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.

Watkins Wellness congratulates you on your decision to enjoy the finest spa available... Welcome to the

growing family of Caldera® Spa owners.

NOTE: This is an example. Your spa’s

label will contain different information.

IMPORTANT SAFETY

INSTRUCTIONS

(READ AND FOLLOW ALL

INSTRUCTIONS)

AVOIDING THE RISK TO CHILDREN

DANGER - RISK OF CHILD DROWNING

• 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

product 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 metal 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 your

child 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 the 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

Risk of electrocution

• Connect only to a grounded source. The spa must be connected

to a Ground Fault Circuit Interrupter (GFCI). Watkins Wellness

does not supply a GFCI with the spa. Watkins recommends

the GFCI be attached to the end of the spa’s electrical cord.

Additionally, the GFCI should be VDE listed and approved by a

licensed electrician complying to all local codes using 16 amps

with a maximum 10 milliamp trip. Contact your authorized spa

dealer.

WARNING

• Always test the Ground Fault Circuit Interrupter (GFCI) before

each use of the spa. If the GFCI does not perform properly, a

ground current is flowing indicating the possibility of electric

shock. Disconnect power to the spa until the fault has been

identified and corrected.

• 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.

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.

• A ground terminal (pressure wire connector) is provided on the

control box inside the unit to permit connection of a minimum

No. 8.4 mm² (8 AWG) 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 (five

feet) of the unit as needed to comply with local requirements. If

the spa is located on a reinforced concrete pad, the reinforced

steel should also be bonded to the ground terminal.

• Your spa must be supplied by a ground fault circuit interrupter

- residual current device (RCD) - with a tripping rating not

exceeding 30 mA in an electrical subpanel.

DANGER: RISK OF ELECTRICAL SHOCK

• Install at least 1.5 m (5 feet) from all metal surfaces. A spa may

be installed within 1.5 m (5 feet) of a metal surface if each metal

surface is permanently connected by a minimum No. 6 mm2

(10 AWG) 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 feet) 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.

DO:

• Be sure your spa is connected to the power supply correctly - use

a licensed 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.

DON’T:

• Use the spa with the equipment compartment door removed.

• Place electrical appliances within 1.5 m (5 feet) 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.

Safety Information

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:

3.0-5.0 ppm

Total Alkalinity:

40-120 ppm

Water pH:

7.2-7.8

Calcium Hardness:

50-150 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. 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 (100°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.

2Safety Information

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 Monarch® 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 MONARCH Stain & Scale

Defense.)

3. Keep all cleaners out of the reach of children and use care when

applying.

Safety Information

InStallatIon

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(s) 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 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.

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 1/2” 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.

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! Your spa must be supplied by

a ground fault circuit interrupter - residual current device (RCD) - with a

tripping rating not exceeding 30 mA in an electrical subpanel.

VACANZA 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 MARINO, CAPITOLO, CELIO and AVENTINE spas require a 16

amp, single phase, 230 volt, three wire service (one line, one neutral,

one ground).

The AVENTINE can be converted to a 20 amp service allowing the

high speed jet pump to operate simultaneously with the heater. A

CALDERA Spa Technician must reconfigure spa using the soft jumpers

to allow the heater to run concurrent with jet pump.

The PALATINO spa requires a 20 amp single phase, 230 volt,

three wire service (one line, one neutral, one ground) found below.

Additionally, one main disconnect switch with at least 3 mm 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 feet) away.

CONDUIT INSTALLATION INSTRUCTIONS

1. To connect the electrical service, first remove the screws from the

equipment compartment door. Carefully pull the door panel down

and away in order to remove it completely 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. Route the electrical conduit through the access opening of the spa.

4. Connect the supply conduit to the control box and connect the

wiring as detailed on the next page, or on the wiring diagram label

on the inside of the control box cover.

WARNING: Removing or bypassing any GFCI 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

VACANZA spa, it is essential that you understand and apply these

installation requirements. Your VACANZA 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.

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 MONARCH 5-way Test Strips Available.

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: Watkins Wellness does not recommend that the

spa be filled with “softened” water, as this may damage the spa’s

equipment.

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 cold water temperature

below 10º C (50º F)! Tripping of the high-limit thermostat may

result causing your spa to stop functioning.

Use your spa after filling until all of the steps listed below START-UP

are completed!

Add chlorine if treating your spa with polyhexamethylene biguanide

(Biguanide, PHMB, eg. BaquaSpa®) sanitizer.

START-UP AND REFILL PROCEDURES

START-UP

Your VACANZA series 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.

1. ENSURE that the drain is closed and remove the filter compartment

cover, skimmer basket, weir, and filter. Then insert the end of a

garden hose into the filter canister and begin filling the spa. The

water level of your VACANZA series spa should be maintained at

a level one inch above the highest jet in the spa. Reinstall the filter

and then the skimmer basket, and weir once the spa is filled.

IMPORTANT: Watkins Wellness does not recommend that the

spa be filled with “softened” water, as this may damage the spa’s

equipment.

2. AFTER the spa has been filled with water and the equipment

compartment door is secured, power must be applied to the spa.

3. TO CHECK THE OPERATION OF THE JET SYSTEM and to

purge any remaining air from the heating system, push the “JETS”

button on the control panel three times (twice for CAPITOLO,

CELIO & AVENTINE models) to run the jet pump(s) on high speed

for one minute. Once the jet system is fully operational (as indicated

by strong, non-surging jets), priming of the spa is complete. 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 in the back of this manual.

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.

5. USING A TEST STRIP AND APPLICABLE CHEMICALS adjust

Total Alkalinity (TA) to 40-120 ppm, Calcium Hardness (CH) to

50-150 ppm, then spa water pH to between 7.2 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.

IMPORTANT: Activate the Clean cycle (Press "MODE



" or

"MODE▼" until CLEAN is displayed then press "ON



" to activate

clean cycle) before adding spa water chemicals directly into the filter

compartment. Make sure all diverter valves are set to the middle

position.

6. ADD Metal remover if metals are in water. Wait 24 hours before

adding FROG.

7. SUPERCHLORINATE THE SPA WATER by adding 1½ teaspoons

of MONARCH chlorine (sodium dichlor) per 950 liters (250 gallons)

of spa water, then activate the Clean cycle by pressing "MODE



or"MODE▼"untilCLEANisdisplayedthenpressthe"ON



button .

8. TEST THE SPA WATER FOR CHLORINE RESIDUAL. If the

residual is between 3 and 5 ppm on the test strips, go on to the

next step. If the residual is less than 3 ppm add 1 teaspoon of

MONARCH chlorine (sodium dichlor), activate the Clean cycle, and

then retest. Repeat if necessary.

IMPORTANT: For Canada, if you are only using the bromine

cartridge, your bromine levels should be between 3.0 - 5.0 ppm.

9. IF USING FROG INSTALL FROG bromine and mineral

cartridges. Dial the mineral cartridge to setting 6 and snap into the

top space of the cartridge holder. Dial the bromine cartridge to setting

3 and snap into the bottom space of the cartridge holder.

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: Each time the spa is filled with water, you must

remove and reinstall the FROG cap, even if you are not replacing

the cartridge, in order to properly prime the jet pumps.

10. RECHECK the Total Alkalinity (TA) 40-120 ppm, Calcium Hardness

(CH) 50-150 ppm, then spa water pH at 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 bromine level remains between 1 and 2 ppm or chlorine level

remains between 3 and 5 ppm.

OPERATION NOTE:

1. Your spa is equipped with a ten-minute timer delay on the heating/

tranquil mode. Whenever the jet pump has been turned off (and

a three-degree temperature drop has occurred) or the temperature

control has been turned up, it will take ten minutes before the low

speed of the jet pump and heater become activated. Always push the

“JETS” button to turn off the jet pump when exiting the spa.

2. The spa controller has an automatic one-hour “time-out” feature

should the high speed jet mode be left on inadvertently. After one

hour of continuous operation, the controller will automatically

return to the maintenance/heating mode.

3. The spa controller also has a six-hour “time-out” feature should

the light be left on inadvertently. After six hours of continuous

operation, the controller will automatically turn the light off.

PRIMING THE PUMP(S)

Upon filling or refilling the spa, if a pump is operating and water is not

flowing from any of its jets, the pump may not be properly primed.

To correct, refer to the illustration below and perform the following

procedures:

• Turn off power to the spa at the breaker and remove the equipment

compartment door.

• Loosen the union on the top of the pump(s) to allow the air to

escape. When water is present, hand-tighten the union.

• Turn power back on, activate the pump and check to make sure

union is tight enough to keep it from leaking. Re-install equipment

door.

NOTE: Equipment compartment illustrated below will vary

depending on spa model.

IMPORTANT

THE DRAIN CAP AND UNION FITTINGS IN THE EQUIPMENT COMPARTMENT

MAY LOOSEN DURING TRANSPORTATION. TO AVOID LEAKS, PLEASE

CHECK TO MAKE SURE THESE ARE HAND-TIGHT

PRIOR TO FILLING YOUR SPA.

Operating Instructions

SLEEP MODE

The Sleep Mode operation is a feature that minimizes pump operation

during quiet evening hours. For example, if Filter Cycle 1 (F1) is set to

activate at 8:00 a.m., by default, Filter Cycle 2 (F2) will activate at 8:00

p.m. (12 hours later). During 8:00 p.m. to 8:00 a.m., if the spa should call

for heat, the pump and heater will activate to heat the spa under normal

temperature demand. However, when in Sleep Mode, should the spa call

for heat, the pump and heater

will be suspended after Filter Cycle 2 (F2)

until the activation of Filter Cycle 1 (F1), at 8:00 a.m. to minimize pump

activation during quiet evening hours.

Important: Power-up of the spa starts the F1 sequence. In order for the

sleep mode to work in the evening hours, the spa must be powered up in

the early morning hours. The Sleep Mode will always be active the 6-12

hours between the end of (F2) and the beginning of (F1) depending on

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.

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.

Your program will depend on your water’s mineral content, how often you

use your spa, and how many people use it.

WATER QUALITY CHART

PARAMETER TARGET MIN - "OK" RANGE - MAX

pH 7.4 7.2 7.8

ALKALINITY 80 ppm 40 ppm 120 ppm

HARDNESS 100 ppm 50 ppm 150 ppm

CHLORINE 3 ppm 1 ppm 5 ppm

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 (other than FROG cartridges),

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

50 - 150 ppm. If the CH level is too high, lower it with the

VANISHING ACT calcium remover 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 water’s 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 MONARCH pH/Alkalinity Up

(sodium hydrogen carbonate). To lower the TA, use MONARCH

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 MONARCH pH/Alkalinity Down (sodium

bisulfate). To raise the pH level, use MONARCH 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

MONARCH 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 3.0-5.0 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 recommends the following sanitizer:

• FROG sanitizing system (mineral and bromine)

Watkins also approves the following sanitizers:

• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)

• 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.

FROG WATER CARE SYSTEM

The FROG Water Care system is comprised of the following two

products:

THE FROG MINERAL CARTRIDGE. This cartridge introduces minerals

into the spa water, inhibiting bacteria growth.

THE FROG BROMINE CARTRIDGE (BCDMH). The only recommended

sanitizer that will work in conjunction with the FROG Mineral cartridge.

It is important that in addition to regularly testing and balancing your

spa water, a weekly "shock treatment" is required. The shock treatment

quickly destroys any remaining contaminants while revitalizing the

bromine in the water.

To weekly “shock treat” your spa, we recommend that you use

MONARCH MPS Plus The following optional products can be used in

conjunction with the FROG Water Care system:

MONARCH MPS PLUS NON-CHLORINE SHOCK (MPS/

Monopersulfate) is an oxidizing chemical used to prevent the buildup

of contaminants, maximize sanitizer efficiency, and improve water

clarity. When used in conjunction with the FROG system it oxidizes

particulates in the spa water.

IMPORTANT NOTE: MONARCH MPS Plus is an oxidizer, not a

sanitizer.

MONARCH CORONA DISCHARGE (CD) OZONE is a high output

ozone system and is the only ozone purification system approved for

installation in your CALDERA Spa. The MONARCH ozone system

utilizes CD technology to produce a higher concentration of ozone

than is produced by a competing chip style CD or ultraviolet light

ozone systems.

NOTE: Refer to the Start-Up instructions on page 4 of your FROG

owner's manual for start-up and operation instructions. The owner's

manual can be found with your FROG starter kit.

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 or time, such as a whole afternoon or evening,

additional sanitizer will be needed.

NOTE: The FROG Mineral Cartridge is not approved for use in

Canada.

NOTE: For Canada, if you are only using the bromine cartridge, your

bromine levels should be between 3.0 - 5.0 ppm.

FROG CARTRIDGE REPLACEMENT

INSTRUCTIONS

The FROG bromine cartridge should be replaced every 2-4 weeks,

depending on User Load. The FROG mineral cartridge should be

replaced every 4 months. When replacing the mineral cartridge, it is

highly recommended that the spa be drained and refilled at the same

time. After refilling the spa with water, balance the Total Alkalinity (TA),

Calcium Hardness (CH) and pH to the recommended levels. Shock the

spa by adding MONARCH MPS Plus non-chlorine shock or sodium

dichlor (chlorine).

To replace FROG

cartridges, follow these steps:

1. Turn off power to the spa.

2. Unscrew FROG cap on top edge of spa.

3. Turn handle counter-clockwise.

4. Lift cartridge holder up and out of spa.

5. Remove and discard old cartridges.

6. Turn top cap of new Mineral cartridge to setting #6 (evaluate water

in 1 week and adjust as necessary).

7. Turn top cap of new bromine cartridge to setting #6 (measure

bromine with bromine Test Strip in 1 week and adjust as necessary).

8. Snap bromine cartridge into the bottom of holder and snap mineral

cartridge into the top.

IMPORTANT: It is important that the bromine cartridge is on

the bottom; otherwise, the bromine cartridge could dispense

prematurely.

9. Reinstall cartridge holder into spa, push down, and twist clockwise.

10. Replace FROG cap.

11. Reconnect power to the spa.

IMPORTANT NOTE: Adjust bromine cartridge setting down by one

setting each day until a residual of 1.0 - 2.0 ppm level of bromine is

established.

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.

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) or shock

(4tbs mps/950 liters) 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!

MANUAL CHLORINE (SODIUM DICHLOR)

Watkins Wellness recommends the use of MONARCH

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, 3.0-5.0 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.

MONARCH OZONE MAINTENANCE

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.

Use household bleach (liquid sodium hypochlorite).

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

of 80°F (27°C)

IMPORTANT: Spa water oxidizers such as sodium dichlor (chlorine)

maintain their level of effectiveness substantially longer in warm water

80°F

(27°C)

than in hot water 101°F to 104°F (38°C - 40°C).

2. Adjust the pH as required. Sanitize the water by following the shock

procedures.

Water Quality and Maintenance

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.

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.

WATER TERMINOLOGY

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.

Calcium Hardness: The amount of dissolved calcium in the spa water.

This should be approximately 50 -150 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 the non-chlorine oxidizer used with the

FRESHWATERAg+ silver ion purification system. Not a sanitizer.

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.

Water Quality and Maintenance

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.

DRAIN & REFILL INSTRUCTIONS

IMPORTANT: It is NOT recommended to refill your spa when the ambient

temperature goes below 10° C (50° F).

1. Disconnect the spa from the power supply by tripping both of the GFCI breakers

located in the subpanel. Unplug power cord for 115V models.

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 (to avoid flooding of the foundation surrounding the spa) and

route the outlet of the hose to an appropriate draining area. 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 CALDERA spa models will drain to the bottom of

the suction fitting, use vacuum side of shop vac to remove remaining

water. Any water remaining within the plumbing or equipment after

draining will only need to be removed if the spa is being winterized.

4. When empty, inspect the spa shell and clean as required. (Follow the

Care of the Exterior instructions.)

5. Close the drain valve by reinstall the drain cap.

6. Install new filter or clean existing with MONARCH filter cleaner.

7. Refill the spa through the filter compartment using the CLEAN

SCREEN pre-filter

IMPORTANT: Refill water temperature must be between 10º -21º C

(50° - 70° F) to avoid high-limit tripping.

8. Follow the Quick Start-Up instructions on page 14.

COLD WATER REFILL

Should it be necessary to drain and refill your spa in temperatures

below 10° C (50° F), the spa may go into a High Limit Protection mode

(causing your spa to stop functioning) if the tap water is below 10° C

(50° F). Blending warm water with the cold tap water so it exceeds 10°

C (50° F) during the refilling process will prevent the spa

from going into

the High Limit Protection mode if that is an option for you.

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 or 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 or 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 CALDERA dealer to perform this service

1. Drain your spa following the Drain & Refill Instructions. Open

waterfall valve.

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 20 liters 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. Replace the main drain cap.

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!

6. 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.

7. 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.

8. 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 and Refill Procedures in the Operating

Instructions 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 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 and Refill Procedures in the Operating Instructions

section of the Owner’s Manual.

IMPORTANT: Always keep spa covered when not in use, whether it is

empty or full.

FILTER SYSTEM

The filter lid on the spa is NOT designed to support heavy weight loads

and should not be used as a seat. In extreme cases, the lid could crack

and break. This occurrence is considered abuse and is not covered under

the warranty.

CALDERA spas are equipped with one filter cartridge, sized to meet the

needs of the jet pump system.

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 permits the hydrotherapy

system to function properly and also allows 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 and poor jet

performance.

WARNING: To reduce the risk of injury to persons using the spa, DO

NOT remove the suction fittings (filter standpipes) located in the filter

compartment and do not sit on the filter lid, in extreme cases the lid could

crack and break. This occurrence is considered abuse and is not covered

under warranty.

SECONDARY SUCTION SCREEN

Located in the foot well of your spa are three secondary suction screens.

The screen is used as a filter to prevent dirt from circulating through the

system.

WARNING: Do not use the spa with the suction screens removed.

FILTER CARTRIDGES REMOVAL &

CLEANING FOR PALATINO, MARINO,

CAPITOLO & CELIO MODELS.

1. Disconnect the spa from the power supply by turning the power to

the spa OFF.

2. Remove any floating items from within the filter compartment.

3. Turn the filter retainer handle (located on the top of the filter cartridge)

counterclockwise until the retainer can be removed from the filter

standpipe.

4. Remove the filter retainer, cover and cartridge.

SERVICE NOTE: Never remove the filter standpipe when debris is present

in the filter compartment. Debris may find its way into the internal plumbing

which may result in blockage. NEVER REMOVE SUCTION FITTINGS!

5. Always clean the filter using a filter degreaser, such as

MONARCH Filter Cleaner, 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.

6. To reinstall the filter cartridge, reverse the order of steps in which it

was removed. Do not overtighten.

WARNING: Do not use the spa with the filter cartridges, or filter

standpipe(s) removed!

1. Turn the power to the spa OFF, then proceed as follows:

2. Push down slightly and turn filter basket counterclockwise to unlock,

then pull the basket and weir out.

3. Carefully pull up the filter cartridge and bring it out of the spa.

4. Rinse cartridge using a garden hose. Rotate and separate filter

pleats while spraying water to remove all debris possible. Let the

filter dry and then look for calcium deposits (scaling) or an oil film. If

you find these, you will need to deep clean your filter cartridge with

a “spa filter cleaning” solution to break down and remove mineral

deposits and oils.

5. Install filter then replace basket and weir by inserting and rotating

clockwise to lock into position.

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 spa use.

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 (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

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 Stain & Scale Defense.)

3. Keep all cleaners out of the reach of children and use care when

applying.

CARE OF THE ECOTECH CABINET

The ECOTECH cabinet consists of rigid polymers that combine the durability of

plastic, with the beauty of wood.

Cleaning your ECOTECH cabinet is as easy as spraying the cabinet with a mild

soap and water solution to remove any stains and residue.

CARE OF THE SPA COVER

WARNING: The cover is a manual safety cover that meets or

exceeds all prevailing requirements of ASTM 1346-91 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 the cover from the spa and gently lean it against a wall or

fence.

2. With a garden hose, spray the cover to loosen and rinse away dirt

or debris.

3. Using a large sponge and/or a soft bristle brush, and using a very mild

soap solution (one teaspoon dishwashing liquid with two 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 (use no soap),

and wipe it clean with a dry rag.

6. To condition the cover after cleaning, apply MONARCH Cover

Shield to protect the cover.

IMPORTANT: 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.

DO:

Remove snow buildup to avoid breakage of the foam core from the

additional weight of the snow.

Lock cover lock straps to secure the cover when the spa is not in

use.

DON'T:

Drag or lift the spa cover using either the flaps, or the cover lock

straps.

Walk, stand, or sit on the cover.

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.

Use any lifting mechanisms, chemicals, or cleaners except those

recommended by Watkins Wellness, or its Authorized Sales and

Service Dealer.

Spa Care and Maintenance

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 GFCI switch or breaker, high limit thermostat, or pressure

switch, or replacing a light bulb 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.

NOTE: Always retain your original sales receipt for future reference.

GFCI AND HIGH LIMIT THERMOSTAT

If your spa fails to operate at any time, the following items should be

checked:

1. Check the power supply to the spa.

2. Check the GFCI (located at the end of the cord in standard models or in the

electrical subpanel in 30 amp converted models) and see if it has tripped. If a

GFCI 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.

3. If, upon checking the GFCI you find it has 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 either the circuit was overloaded or a

ground fault exists between the breaker panel and the spa receptacle. Contact a

qualified electrician.

4. If, upon checking the main house breaker, you find no failures, the heater high-

limit thermostat should be checked. Tripping of the heater high-limit thermostat is

normally a result of one or a combination of any of these problems: 1) blockage

within the system plumbing, 2) switch malfunction in the heater circuit, or 3) the low

speed mode of the jet pump is not functioning.

5. If the heater high-limit has tripped, the control panel display will display - - - -. Reset

the heater high-limit by allowing the water to cool and disconnecting power to the

spa for at least thirty seconds. If the heater high-limit continues to trip, contact an

Authorized Service Technician for a complete diagnosis.

If the spa does not function and the GFCI or GFCI breaker and heater

high-limit have not tripped, then the problem should be referred to an

Authorized Service Technician. Refer to the Troubleshooting Guide for

additional service information.

MISCELLANEOUS SERVICE

INFORMATION

The jet pump is equipped with an overload cut-off switch, which is

designed to protect the pump from overheating. If the pump shuts itself

off in a new spa, it is usually the result of one, or a combination of, the

following factors:

High Temperature: During the summer months, especially in warmer

climates, the ambient temperature contributes to excessively high

temperatures within the equipment compartment.

Improper House Wiring: If the spa is not connected to a dedicated

circuit, or is connected to an extension cord, or the house wiring is

undersized, the pump may starve for voltage and therefore may draw

more amperage and generate excessive heat. This will often cause the

circuit breaker to trip repeatedly.

IMPORTANT:

1. If the pump is shutting down due to excessive heat, make sure the equipment

compartment has adequate ventilation. The air gap at the bottom and the jet pump

vent at the bottom left corner must not be blocked. Should your jet pump continue to

shut off after short periods of use, contact a qualified service technician.

2. The VACANZAZ spa is equipped with a safety suction spring

valve which will break the prime of the jet pump if both suction

fittings are obstructed.

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 byanyone 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 1.7°C and 49°C; 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 VACANZA

series spa or other incidental or consequential costs, expenses or

damages, which may include but are not limited to, the removal of a

permanent deck or other custom fixture. Any implied warranty shall

have a duration equal to the duration of the applicable warranty stated

above. 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.
