scalant like Stain and Scale
control. As water evaporates from your spa and new water is
added, the amount of dissolved minerals like calcium, copper, iron,
and manganese will increase. (Minimize evaporation by keeping
the cover on the spa whenever possible.) High iron or copper
content in the water may produce green or brown stains on the spa.
d. Foam Inhibitors - Soap is introduced into the spa water from users’
bodies and swimming apparel and can cause the spa water to
foam when the jets are used. Low levels of calcium hardness
(soft water) can increase foaming. Although ozone can oxidize
soap residual, it may become necessary to add Foam Inhibitors
to suppress the foam. Excessive soap in the water may require a
water change to resolve.
Oxidizers: Ozone and Monopersulfate (MPS) are oxidizers used to
prevent the buildup of contaminants, maximize sanitizer efficiency,
minimize combined chlorine, and improve water clarity. They are to be
used in conjunction with EPA registered sanitizers. The FRESHWATER
III high output ozone system uses Corona Discharge technology to
produce a high concentration of ozone which is injected into the spa
water 24 hours per day. Chlorine-Free Oxidizer, Monopersulfate (MPS)
is a granular oxidizing chemical.
Sanitizers: Maintaining the recommended residual level of an EPA
registered sanitizer at all times will decrease the occurrence of unsafe
bacteria and viruses in your spa water. The recommended Free
Available Chlorine (FAC), the amount of available chlorine sanitizer, is
3 - 5 ppm. A low FAC can allow bacteria and viruses to grow rapidly
in the warm water, and a high FAC can cause discomfort to the user’s
eyes, lungs, and skin. Each sanitizer carries its own instructions
regarding how much to use and when to add it to the spa water.
Consult your dealer for their recommendations and instructions on
proper sanitizing of the spa.
WATKINS WELLNESS recommends the following sanitizers:
FRESHWATER SALT SYSTEM
Concentrated Chlorinating Granules
Liquid sodium hypochlorite (do not use splashless)
WATKINS WELLNESS also approves the following sanitizers:
Biguanide
WARNING: DO NOT use tri-chlor chlorine, bromo-chloro-dimethyl-
hydantoin (BCDMH), or any type of compressed bromine or chlorine,
acid or any type of sanitizer which is not recommended by WATKINS
WELLNESS.

THE CALDERA SPA WATER
MAINTENANCE PROGRAM
FILLING THE SPA WITH WATER
Use the CLEAN SCREEN pre-filter to remove unwanted contaminants
such as rust, dirt, detergents, and algae from the fill water. Dissolved
metals, copper, iron, and manganese are also removed. Instructions are
included with the CLEAN SCREEN pre-filter. Always fill the spa through
the filter compartment. Do not fill your spa using water from a swimming
pool as pool
chemicals are very different from those used in a spa and
can damage your spa.
ADDING CHEMICALS TO THE WATER
All spa water chemicals, including granulated dichlor, MPS, granulated
pH increaser or decreaser, granulated total alkalinity increaser, liquid
stain and scale inhibitor, and liquid defoamer must always be added
directly into the filter compartment while the jet pump is running in its
high speed mode, and it must run for a minimum of ten minutes with the
cover off. Use the Clean button/feature to ensure that the chemicals are
properly mixed when adding.
BUILDING A SANITIZER ROUTINE
During the first month of ownership, measure the sanitizer residual
daily in order to establish a baseline of sanitizer needed vs. spa usage.
Sanitizer needed is the amount of Free Available Chlorine needed to
accommodate the number of users and their combined usage time. For
example, two spa users for twenty minutes every day creates regular
demand on the sanitizer that is used to determine how much sanitizer
to add in order to maintain the proper residual. If the usage pattern
increases dramatically with invited guests, the amount and frequency of
sanitizer required increases dramatically.
PERFORMING SUPER CHLORINATION/
NON-CHLORINE SHOCK TREATMENT
A weekly or monthly super chlorination (1.5 tsp dichlor/950 liters (250
gallons)) or shock (4tbs mps/950 liters (250 gallons)) may be required
of your chosen sanitation program. Increasing chlorine to 5 ppm for
24 - 48 hours removes excess waste and chloramines from the water.
Sodium dichlor is 6x stronger than MPS and may be a more appropriate
for those users that experience heavy bather load conditions. Operate all
jets and leave the cover open for a minimum of 20 minutes to allow the
oxidizer gas to vent to prevent damage and discoloration to the cover
and pillows after administering a super chlorination or shock to your spa.
This type of damage is considered chemical abuse and is not covered
under the terms of the limited warranty.
IMPORTANT
: Always allow the Free Available Chlorine to fall below 5
ppm before using your spa.
DANGER: Never leave an open spa unattended, especially if
there are children present!
FRESHWATER WATER CARE SYSTEM
(OPTIONAL)
The FRESHWATER Salt System converts water and sodium chloride
salt into chlorine sanitizer. The FRESHWATER Salt System is
compatible with chlorine based systems and chemicals. Although the
system is reduced maintenance, it is not automatic. It is important that
the user regularly tests and balances the water. A calcium hardness
between 25 - 75 ppm is recommended to extend the life of the
hardware. Consult the FRESHWATER Salt System manual for additional
instructions.
ADDITIONAL WATER CARE PRODUCTS
CLEAN SCREEN Pre-filter
Concentrated Chlorinating Granules, Sodium Dichlor
Chlorine-Free Oxidizer, Monopersulfate (MPS)
High output ozone system
Silver Ion purifier
The Silver Ion purifier introduces silver ions into the spa water via
erosion of silver infused beads which inhibits bacteria growth. When
combined with MPS, or chlorine, waste is oxidized and removed from
the water.
It is important to follow the recommended application and maintenance
programs outlined for each product’s use. If the spa is being used over
an extended period of time, such as a whole afternoon or evening,
additional sanitizer will be needed.
Required: Weekly Super Chlorinate/Shock the spa to reactivate the
silver ion cartridge, allow the release of silver ions, and quickly destroy
any remaining contaminants. Without this weekly shock treatment, the
silver ion cartridge may stop releasing silver ions into the water.
IMPORTANT: Use only granulated sodium dichlor or liquid chlorine
sanitizer. Silver is not compatible with bromine and biguanides. Don't use
a water clarifier. Clarifiers will cause the spa water to become cloudy.
MANUAL CHLORINE (SODIUM DICHLOR)
Watkins Wellness recommends the use of
FRESHWATER
Concentrated
Chlorinating Granules (sodium dichlor) for sanitizing the water. Sodium
dichlor is preferred because it is totally soluble, dissolves quickly, and is
nearly pH neutral. The recommended Free Available Chlorine (FAC), the
amount of available chlorine sanitize the spa, 3 -5 ppm.
If the FAC is too low: Increase the FAC by adding granulated sodium
dichlor.
If the FAC is too high: Allow time to pass and the FAC level will
naturally drop over time.
If the spa smells of chlorine: super chlorinate or shock the spa FAC
chlorine does not have an odor whereas combined spent chlorine
(chloramines) has a strong chlorine odor that can be eliminated by
shocking the water.
IMPORTANT: There are several forms of stabilized chlorine available
for use in spas and swimming pools. It is extremely important to choose
one specifically designed for spas. Use of an incorrect product such
as tri-chlor which has a very low pH (2.6) and dissolves too quickly in
hot water, results in extremely high levels of chlorine that WILL cause
damage to your spa. Use of a liquid or compressed bromine/chlorine
or unapproved sanitizer WILL damage your spa and is specifically not
covered under the terms of the limited warranty.

VANISHING ACT INSTRUCTIONS
MAKENA SALINA MARTINIQUE
SEYCHELLES REUNION KAUAI
Instructions for Use:
1. After filling your hot tub, use a test strip to measure the
hardness level of the water. If hardness is above 100 ppm,
use the VANISHING ACT calcium remover to soften the water.
Suggested Hardness Level: between 75 - 150 ppm, (it must
be between 25 - 75 ppm when using the FRESHWATER Salt
System in order to work).
2. Rinse the VANISHING ACT calcium remover with running water
until water runs clear. When placed in the hot tub, slight color
transfer to the water may occur and can be easily resolved with
chlorine.
3. Locate your spa above to determine which jet suction fitting the
VANISHING ACT calcium remover will be placed up over. Use
the circle to determine location.
a. Press
OPTIONS hard button on the Control panel.
Press the soft button next to Set-Up.
Press the soft button next to More
Press the soft button next to Soft Water to start low speed jet
pump for 6 hours.
Place the VANISHING ACT calcium remover firmly against
the associated jet suction fitting.
b. Test the spa water for hardness after jets shut off, which will take
around 6 hours.
IMPORTANT:
Always make sure water is balanced and properly sanitized,
using the EPA approved sanitizer, before entering your hot
tub.
For maximum effectiveness, ensure that the calcium
remover remains on the suction fitting while the calcium
remover is in use.
Calcium remover may not be necessary if water hardness is
already in or below the suggested range.
Multiple calcium removers may be needed if initial water
hardness is above 200 ppm.
Page 12 Water Quality and Maintenance
OZONE MAINTENANCE (OPTIONAL)
If reduced or no ozone bubbles are coming from the heater return
(clogged ozone injector) or no ozone, clean the injector:
DANGER: Nitric acid accumulates in the air lines of the ozonator
and injector, and will cause severe chemical burns if direct skin contact
is made. Always wear protective gloves, glasses and clothing when
working on the ozonator or injector lines. To prevent inhalation or
ingestion of the nitric acid, DO NOT blow or inhale with your mouth to
any of the adapters, fittings or tubing of the ozonator or injector air lines.
1. Place 0.5 liter of white vinegar into a cup or bucket.
2. Carefully loosen the long tubing attached to the bottom of the
ozonator, located in the equipment compartment.
3. Place the end of the tubing into the vinegar, making certain that the
end of the tubing sits at the bottom of the container.
4. Run the spa until all 0.5 liter of the vinegar are gone. This should allow
an ample flow of vinegar to be run through the injector and clear the
blockage.
5. Reinstall the tubing to the bottom of the ozonator.
Water chemistry damage is not covered by the warranty. The chemical
levels and water quality in the spa are under your direct control.
With proper basic care, the spa will provide many years of hot water
relaxation. If you are unsure about any chemical or its usage in the spa,
contact your Authorized Dealer, or Watkins Wellness.
DO:
Add all chemicals slowly into the filter compartment with the jet pump
operating for ten minutes.
Use special care if using baking soda to clean either the interior or
exterior plastic surfaces.
IMPORTANT: Watkins Wellness DOES NOT recommend the use of any
floating chemical dispenser. Damage to the spa shell or components
caused by a floating chemical dispenser is specifically not covered under
the terms of the limited warranty. Floating dispensers can become
trapped in one area and cause an over-sanitization or release large
chunks of sanitizer that very quickly chemically burn the shell and cover.
DON'T:
Use compressed sanitizers.
Use a floater type sanitization system as a low or no maintenance
solution to your spa maintenance program.
Use a sanitizer which is not designed for spas.
Use swimming pool (muriatic) acid to lower pH.
Broadcast or sprinkle the chemicals onto the water surface. This
method may cause chemically-induced spa surface blistering (chemical
abuse).
VACATION WATER CARE
INSTRUCTIONS
If you plan to be away from home, follow these instructions to ensure
that the water quality of your spa is maintained:
SHORT TIME PERIODS (3-5 DAYS)
1. Adjust the pH by following the instructions outlined in the Water Quality
and Maintenance section.
2. Sanitize the water by following the shock procedures also listed in the
Water Quality and Maintenance section.
3. Lock your cover in place using the coverlocks.
4. Upon your return, sanitize the water by following the shock procedures,
and balance the pH.
LONG TIME PERIODS (5-14 DAYS)
Prior to leaving:
1. At least one day before you leave, set the temperature to its lowest
level. This setting should represent an approximate water temperature
27°C (
80°F
).
IMPORTANT: Spa water oxidizers such as sodium dichlor (chlorine)
maintain their level of effectiveness substantially longer in warm water
27°C (
80°F
)
than in hot water 38°C - 40°C (101°F to 104°F).
2. Adjust the pH as required. Sanitize the water by following the shock
procedures.
Upon your return:
3. Sanitize the water by following the shock procedures. Return the set
temperature to its original setting. The spa water will be safe for you to
use once the Free Available Chlorine residual level has dropped below
5.0 ppm.
IMPORTANT: If you will not be using your spa for an extended period
of time (in excess of 14 days) and an outside maintenance service (or
neighbor) is not available to assist with the water maintenance, draining
or winterizing of the spa is recommended.
Page 13
SUPPLEMENTAL WATER MAINTENANCE
Proper water sanitation and mineral balance (pH control) are absolutely
essential for a complete spa water maintenance program. Here are two
other popular water additives that are optional:
Mineral Deposit Inhibitors
As water evaporates from your spa and new water is added, the amount
of dissolved minerals will increase. (Minimize evaporation by keeping
the cover on the spa whenever possible.) The spa water may eventually
become “hard” (Calcium Hardness too high) enough to damage the
heater by calcifying its surface. Proper pH control can minimize this.
Normal soap build-up will require water replacement regularly enough
that mineral deposits normally are not a problem.
Occasionally, high iron or copper content in the water may produce
green or brown stains on the spa. A stain and scale inhibitor may help to
reduce these metals.
IMPORTANT: Well water may contain high concentrations of minerals.
The use of a low water volume, extra-fine pore water filter (in-line pre-
filter such as the CLEAN SCREEN pre-filter) will help to remove many of
the larger particles during the filling of the spa. In-line pre-filters can be
purchased at your local CALDERA dealer.
Foam Inhibitors
Spa water requires changing due to the buildup of soap in the water.
Typically, soap will cause the spa water to foam when the jets are used.
Soap is introduced into the spa water from two sources: users’ bodies,
which retain a soap residual after showering, and swimming apparel,
which retains soap after washing.
Foam inhibitors can suppress foam, but cannot remove soap from the
water. Soap is very difficult to remove from the water because soap is
not oxidized by any chemical added to the spa. Only ozone can oxidize
soap. Eventually the soap build-up in the water will be concentrated,
resulting in an unclean feeling on the bather’s skin, which is impossible
to remedy. When this occurs, it’s time to drain and refill the spa.
Depending on the soap input, the water should last about four months
before needing to be drained.
GLOSSARY
The following chemical terms are used in this Water Quality and
Maintenance section. Understanding their meaning will help you to
better understand the water maintenance process.
Bromamines: Compounds formed when bromine combines with
nitrogen from body oils, urine, perspiration, etc. Unlike chloramines,
bromamines have no pungent odor, and are effective sanitizers.
Bromine: A halogen sanitizer (in the same chemical family as chlorine).
Bromine is commonly used in stick, tablet, or granular form however,
stick and tablet form should NOT be used.
Calcium Hardness: The amount of dissolved calcium in the spa water.
This should be between 75 - 150 ppm and when using a Salt System
between 25 - 75 ppm. High levels of calcium can cause cloudy water
and scaling. Low levels can cause harm to the spa equipment.
Chloramines: Compounds formed when chlorine combines with
nitrogen from body oils, urine, perspiration, etc. Chloramines can cause
eye irritation as well as having a strong odor. Unlike bromamines,
chloramines are weaker, slower sanitizers.
Chlorine: An efficient sanitizing chemical for spas. Watkins Wellness
recommends the use of sodium dichlor-type granulated chlorine. This
type is preferred because it is totally soluble and nearly pH neutral.
Chlorine (or Bromine) Residual: The amount of chlorine or bromine
remaining after chlorine or bromine demand has been satisfied. The
residual is, therefore,
the amount of sanitizer which is chemically available to
kill bacteria, viruses and algae.
Corrosion: The gradual wearing away of metal and plastic spa parts,
usually caused by chemical action. Generally, corrosion is caused by low
pH or by
water with levels of TA, CH, pH or sanitizer which are outside the
recommended ranges.
Halogen: Any one of these five elements: fluorine, chlorine, bromine,
iodine, and astatine.
MPS: Monopersulfate is a non-chlorine oxidizer.
Nitric Acid: The formulation of nitric acid, a highly corrosive chemical,
is a byproduct of the ozone generating process. Nitric acid is produced
in very small quantities and is readily dissolved in the water stream with
ozone.
Oxidizer: The use of an oxidizing chemical is to prevent the buildup of
contaminants, maximize sanitizer efficiency, minimize combined chlorine
and improve water clarity. See MPS and Ozone.
Ozone: Ozone is a powerful oxidizing agent which is produced in
nature and artificially by man. Ozone forms no byproducts, oxidizes
chloramines, and will not alter the water’s pH.
pH: The measure of the spa water’s acidity and alkalinity. The
recommended pH for the spa water is 7.2 to 7.8. Below 7.0 (considered
neutral), the spa water is too acidic and can damage the heating system.
Above 7.8, the water is too
alkaline and can result in cloudy water, and
scale formation on the shell and heater.
ppm: The abbreviation of “parts per million”, the standard measurement
of chemical concentration in water. Identical to mg/l (milligrams per liter).
Reagent: A chemical material in liquid, powder, or tablet form for use in
chemical testing.
Sanitizer: Sanitizers are added and maintained at recommended
residuals to protect bathers against pathogenic organisms which can
cause disease and infection in spa water.
Scale: Rough calcium-bearing deposits that can coat spa surfaces,
heaters, plumbing lines, and clog filters. Generally, scaling is caused by
mineral content combined with high pH. Additionally, scale forms more
readily at higher water temperatures.
Super-Chlorination: Also known as “shock treatment.” Super-
Chlorination is a process of adding significant doses of a quick dissolving
sanitizer (“dichlor” is recommended) to oxidize non-filterable organic
waste and to remove chloramines and bromamines.
Total Alkalinity (TA): The amount of bicarbonates, carbonates, and
hydroxides present in spa water. Proper total alkalinity is important for
pH control. If the TA is too high, the pH is difficult to adjust. If the TA is
too low, the pH will be difficult
to hold at the proper level. The desired
range of TA in spa water is 40 to 120 ppm.

button. After a period of non-use (45 seconds) the display will go back to
the Home screen and will remain on for several minutes before going to
sleep mode. Pressing any button will wake up a sleeping display.
INDICATOR ICONS
At a glance, the indicator icons are visible on the main control panel.
The indicator icons work independently from the rest of the control panel
display. They are displayed so that you may know the status of your spa
at a glance. NOTE: Indicators will not be visible when Main Control Panel
goes into sleep mode.
READY Indicator: The READY indicator will display when the
spa water temperature is within 1°C (2°F) of the set
temperature, and will turn off when the temperature is outside of
that range. If you increase or decrease the temperature setting
of the spa, the ready indicator will turn off until the water
temperature reaches the acceptable range for the new
temperature setting. A flashing READY indicator means a
problem may exists with the temperature sensor (see
Troubleshooting section for more information)
Spa Light Indicator: The Spa Light indicator is displayed when
any light inside the spa is on. The indicator icon will remain solid
as long as any manual light is activated.
Spa or Temperature Lock Indicator: The Spa or Temperature
Lock indicator is displayed when either the Spa Lock,
Temperature Lock or both are activated. Lock indicator does not
flash.
Jet Pump Indicator: The Jet Pump indicator is displayed
whenever a jet pump is on. The Jet Pump indicator will flash
whenever the spa is in the ten-minute Clean Cycle or Auto
Clean Cycle.
Summer Timer Indicator: The Summer Timer indicator is
displayed when the summer timer is set to ON. In summer timer
mode, the heater and circulation pump cycle are off for eight
hours. The Summer Timer indicator will not flash.
POWER Indicator: The POWER indicator is ‘on’ when the spa
is properly supplied with power. It also provides a diagnostic
function–a flashing power indicator indicates that the heater high
limit has tripped, meaning that either the spa water is above its
acceptable temperature range, or a malfunction has occurred
within the spa (such as low circulation due to clogged filters).
When the power indicator is not displayed it means that there is
a problem with the spa control box or the power supplied to the
spa (see Troubleshooting section for more information).
HOME SCREEN
The temperature displayed in the center of the Home screen is the actual
temperature of the spa water. If the READY icon is displayed and solid on
the control panel, then the actual spa temperature is within 1°C (2°F) of
the set temperature. The corner soft button functions are as follows:
MEMORY
This feature will recall the last active
setting for jets and lights prior to
pressing the All Off button.

Spa care and maIntenance
Your CALDERA spa is manufactured from the highest quality, most
durable materials available. Even so, the spa care and maintenance
program you develop will ultimately determine how long your spa, and its
individual components, will last. Regular maintenance and following the
advice in this section will help you to protect your investment.
FILTER MAINTENANCE
At least once a week, check and clean the skimmer basket and weir to
ensure proper filter flow. Remove leaves, foreign matter, and debris. It is
very important to keep your spa filter cartridge clean and free of particles
to ensure proper water flow. A clean filter enables the hydrotherapy
system to function properly and allows for more efficient filter cycles.
Depending on how frequently your spa is used, we recommend cleaning
the spa filter cartridge every four weeks. If this is not done, the filter may
clog and restrict water flow, which causes improper filtration, poor jet
performance and may possibly freeze.
IMPORTANT: The frequency and duration of use, and the number of
occupants all contribute to determining the appropriate time between
filter cleanings. More use means that more frequent filter cleanings will
be required.
FILTER CARTRIDGE REMOVAL AND
CLEANING INSTRUCTIONS
Turn the power to the spa off, then proceed as follows:
Push down slightly and turn filter basket counter-clockwise to unlock, then
pull out the basket and floating weir.
Carefully pull up the filter cartridge and bring it out of the spa.
Always clean the filter using a filter degreaser to remove mineral and oil
build-up. Simply soak the filter in the degreaser (according to the package
directions), then place the filter on a clean surface and spray until clean
using a garden hose. It may be necessary to rotate the filter while spraying
to remove any debris lodged between the filter pleats. Re-insert filter
cartridge.
To return basket and floating weir, insert and rotate clockwise to lock into
position. Then turn spa’s power back on.
NOTE: Replacement filter cartridges are available from your CALDERA
dealer. Refer to the back of this manual to determine the appropriate
size for your spa.
DIVERTER VALVE MAINTENANCE
If your spa’s diverter valves become difficult to turn, it is likely that sand
or grit is lodged inside the valve body. It is very important that this debris
is removed as soon as possible to avoid damage to the valve. To clean
the valves, follow these steps:
1. Turn off power to the spa.
2. Remove the diverter valve’s handle by pulling upward while rocking it
back and forth.
3. Unscrew the cap ring.
4. Remove the valve body by pulling it upward.
5. Wipe the valve body and the interior walls of the valve clean.
6. Lubricate the o-rings with a waterproof lubricant available from your
CALDERA dealer.
7. Reassemble the valve and turn on power to the spa.
VERSASSAGE JET MAINTENANCE
If you notice that the VERSASSAGE jet spins slower than when the
spa was new, or the jets are sticking, the cause may be built-up deposits
inside the jet bearings. To remove the deposits, use the following
instructions:
1. With the spa off, rotate the VERSASSAGE jet face counter-
clockwise until it stops.
2. Once the face stops rotating, use a little extra force to rotate the
face even more counter-clockwise past the locking position until it
stops. Pull face with the body away from the spa.
3. After flushing the bearing inside the body with water, spin the
rotating eye. It should spin very freely. If it does not, place the
bearing end in a cup of vinegar (the vinegar will soften any
deposits). Allow it to soak overnight. The next day, flush with
water and repeat the spin test.
NOTE: If the jets still don't spin freely, a second night of soaking
maybe required. If the bearing still does not spin, you will need to
purchase a replacement assembly from your CALDERA dealer.
COLD WATER REFILL
When refilling your spa if the tap water is below 10° C (50° F) the
spa may go into a High Limit Protection mode (causing your spa to
stop functioning). If high limit tripping does occur, the fastest way to
reactivate the spa control system is to first disconnect power to the
spa completely, then warm the two sensors on top of the heater and
the vinyl tubing (located in the
equipment compartment) with a
hair dryer for approximately 10
minutes. Once you believe the
sensors and heater tubing
have been warmed sufficiently,
reconnect power to the spa.
Blending warm water with the cold
tap water so it exceeds 10° C
(50° F) during the refilling process will also achieve the same results if
that is an option for you.

DRAINING YOUR SPA
1. Turn off all GFCI breakers in sub-panel, or main electrical panel.
2. Locate the drain valve for the spa (lower front of the spa) and
remove the drain cap. Attach the inlet of a garden hose to the drain
valve and route the outlet of the hose to an appropriate draining
area.
NOTE: Spa water with a high sanitizer level may harm plants and
grass.
3. Open the drain valve by turning the knob. The spa will drain by
gravitational flow.
IMPORTANT: All models will drain almost completely through the
drain valve. Equipment such as the jet pump and heating system
may not completely drain. Any water remaining within the plumbing
or equipment after draining will only need to be removed if the spa
is being winterized.
4. After your spa is empty, clean the shell and filter cartridge.
5. Close the drain valve and reinstall the drain cap.
6. Install new filter or clean existing with filter cleaner.
7. Follow the “START-UP PROCEDURES” to refill your spa.
PREVENTION OF FREEZING
Your spa has been designed and engineered for year-round use in
any climate. In some areas, extremely cold temperatures below -12°C
(10°F) combined with strong wind, may cause partial freezing of the jet
pump, even though the water inside the spa remains at the selected
temperature. The energy efficiency of the spa may also decrease during
these cold periods, as the heater will cycle more frequently. As an
additional precaution against partial freezing of some of the components,
the equipment compartment can be insulated with an insulating kit
(available from your local dealer). This insulating kit will also help to
maximize the spa’s energy efficiency.
NOTE: When warmer weather returns approx. 16° - 21°C (60 - 70°F),
the insulating kit must be removed to prevent overheating of the jet
pump.
WINTERIZING YOUR SPA
If you leave the spa unused for a long period of time in severely cold
weather, you should drain the spa and winterize it to avoid accidental
freezing due to a power or equipment failure.
DANGER: Use only Propylene Glycol as your anti-freeze (available
at most RV or marine supply stores). This is non-toxic. Never use an
automobile anti-freeze (Ethylene Glycol) since it is toxic!
WARNING: Failure to follow these instructions correctly can lead to
freeze damage not covered by warranty. It is strongly recommended
that you contact your local dealer to perform this service.
1. Drain your spa following the Draining Your Spa section in the
owner’s manual.
2. Remove the filter cartridge, clean and store in a dry place.
IMPORTANT: These additional instructions must be utilized when
draining and winterizing your spa in climates where the temperature
falls below 0°C (32°F). A 19 liter (5 gallon) combination (vacuum/
blower) wet/dry shop vac must be used to effectively remove water
that is trapped inside the plumbing lines.
3. Attach the vacuum hose to the vacuum side of the shop vac.
Vacuum all openings and orifices as follows:
a. Jet openings: start with the jets at the top and move
downward (if suction is coming from another jet, block off the
other jet using a large rag – this will help pull out the water that
is trapped deeper inside the main line).
b. Filter suction fittings and filter compartment.
c. Main drain outlet (it may be necessary to cover the drain grate
tightly with a rag when vacuuming the main drain to ensure
water is drawn completely from the internal plumbing system).
4. Thoroughly dry the spa shell with a clean towel.
5. Remove pump door first. Once door is removed unscrew the pump
drain plugs located on the front of the pump housing. Allow all
water to drain out. Place the drain plugs in a ziplock bag and store
near the pumps. Replace the drain plugs on Start-up.
6. Unscrew the pump unions and allow the water to drain. Loosen
and remove hose attached to circulation pump to allow any
remaining water from heater and spa to drain out. Replace
circulation pump hose once water is drained. NOTE: Tighten the
pump unions prior to filling the spa.
7. Replace the main drain cap.
8. Using a long-extension funnel, pour anti-freeze into all standpipes,
filter suction fittings, jet orifices and water feature orifices. Add
enough anti-freeze to ensure adequate protection – in many
cases, you will see the liquid in the orifice, or coming out of another
location.
CAUTION: Use only Propylene Glycol as your anti-freeze. This is
non-toxic. Never use an automobile anti-freeze (Ethylene Glycol)
since it is toxic!
9. Close the spa cover and fasten the cover tie downs. Cover the spa
cover with two pieces of plywood to evenly distribute the weight of
snow and ice. Secure a plastic sheet, or tarp, over the spa cover
and plywood.
10. Replace the equipment access door, if removed.
OPENING INSTRUCTIONS:
1. Remove plywood and plastic sheet. Open the spa cover by
unfastening the cover tie downs.
2. Follow the Start-up Procedures in the Getting Started section of
the Owner’s Manual. Do not install filters to prevent them from
exposure to the anti-freeze.
3. As part of this process, superchlorinate the spa water by adding
three teaspoons of chlorine (sodium dichlor) per 950 liters (250
gallons) of spa water into the filter compartment. This is twice the
normal amount of chlorine needed for superclorination. This extra
amount of chlorine is needed to destroy the anti-freeze.
NOTE: A defoamer may be needed to decrease the amount of
foam caused by the anti-freeze.
4. Drain your spa to ensure removal of anti-freeze. Do not drain water
on grass or plants due to excessive chlorine level.
5. After the spa has completely drained, re-install your filter and
follow the Start-up Procedures in the Getting Started section of the
Owner’s Manual.
IMPORTANT: Always keep spa covered when not in use, whether
it is empty or full.

CARE OF THE SPA PILLOWS
The spa pillows will provide years of comfort if treated with care. They
have been positioned above the water level to minimize the bleaching
effects of chlorinated water and other spa water chemicals. To extend
their life, whenever the spa shell is being cleaned, the spa pillows should
be removed and cleaned. Body oils can be removed with a mild soap
and water solution. ALWAYS rinse off the spa pillows thoroughly to
remove any soap residue. If the spa is not going to be used for a long
period of time (that is during a vacation or if the spa is winterized), or
when the spa water is being super-chlorinated, the spa pillows should be
removed until the next use of the spa.
TO REMOVE AND REPLACE THE SPA
PILLOWS:
1. Carefully lift one end of the pillow away from the spa shell.
2. Continue lifting one end until all pillow retainers are released from the
pillow.
IMPORTANT: Just pulling the pillow straight up and out of the shell
recess will eventually damage the pillow. This abuse is not covered
under warranty.
3. To reinstall the spa pillow, carefully bend the pillow slightly to allow
one of the pillow retainers to slip into the recess in the back of the
pillow.
4. Keeping the pillow slightly bent, slide the other pillow retainer into the
recess in the back of the pillow.
5. After all the pillow retainers are in place, press the pillow down into
the recess in the spa shell.
CARE OF THE EXTERIOR
SPA SHELL
Your CALDERA
spa has an acrylic shell. Stains and dirt generally will
not adhere to your spa’s surface. A soft rag or a nylon scrubber should
easily remove most dirt. Most household chemicals are harmful to your
spa’s shell. Always rinse off any spa shell cleaning agent with fresh
water.
SPA SKIRT
When cleaning the skirt of your spa, use only a soft cloth or sponge with
a mild soap and water solution. The use of an abrasive type cleaner or
applicator will be harmful to the exterior finish. Always thoroughly rinse
off the spa skirt with fresh water.
CARE OF THE SPA COVER
WARNING: The cover is a manual safety cover that meets or
exceeds all prevailing requirements of ASTM Standards for spa safety
covers when installed and used correctly as of the date of manufacture.
Non-secured or improperly secured covers are a hazard. Open the cover
to its fully open position before use.
VINYL COVER
The vinyl spa cover is an attractive, durable foam insulation product.
Monthly cleaning and conditioning are recommended to maintain its
beauty.
TO CLEAN AND CONDITION THE VINYL
COVER:
1. Remove cover from the spa and gently lean it against a wall or fence.
2. With a garden hose, spray cover to loosen and rinse away dirt or debris.
3. Using a large sponge and/or a soft bristle brush and a very mild soap
solution (1 teaspoon dishwashing liquid with 7.5 liters [2 gallons] of
water) or baking soda (sodium bicarbonate), scrub the vinyl top in a
circular motion. Do not let the vinyl dry with a soap film on it before it
can be rinsed clean.
4. Scrub the cover’s perimeter and side flaps. Rinse clean with water.
5. Rinse off the underside of the cover with water only (don't use soap),
and wipe it clean with a dry rag.
6. Use FRESHWATER Cover Shield to protect the cover.
SERVICE NOTE: To remove tree sap, use cigarette lighter fluid (not
charcoal lighter fluid). Use sparingly, and rinse with a saddle soap solution
immediately afterwards, then wipe dry.
IMPORTANT REMINDERS:
DO remove snow buildup to avoid breakage of the foam core from
the additional weight of the snow.
DO lock cover lock straps to secure the cover when the spa is not
in use.
DO NOT drag or lift the spa cover using either the flaps or the cover
lock straps.
DO NOT walk, stand, or sit on the cover.
DO NOT place any metal or heat transferring object on the cover
or place any type of plastic tarp or drop cloth over the cover as
this may result in a melted foam core, which would not be covered
under the warranty.
DO NOT use any lifting mechanisms, chemicals or cleaners except
those recommended by Watkins Wellness or its Authorized Sales
and Service Dealer.

ELECTRICAL REQUIREMENTS AND
PRECAUTIONS
Your CALDERA spa has been carefully designed to give you maximum
safety against electrical shock. Connecting the spa to an improperly
wired circuit will negate many of the spa’s safety features. Improper
wiring may also cause electrocution, risk of fire, and other risks of
injuries. Please read and follow the electrical installation requirements
and instructions for your spa completely! Unless otherwise stipulated by
your dealer, THIS IS YOUR RESPONSIBILITY.
SERVICE NOTE: All CALDERA spas have diagnostic functions that
are displayed on the control panel. Four flashing lines are visible on the
control panel if the heater high limit thermostat has tripped. If the four
flashing lines are visible, follow the instructions in the troubleshooting
section to identify and correct the cause. The four flashing lines will
stop flashing once the problem has been corrected.
CALDERA SPAS MUST BE WIRED IN ACCORDANCE WITH ALL
APPLICABLE NATIONAL AND LOCAL ELECTRICAL CODES. ALL
ELECTRICAL WORK SHOULD BE DONE BY AN EXPERIENCED,
LICENSED ELECTRICIAN. WE RECOMMEND THE USE OF
APPROPRIATE ELECTRICAL CONDUIT, FITTINGS, AND WIRE FOR
ALL CIRCUITS.
The KAUAI spa requires a 16 amp, single phase, 220-240 volt, three
wire service (one line, one neutral, one ground). By using a 16 amp
service, the heater will not operate whenever the jet pump is running
in the high speed mode. Upgrading to a 32 amp service will allow the
heater and the high speed mode of the jet pump to run simultaneously.
When upgrading the KAUAI spa to a 32 amp service, jumper
JP3 must be removed from the control box prior to powering up
the spa. The MAKENA, SALINA, MARTINIQUE, SEYCHELLES
and REUNION spas require a dual electrical service using a 16 & 25
amp breaker and wired per the illustration found on the next page.
Additionally, one main disconnect switch with at least 3mm separation
between contacts must be used for all electrical circuits to the spa.
Mount the subpanel according to local codes, but not closer than 1.5
meters (5') away. Your spa must be supplied by a residual current
device (RCD) - with a tripping rating not exceeding 30 mA in an
electrical subpanel.
CONDUIT INSTALLATION
INSTRUCTIONS
1. To connect the electrical service, first remove the 2 screws from
the equipment compartment door. Slightly pull the door panel out
from the bottom using the notches in the door panel on one side
then the other, then lower and remove door panel from the spa.
2. Locate the control box. Loosen the screws on the front of the
control box. Remove the screws and the control box cover.
3. Insert power wires into access opening from either side below the
front corner, you will find a plastic cap attached to spa.
4. Connect the supply conduit to the control box and connect the
wiring as detailed below and on the wiring diagram label on the
inside of the control box cover.
WARNING: Removing or bypassing any RCD breaker will result in
an unsafe spa and will void the spa’s warranty.
IMPORTANT: Should you ever find the need to move or relocate your
CALDERA spa, it is essential that you understand and apply these
installation requirements. Your CALDERA spa has been carefully
engineered to provide maximum safety against electric shock.
Remember, connecting the spa to an improperly wired circuit will
negate many of its safety features.
NOTE: Long wiring runs may require larger-gauge wire than stated.

SITE PREPARATION
You probably have a spot picked out for your new spa, whether it’s
indoors or outdoors, on a patio or on a deck. Please make sure you
check the following:
Always put your spa on a structurally sound, level surface. A
filled spa can weigh a great deal. Make certain that the location
you choose can support the weight of your filled spa.
Don’t forget to level your spa before filling it. (See the Spa
Leveling Preparation.)
Locate your equipment compartment, which houses all of the
electrical components, in a place where water will drain away
from it. Allowing water into the equipment compartment can
damage the electronics, or may result in tripping your house’s
circuit breaker.
Leave yourself easy access to the circuit breakers in the
subpanel.
Leave access to the equipment compartment for periodic spa
care and maintenance.
WARNING: Damage to the spa’s equipment compartment
components or internal plumbing as a result of rodent
infestation is NOT covered under your warranty!
OUTDOOR AND PATIO INSTALLATION
No matter where you install your new spa, it’s important that you have
a solid foundation to support it. Structural damage to the spa, resulting
from incorrect installation, or placement on an inadequate foundation, is
not covered under the spa’s limited warranty.
If you install the spa outdoors, we recommend a reinforced concrete pad
at least four inches thick. The reinforcing rod or mesh in the pad should
be attached to a bond wire.
DECK INSTALLATION
To be certain your deck can support your spa, you must know the
deck’s maximum load capacity. Consult a qualified building contractor
or structural engineer. To find the weight of your spa, its contents and
occupants, refer to the Spa Specification chart on back cover. This
weight per square foot must not exceed the structure’s rated capacity, or
serious structural damage could result.
INDOOR/BASEMENT INSTALLATION
Be aware of some special requirements if you place your spa indoors.
Water will accumulate around the spa, so flooring materials must
provide a good grip when wet. Proper drainage is essential to prevent
a build-up of water around the spa. When building a new room for the
spa it is recommended that a floor drain be installed. The humidity will
naturally increase with the spa indoors. Water may get into woodwork
and produce dry rot, mildew, or other problems. Check for airborne
moisture’s effects on exposed wood, paper, etc. in the room. To minimize
these effects, it is best to provide plenty of ventilation to the spa area. An
architect can help to determine if more ventilation must be installed.
CALDERA spas are equipped with a jet pump shroud to remove
excessive heat from the equipment compartment. Find this vent and be
sure the vent is not blocked by anything, including carpeting.
Your CALDERA dealer can help you with local information such as
zoning regulations and building codes.
WARNING: Please keep the area around your spa well ventilated
when it is installed indoors or in a confined area.
Inadequate ventilation around the spa could cause a build-up of a
higher-than-normal concentration of spa chemicals and/or bacterial
fragments. These dispersed spa chemicals and/or bacterial fragments
can be inhaled, and may result in breathing difficulties or lung damage
in certain people suffering from a compromised immune system
or respiratory infection. If you or other bathers are affected by this
condition, please seek medical attention as soon as possible.
In addition to the above, properly clean and maintain your spa as follows:
Follow all procedures in this owner’s manual and printed
instructions on all water care (chemical) products packaging.
Test the water regularly to ensure proper levels of sanitizers,
pH, and other water care requirements.
Drain, clean, and refill your spa with fresh water on a regular
schedule, and in accordance with this owner’s manual.
Clean the filter at least once per month.
Check to make sure you have proper circulation throughout
your spa water system.
Have spa users bathe before entering the spa water.
SPA LEVELING PREPARATION
Concrete sloped at 1.5 cm per 3 m (.5" per 10') is preferred so that rain
water and water spillover will run off and not puddle underneath the spa
(water under the spa for long periods of time may cause the wood to
deteriorate). Other options are brick, stepping stone, or blocks.
It is important to note that soft surfaces, even when stepping stones are
used to evenly distribute the weight of the spa, will have a tendency to
settle, thus resulting in an unleveled spa.
NOTE: Placing the spa on grass or dirt may increase the amount of
debris which is inadvertently brought into the spa water and may cause
harm to your equipment as well as the spa surface, which is not covered
under warranty.
Slope 1.5 cm per 3 m for proper drainage.
3 m
1.5 cm
Stepping stones or brick may settle
causing the spa to be unlevel.

Installation
SPA COVER INSTALLATION
1. Place the cover squarely on the spa.
2. Position the tie-down locks included with your cover on the
side of the spa so that they are easily reached by the cover
tie-down straps. Allow for about 1.5 - 2 cm (1/2” to 3/4”) slack
in the straps to make it easy to insert straps into locks and to
compensate for vinyl shrinkage in cold weather.
3. Attach the locks with the screws provided and insert the cover
tie-down straps into the locks.
NOTE: Keeping the cover in place any time the spa is not in use will
reduce the amount of time the heater operates, thereby minimizing
operating costs.
Your CALDERA spa has been thoroughly tested during the
manufacturing process to ensure reliability and long-term customer
satisfaction. A small amount of water may have remained in the
plumbing after testing and, as a result, may have spotted the spa shell
or the spa siding prior to delivery. Before filling the spa, wipe the spa
shell clean with a soft rag. The following instructions must be read and
followed exactly to ensure a successful start-up or refill.
DELIVERY ACCESS
NOTE: It may be necessary to allow for additional over-head clearance if the spa
will be rolled up or down an incline or moved up or down a short flight of stairs.
Use the information in the chart on the next page to determine the requirements
for access to your desired location. It may be necessary to remove a gate, part
of a fence, or other movable obstructions in order to roll the spa to its installation
site. About ten percent of the time, a crane is the only way to install the spa by
lifting it to its final destination.
If the spa has to be taken off of the cart to go over a wall (either because the
entry area is too narrow, the eaves are too low, the corner is too tight, or the
stairway is too steep), a crane will be required. Don’t be alarmed!
The crane has a truck-mounted boom which can fit right in your driveway. It is run
by a licensed and insured operator.
For a charge, the crane operator will
lift your spa over walls, buildings,
or any other obstruction and place
it as close to the installation site
as possible. The CALDERA spa
delivery personnel will supervise the
crane delivery and complete the spa
installation. Crane delivery typically
takes an average of 30 minutes to
complete.
NOTE: If your spa delivery requires
the use of a crane, you may be
required to pay for its services at the
completion of the delivery.

ServIce InformatIon
GENERAL INFORMATION
Your CALDERA spa has been designed to provide years of trouble-
free use. As with any appliance, problems may occasionally occur that
require the expertise of a qualified service person. Though such simple
repairs as resetting a RCD breaker, or resetting a high limit thermostat
may not require a service call, they may indicate that a more serious
condition exists. These conditions may require an experienced service
person. Before calling for service, please refer to the Troubleshooting
Guide. Always retain your original sales receipt for future reference.
RCD AND HIGH LIMIT THERMOSTAT
If your spa fails to operate at any time, first check the power supply to
the spa.
Check each of the RCD breakers in the subpanel. If a RCD has tripped,
reset it. If it will not reset, this may be an indication of a ground fault
(short circuit) within the electrical components. Contact an Authorized
Service Technician for a complete diagnosis.
If upon checking the RCD’s you find that they have not tripped, check
the house breaker panel and ensure the main breaker for the electrical
circuit supplying the spa has not tripped. If it has, this is an indication
that the circuit was either overloaded or a ground fault exists between
the breaker panel and the spa receptacle or subpanel. Contact a
qualified electrician.
If upon checking the main house breaker and spa RCD’s you find no
failures, check the high limit thermostat. To check it, simply turn off
power to the spa for 30 seconds. This will automatically reset the high
limit thermostat if it has tripped. If the spa energizes once you turn the
power back on, this indicates reduced water flow through the heating
system. Tripping of the high limit thermostat is normally a result of
one or a combination of these problems. 1) clogged filter cartridge(s),
2) blockage within the system plumbing, 3) a non-functioning heater
circulation pump, 4) power was not disconnected from the spa before it
was drained, 5) an air lock in the plumbing lines. (The Power Indicator
on the front of the spa’s control panel will also be blinking if the high limit
thermostat circuit has tripped.)
If the spa does not function after tripping and resetting the RCD’s or
resetting the high limit thermostat, then the problem should be referred
to an Authorized Service Technician. Refer to the Troubleshooting Guide
for additional service information.
HEATER AND INTEGRATED
PRESSURE SWITCH
Watkins Wellness unconditionally warrants the heater against any failure
that would require replacement. This warranty’s duration is equal to
the time period identified in the Heater Warranty. This warranty defines
unconditional as warranty coverage without exception provided that the
component has failed to operate properly within the spa’s system. This
means that conditions that would normally invalidate the limited
warranty, such as water chemistry damage, do not apply to the heater.
It is important to note that the heater is protected by both the heater high
limit thermostat circuit and the integrated pressure switch. The causes of
heater high limit tripping are discussed in the previous section.
If the spa is not heating, the red and green lights are blinking, but
the pump and light are operating, then the pressure switch may be
open. Opening of the pressure switch is normally a result of one or a
combination of these problems:
1. A clogged filter cartridge
2. Blockage within the system plumbing
3. Power was not disconnected to the spa before it was drained
4. An air lock in the plumbing lines
5. Circulation pump not properly working
Once the problem has been identified and corrected the pressure switch
will close which will energize the heater.
CIRCULATION PUMP AND
CIRCULATION PUMP THERMAL
CUT-OFF
The circulation pump is a dedicated, water cooled, energy efficient, quiet
pump that provides continuous filtration for the spa. Since the pump is
water cooled, it is equipped with a thermal cut-off to prevent the pump
from being damaged by running hot when water is not present.
Reset the circulation pump’s thermal cut-off by disconnecting power to
the spa and allowing the pump to cool.
Tripping of the thermal cut-off is normally the result of one or a
combination of these problems: 1) clogged filter cartridge(s), 2) blockage
within the system plumbing, 3) power was not disconnected to the spa
before it was drained, or 4) an air lock in the plumbing lines. Once the
problem has been identified and corrected the pump thermal cut-off will
be able to be reset which will allow it to operate normally.
MISCELLANEOUS SERVICE
INFORMATION
The control and high-limit thermostats are equipped with electronic
sensors that are connected to the spa’s plumbing. Never cut or kink the
wires that connect the sensors to the thermostats within the control box.
The jet pump is equipped with a thermal overload cutoff switch that is
designed to protect the pump from overheating. If the pump shuts itself
off in an older spa, it could indicate failure of the pump motor bearings. If
the pump shuts itself off in a new spa, it is usually the result of one or a
combination of the following factors:
Thermal overload: Although mass-produced, not all thermal overload
cutoffs are exactly the same. Some are more sensitive than others and
will shut the pump off at lower temperatures.
High temperature: All CALDERA spa models are equipped with a jet
pump shroud that vents the heat generated by the pump motor to the
outside of the equipment compartment, and back into the spa water. If
the vent is blocked by masonry, grass or debris, overheating of the jet
pump may occur. Once the pump motor has cooled sufficiently and any
blockage has been removed from the vent opening, the jet pump can
be restarted.
Friction: Sometimes the moving parts of a new pump are tight enough
to cause heat build-up due to friction. After a normal break-in period,
the pump will run cooler.
Improper wiring: If the spa is connected with an extension cord, and/
or the house wiring is undersized, the pump may starve for voltage and
therefore may draw more amperage and generate excessive heat.
If the pump is shutting down due to excessive heat, make sure the
equipment compartment has adequate ventilation. The air gap at the
bottom must not be blocked. Should your jet pump continue to shut off
after short periods of use, contact a qualified service technician.

ACTS INVALIDATING WARRANTY
The limited warranty is void if the CALDERA spa has been improperly
installed, subjected to alteration, misuse, or abuse, or if any repairs
on the spa are attempted by anyone other than an authorized
representative of Watkins Wellness. Alteration shall include any
component or plumbing change, electrical conversion, or the addition
of any non-approved sanitation or water purification device or heating
system which contributes to component or unit failure or unsafe
operating system. Misuse and abuse shall include any operation
of the spa other than in accordance with Watkins Wellness printed
instructions, or use of the spa in an application for which it is not
designed; specifically: use of the spa in a non-residential application;
damage caused by operation* of the spa at water temperatures outside
the range of 1.5°C (35°F) and 49°C (120°F); damage caused by a dirty,
clogged or calcified filter cartridge; damage to the spa surface caused
by the use of tri-chloro chlorine, BCDMH, misuse of chemical tablets
in a floater, acid, or any other spa chemicals or spa surface cleaners
which are not recommended by Watkins Wellness; damage caused by
allowing undissolved spa sanitizing chemicals to lie on the spa surface
(no spa surface material can withstand this kind of abuse); damage
to components or spa surface caused by improper water chemistry
maintenance; and damage to the spa surface caused by leaving the spa
uncovered while empty of water and in direct exposure to sunlight (this
may cause solar heating distress in warm weather regions). These are
considered abuses and may invalidate this warranty.
*Operation of the spa does not mean “use” of the spa! Watkins Wellness
does not recommend using the spa if the water temperature is above or
below the spa’s control panel temperature range.
DISCLAIMERS
Watkins Wellness shall not be liable for loss of use of the CALDERA
spa, or other incidental, consequential, special, indirect, or punitive
costs, expenses or damages, which may include but are not limited
to the removal of a permanent deck or other custom fixture, or the
necessity for crane removal. Any implied warranty shall have a duration
equal to the duration of the applicable limited warranty stated above.
Some states do not allow limitations on how long an implied warranty
lasts. Under no circumstances shall Watkins Wellness or any of its
representatives be held liable for injury to any person or damage to any
property, however arising.
Some states do not allow the exclusion or limitation of incidental or
consequential damages, so the above limitations may not apply to you.
