Repairing Refrigerant Leaks
WARNING
• If the refrigerant leaks, turn off the air
conditioner and any combustible heating
devices, ventilate the room and call your
dealer immediately. Refrigerant is both
toxic and ammable.
DO NOT
use the
air conditioner until the leak is repaired.
• When the air conditioner is installed in a
small room, measures must be taken to
prevent the refrigerant concentration
from exceeding the safety limit in the
event of refrigerant leakage.
Concentrated refrigerant causes a severe
health and safety threat.
Refrigerant Leak Detection System
• In the event of a refrigerant leak, the LCD
screen will display “EC” and the LED
indicator light will ash.

the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns off the
compressor. The unit will resume operating when the temperature fluctuates
again.
The indoor unit
emits white mist
In humid regions, a large temperature difference between the room’s air and
the conditioned air can cause white mist.
Both the indoor
and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
The indoor unit
makes noises
A squeaking sound is heard when the system is OFF or in COOL mode. The
noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Troubleshooting 5
Both the indoor
unit and outdoor
unit make noises
A low hissing sound may occur during operation. This is normal and is caused
by refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard when the system starts, has just stopped
running or is defrosting. This noise is normal and is caused by the refrigerant
gas stopping or changing direction.
The outdoor unit
makes noises
The unit will make different sounds based on its current operating mode.
Problem Possible Causes
Page 17
Dust is emitted from
either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of non-use, which
will be emitted when the unit is turned on. This can be mitigated by covering
the unit during long periods of inactivity.
The unit emits a
bad odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s lters have become moldy and should be cleaned.

A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Troubleshooting 5
Both the indoor
unit and outdoor
unit make noises
A low hissing sound may occur during operation. This is normal and is caused
by refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard when the system starts, has just stopped
running or is defrosting. This noise is normal and is caused by the refrigerant
gas stopping or changing direction.
The outdoor unit
makes noises
The unit will make different sounds based on its current operating mode.
Problem Possible Causes
Page 17
Dust is emitted from
either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of non-use, which
will be emitted when the unit is turned on. This can be mitigated by covering
the unit during long periods of inactivity.
The unit emits a
bad odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s lters have become moldy and should be cleaned.
The fan of the
outdoor unit
does not operate
During operation, the fan speed is controlled to optimize product operation.

Outdoor Unit Installation
Outdoor Unit Installation Instructions
Step 1: Select installation location.
The outdoor unit should be installed in the
location that meets the following requirements:
o Place the outdoor unit as close to the indoor
unit as possible.
o Ensure that there is enough room for
installation and maintenance.
o The air inlet and outlet must not be
obstructed or exposed to strong wind.
o Ensure the location of the unit will not be
subject to snowdrifts, accumulation of leaves
or other seasonal debris. If possible, provide
an awning for the unit. Ensure the awning
does not obstruct airow.
o The installation area must be dry and well
ventilated.
o There must be enough room to install the
connecting pipes and cables and to access
them for maintenance.
o The area must be free of combustible gases
and chemicals.
o The pipe length between the outdoor and
indoor unit may not exceed the maximum
allowable pipe length.
o If possible, DO NOT install the unit where it
is exposed to direct sunlight.
o If possible, make sure the unit is located far
away from your neighbors’ property so that
the noise from the unit will not disturb them.
o If the location is exposed to strong winds (for
example: near a seaside), the unit must be
placed against the wall to shelter it from the
wind. If necessary, use an awning.
(See Fig. 9.1 & 9.2)
o Install the indoor and outdoor units, cables
and wires at least 1 meter from televisions or
radios to prevent static or image distortion.

Refrigerant Piping Connection
Safety Precautions
• All eld piping must be completed by a
licensed technician and must comply with
the local and national regulations.
• When the air conditioner is installed in a
small room, measures must be taken to
prevent the refrigerant concentration in
the room from exceeding the safety limit
in the event of refrigerant leakage. If the
refrigerant leaks and its concentration
exceeds its proper limit, hazards due to
lack of oxygen may result.
• When installing the refrigeration system,
ensure that air, dust, moisture or foreign
substances do not enter the refrigerant
circuit. Contamination in the system may
cause poor operating capacity, high
pressure in the refrigeration cycle,
explosion or injury.
• Ventilate the area immediately if there is
refrigerant leakage during the installation.
Leaked refrigerant gas is both toxic and
ammable. Ensure there is no refrigerant
leakage after completing the installation
work.
11
Refrigerant Piping Connection Instructions
• The branching pipe must be installed
horizontally. An angle of more than 10°
may cause malfunction.
• DO NOT install the connecting pipe until
both indoor and outdoor units have been
installed.
• Insulate both the gas and liquid piping to
prevent water leakage.
Step1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and are them properly. This will
ensure efcient operation and minimize the
need for future maintenance.
1.
Measure the distance between the indoor
and outdoor units.
2.
Using a pipe cutter, cut the pipe a little
longer than the measured distance.
DO NOT deform pipe while cutting. Be extra
careful not to damage, dent, or deform the
pipe while cutting. This will drastically reduce
the heating efciency of the unit.
1.Make sure that the pipe is cut at a perfect 90°
angle. Refer to Fig. 7.1 for examples of bad cuts
Oblique Rough Warped
90°

Step 2: Remove burrs.
Burrs can affect the air-tight seal of refrigerant
piping connection. They must be completely
removed.
1. Hold the pipe at a downward angle to
prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove
all burrs from the cut section of the pipe.

modify the length of the power
cord or use an extension cord.
• Connect the outdoor wires before
connecting the indoor wires.
• Make sure you ground the unit. The
grounding wire should be away from gas
pipes, water pipes, lightning rods,
telephone or other grounding wires.
Improper grounding may cause electrical
shock.
• DO NOT connect the unit with the power
source until all wiring and piping is
completed.
• Make sure that you do not cross your
electrical wiring with your signal wiring, as
this can cause distortion and interference.

Note On Adding Refrigerant
CAUTION
• Refrigerant charging must be performed after wiring, vacuuming, and the leak testing.
• DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system.
Doing so can damage the unit or impact it’s functioning.
• Charging with unsuitable substances may cause explosions or accidents. Ensure that the
appropriate refrigerant is used.
• Refrigerant containers must be opened slowly. Always use protective gear when charging the
system.
• For the R290 or R32 refrigerant model, make sure the condtions within the area have been
made safe by control of ammable material when the refrigerant added into air conditioner.
• DO NOT mix refrigerants types.

l
the charge size is in accordance with the room size within which the refrigerant containing
parts are installed;
the ventilation machinery and outlets are operating adequately and are not obstructed;
if an indirect refrigerating circuit is being used, the secondary circuits shall be checked
for the presence of refrigerant; marking to the equipment continues to be visible and
legible.
Repair and maintenance to electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise safety, then no
electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault
cannot be corrected immediately but it is necessary to continue operation, and adequate
temporary solution shall be used. This shall be reported to the owner of the equipment so all
parties are advised.
Initial safety checks shall include:
that capacitors are discharged: this shall be done in a safe manner to avoid possibility of
sparking
that there no live electrical components and wiring are exposed while charging, recovering
or purging the system;
that there is continuity of earth bonding.
10.1 During repairs to sealed components, all electrical supplies shall be disconnected from the
equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely
necessary to have an electrical supply to equipment during servicing, then a permanently
operating form of leak detection shall be located at the most critical point to warn of a
potentially hazardous situation.
10.2 Particular attention shall be paid to the following to ensure that by working on electrical
components, the casing is not altered in such a way that the level of protection is affected.
,
This shall include damage to cables, excessive number of connections, terminals not made
to original specication, damage to seals, incorrect tting of glands, etc.
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded such that they no longer serve
the purpose of preventing the ingress of ammable atmospheres. Replacement parts shall
be in accordance with the manufacturer s specications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection
equipment. Instrinsically safe components do not have to be isolated prior to working on them.
11. Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring
that this will not exceed the permissible voltage and current permitted for the equipment in
use. Intrinscially safe components are the only types that can be worked on while live in the
presence of a ammable atmosphere. The test apparatus shall be at the correct rating.
Replace components only with parts specied by the manufacturer. Other parts may result
in the ignition of refrigerant in the atmosphere from a leak.

The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be
ushed with OFN to render the unit safe. This process may need to be repeated several times.
Compressed air or oxygen shall not be used for this task.
12. Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp
edges or any other adverse environmental effects. The check shall also take into account the
effects of aging or continual vibration from sources such as compressors or fans.

15. Removal and evacuation
When breaking into the refrigerant circuit to make repairs of for any other purpose
conventional procedures shall be used, However, it is important that best practice is followed
since ammability is a consideration. The following procedure shall be adhered to:
remove refrigerant;
purge the circuit with inert gas;
evacuate;
purge again with inert gas;
open the circuit by cutting or brazing.
13. Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the searching for or
detection of refrigerant leaks. A halide torch(or any other detector using a naked ame)
shall not be used.
14. Leak detection methods
The following leak detection methods are deemed acceptable for systems containing ammable
refrigerants. Electronic leak detectors shall be used to detect ammable refrigerants, but the
sensitivity may not be adequate, or may need re-calibration.(Detection equipment shall be
calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition
and is suitable for the refrigerant. Leak detection equipment shall be set at a percentage of the
LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate
percentage of gas (25% maximum) is conrmed. Leak detection uids are suitable for use with
most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine
may react with the refrigerant and corrode the copper pipe-work.
If a leak is suspected ,all naked ames shall be removed or extinguished. If a leakage of refrigernat
is found which requires brazing, all of the refrigerant shall be recovered from the system, or
isolated(by means of shut off valves) in a part of the system remote from the leak . Oxygen free
nitrogen(OFN) shall then be purged through the system both before and during the brazing process.
Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to
ll until the working pressure is achieved, then venting to atmosphere, and nally pulling down
to a vacuum. This process shall be repeated until no refrigerant is within the system.
When the nal OFN charge is used, the system shall be vented down to atmospheric pressure
to enable work to take place. This operation is absolutely vital if brazing operations on the
pipe-work are to take place.
Ensure that the outlet for the vacuum pump is not closed to any ignition sources and there
is ventilation available.

9. Checks to electrical devices
10. Repairs to sealed components
marking and signs that are illegible shall be corrected;
refrigeration pipe or components are installed in a position where they are unlikely to be
exposed to any substance which may corrode refrigerant containing components, unless
the components are constructed of materials which are inherently resistant to being
corroded or are suitably protected against being so corroded.
l
l
l
the charge size is in accordance with the room size within which the refrigerant containing
parts are installed;
the ventilation machinery and outlets are operating adequately and are not obstructed;
if an indirect refrigerating circuit is being used, the secondary circuits shall be checked
for the presence of refrigerant; marking to the equipment continues to be visible and
legible.
Repair and maintenance to electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise safety, then no
electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault
cannot be corrected immediately but it is necessary to continue operation, and adequate
temporary solution shall be used. This shall be reported to the owner of the equipment so all
parties are advised.
Initial safety checks shall include:
that capacitors are discharged: this shall be done in a safe manner to avoid possibility of
sparking
that there no live electrical components and wiring are exposed while charging, recovering
or purging the system;
that there is continuity of earth bonding.
10.1 During repairs to sealed components, all electrical supplies shall be disconnected from the
equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely
necessary to have an electrical supply to equipment during servicing, then a permanently
operating form of leak detection shall be located at the most critical point to warn of a
potentially hazardous situation.
10.2 Particular attention shall be paid to the following to ensure that by working on electrical
components, the casing is not altered in such a way that the level of protection is affected.
,
This shall include damage to cables, excessive number of connections, terminals not made
to original specication, damage to seals, incorrect tting of glands, etc.
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded such that they no longer serve
the purpose of preventing the ingress of ammable atmospheres. Replacement parts shall
be in accordance with the manufacturer s specications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection
equipment. Instrinsically safe components do not have to be isolated prior to working on them.
11. Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring
that this will not exceed the permissible voltage and current permitted for the equipment in
use. Intrinscially safe components are the only types that can be worked on while live in the
presence of a ammable atmosphere. The test apparatus shall be at the correct rating.
Replace components only with parts specied by the manufacturer. Other parts may result
in the ignition of refrigerant in the atmosphere from a leak.

17. Decommissioning
Before carrying out this procedure, it is essential that the technician is completely familiar
with the equipment and all its detail. It is recommended good practice that all refrigerants
are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall
be taken.
In case analysis is required prior to re-use of reclaimed refrigerant. It is essential that
electrical power is available before the task is commenced.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically
c) Before attempting the procedure ensure that:
mechanical handling equipment is available, if required, for handling refrigerant cylinders;
all personal protetive equipment is available and being used correctly;
the recovery process is supervised at all times by a competent person;
recovery equipment and cylinders conform to the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from
various parts of the system.
16. Charging procedures
In addition to conventional charging procedures, the following requirements shall be followed:
Ensure that contamination of different refrigerants does not occur when using charging
equipment. Hoses or lines shall be as short as possible to minimize the amount of
refrigerant contained in them.
Cylinders shall be kept upright.
Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
Label the system when charging is complete(if not already).
Extreme care shall be taken not to overll the refrigeration system.
Prior to recharging the system it shall be pressure tested with OFN. The system shall be
leak tested on completion of charging but prior to commissioning. A follow up leak test
shall be carried out prior to leaving the site.
,
f) Make sure that cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with manufacturer s instructions.
h) Do not overll cylinders. (No more than 80% volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders have been lled correctly and the process completed, make sure that
the cylinders and the equipment are removed from site promptly and all isolation valves
on the equipment are closed off.
k) Recovered refrigerant shall not be charged into another refrigeration system unless it has
been cleaned and checked.
18. Labelling
Equipment shall be labelled stating that it has been de-commissioned and emptied of
refrigerant. The label shall be dated and signed. Ensure that there are labels on the
equipment stating the equipment contains ammable refrigerant.
Page 43
The recovered refrigerant shall be returned to the refrigerant supplier in the correct
recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants
in recovery units and especially not in cylinders.
If compressors or compressor oils are to be removed, ensure that they have been
evacuated to an acceptable level to make certain that ammable refrigerant does not
remain within the lubricant. The evacuation process shall be carried out prior to retruning
the compressor to the suppliers. Only electric heating to the compressor body shall be
employed to accelerate this process. When oil is drained from a system, it shall be carried
out safely.
19. Recovery
When removing refrigerant from a system, either for service or decommissioning, it is
recommended good practice that all refrigerants are removed safely.
When tranferring refrigerant into cylinders, ensure that only appropriate refrigerant
recovery cylinders are employed. Ensure that the correct numbers of cylinders for holding
the total system charge are available. All cylinders to be used are designated for the
recovered refrigerant and labelled for that refrigerant(i.e special cylinders for the
recovery of refrigerant). Cylinders shall be complete with pressure relief valve and
associated shut-off valves in good working order.
Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions
concerning the equipment that is at hand and shall be suitable for the recovery of
ammable refrigerants. In addition, a set of calibrated weighing scales shall be available
and in good working order.
Hoses shall be complete with leak-free disconnect couplings and in good condition. Before
using the recovery machine, check that it is in satisfactory working order, has been
properly maintained and that any associated electrical components are sealed to prevent
ignition in the event of a refrigerant release. Consult manufacturer if in doubt.
1. Transport of equipment containing ammable refrigerants
Compliance with the transport regulations
2. Marking of equipment using signs
Compliance with local regulations
3. Disposal of equipment using ammable refrigerants
Compliance with national regulations
4. Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer’s instructions.
5. Storage of packed (unsold) equipment
Storage package protection should be constructed such that mechanical damage to the
equipment inside the package will not cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be stored together will be
determined by local regulations.
