5. Information on Servicing
Service should only be performed by a qualified technician.
1) Inspect the area
Before working on systems containing flammable refrigerants, it is necessary to ensure that the
risk of ignition is minimized. Comply with the following precautions before working on
or repairing the refrigerating system.
2) Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of a flammable
gas or vapor being present while the work is being performed.
3) General work area
All maintenance staff and other people working in the local area shall be instructed on the
nature of work being carried out. Work in confined spaces shall be avoided. The area around the
workspace shall be sectioned off. Ensure that the conditions within the area have been made
safe through control of the flammable material.
4) Checking for the presence of refrigerants
The area shall be checked with an appropriate refrigerant detector prior to and during work to
ensure that the technician is aware of potentially flammable atmospheres. Ensure that the leak
detection equipment being used is suitable for use with flammable refrigerants,
i.e., non-sparking, adequately sealed, or intrinsically safe.
5) Presence of a fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts,
appropriate fire extinguishing equipment shall be on hand. Be sure to have a dry powder or CO
2
fire extinguisher adjacent to the charging area.
6) No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any
pipe work that contains or used to contain flammable refrigerant shall use any sources of ignition
in such a manner that may lead to the risk of fire or an explosion. All possible ignition sources
including cigarette smoking should be kept at a sufficient distance from the site of installation,
repair, removal, and disposal, during which flammable refrigerant can possibly be released to the
surrounding space. Prior to work taking place, the area around the equipment is to be surveyed
to make sure that there are no flammable hazards or ignition risks.
No Smoking signs shall be displayed.
7) Ventilated area
Ensure that the area is an open space or that it is adequately ventilated before breaking into the
system or conducting any hot work. There should be a degree of continuous ventilation while
the work is being carried out. The ventilation should safely disperse any released refrigerant and
preferably expel it externally into the atmosphere.
8) Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the
correct specification. At all times, the manufacturer's maintenance and service guidelines shall
be followed. When in doubt, consult Customer Service for assistance. The following checks shall
be applied to installations using flammable refrigerants:
The charge size is in accordance with the room size within which the parts containing
refrigerants are installed.
The ventilation machinery and outlets should operate adequately and should not obstructed;
ifan indirect refrigerating circuit is being used, the secondary circuit shall be checked for the
presence of refrigerants.
Any marking to the equipment should continue to be visible and legible. Markings and signs that
are illegible shall be corrected.
Refrigeration pipes 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 corroded.
9) Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and Initial
safety checks shall include:
Ensuring that capacitors are discharged: this shall be done in a safe manner to avoid possible
sparking;
Ensuring that no live electrical components and wiring are exposed while charging, recovering,
or purging the system; Ensuring that there is continuity of earth bonding;
7. Repairs to Sealed Components
1) During repairs to sealed components, all electrical supplies shall be disconnected from the unit
being worked on prior to the removal of sealed covers and other parts (if any). If it is necessary
to have an electrical supply connected to the unit 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.
2) Particular attention shall be paid to the following to ensure that when 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 the cables, an excessive number of connections, terminals not made to
the original specification, damage to seals, incorrect fitting of glands, etc.
Ensure that the unit is mounted securely.
Ensure that the seals or sealing materials have not been degraded to a point that they no longer
serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall
be in accordance with the manufacturer's specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection
equipment. Intrinsically safe components do not have to be isolated prior to working on them.
8. Repair to Intrinsically Safe Components
Do not apply any permanent inductive or capacitive loads to the circuit without ensuring that this will
not exceed the permissible voltage and current for the unit in use. Intrinsically safe components are
the only types that can be worked on while live and in the presence of a flammable atmosphere. The
test apparatus shall be at the correct rating. Replace the components only with parts specified by the
manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
9. Cabling
Check that the cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges,
or any other adverse environmental effects. The check shall also consider the effects of aging or continual
vibration from sources such as compressors or fans.
10. Detection of Flammable Refrigerants
Under no circumstances shall potential sources of ignition be used in searching for or detecting refrigerant
leaks. A halide torch (or any other detector using a naked flame) shall not be used.
11. Leak Detection Methods
The following leak detection methods are deemed acceptable for systems containing flammable
refrigerants. Electronic leak detectors shall be used to detect flammable 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 used. 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 confirmed. Leak detection fluids 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
pipework. If a leak is suspected, all naked flames shall be removed / extinguished. If a refrigerant leak is
found (which requires brazing), all refrigerants shall be recovered from the system, or isolated (by means
of shut off valves) in a part of the system that is situated remotely from the leak. Oxygen free nitrogen
(OFN) shall then be purged from the system both before and during the brazing process.

5. Information on Servicing
Service should only be performed by a qualified technician.
1) Inspect the area
Before working on systems containing flammable refrigerants, it is necessary to ensure that the
risk of ignition is minimized. Comply with the following precautions before working on
or repairing the refrigerating system.
2) Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of a flammable
gas or vapor being present while the work is being performed.
3) General work area
All maintenance staff and other people working in the local area shall be instructed on the
nature of work being carried out. Work in confined spaces shall be avoided. The area around the
workspace shall be sectioned off. Ensure that the conditions within the area have been made
safe through control of the flammable material.
4) Checking for the presence of refrigerants
The area shall be checked with an appropriate refrigerant detector prior to and during work to
ensure that the technician is aware of potentially flammable atmospheres. Ensure that the leak
detection equipment being used is suitable for use with flammable refrigerants,
i.e., non-sparking, adequately sealed, or intrinsically safe.
5) Presence of a fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts,
appropriate fire extinguishing equipment shall be on hand. Be sure to have a dry powder or CO
2
fire extinguisher adjacent to the charging area.
6) No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any
pipe work that contains or used to contain flammable refrigerant shall use any sources of ignition
in such a manner that may lead to the risk of fire or an explosion. All possible ignition sources
including cigarette smoking should be kept at a sufficient distance from the site of installation,
repair, removal, and disposal, during which flammable refrigerant can possibly be released to the
surrounding space. Prior to work taking place, the area around the equipment is to be surveyed
to make sure that there are no flammable hazards or ignition risks.
No Smoking signs shall be displayed.
7) Ventilated area
Ensure that the area is an open space or that it is adequately ventilated before breaking into the
system or conducting any hot work. There should be a degree of continuous ventilation while
the work is being carried out. The ventilation should safely disperse any released refrigerant and
preferably expel it externally into the atmosphere.
8) Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the
correct specification. At all times, the manufacturer's maintenance and service guidelines shall
be followed. When in doubt, consult Customer Service for assistance. The following checks shall
be applied to installations using flammable refrigerants:
The charge size is in accordance with the room size within which the parts containing
refrigerants are installed.
The ventilation machinery and outlets should operate adequately and should not obstructed;
ifan indirect refrigerating circuit is being used, the secondary circuit shall be checked for the
presence of refrigerants.
Any marking to the equipment should continue to be visible and legible. Markings and signs that
are illegible shall be corrected.
Refrigeration pipes 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 corroded.
9) Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and Initial
safety checks shall include:
Ensuring that capacitors are discharged: this shall be done in a safe manner to avoid possible
sparking;
Ensuring that no live electrical components and wiring are exposed while charging, recovering,
or purging the system; Ensuring that there is continuity of earth bonding;
7. Repairs to Sealed Components
1) During repairs to sealed components, all electrical supplies shall be disconnected from the unit
being worked on prior to the removal of sealed covers and other parts (if any). If it is necessary
to have an electrical supply connected to the unit 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.
2) Particular attention shall be paid to the following to ensure that when 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 the cables, an excessive number of connections, terminals not made to
the original specification, damage to seals, incorrect fitting of glands, etc.
Ensure that the unit is mounted securely.
Ensure that the seals or sealing materials have not been degraded to a point that they no longer
serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall
be in accordance with the manufacturer's specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection
equipment. Intrinsically safe components do not have to be isolated prior to working on them.
8. Repair to Intrinsically Safe Components
Do not apply any permanent inductive or capacitive loads to the circuit without ensuring that this will
not exceed the permissible voltage and current for the unit in use. Intrinsically safe components are
the only types that can be worked on while live and in the presence of a flammable atmosphere. The
test apparatus shall be at the correct rating. Replace the components only with parts specified by the
manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
9. Cabling
Check that the cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges,
or any other adverse environmental effects. The check shall also consider the effects of aging or continual
vibration from sources such as compressors or fans.
10. Detection of Flammable Refrigerants
Under no circumstances shall potential sources of ignition be used in searching for or detecting refrigerant
leaks. A halide torch (or any other detector using a naked flame) shall not be used.
11. Leak Detection Methods
The following leak detection methods are deemed acceptable for systems containing flammable
refrigerants. Electronic leak detectors shall be used to detect flammable 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 used. 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 confirmed. Leak detection fluids 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
pipework. If a leak is suspected, all naked flames shall be removed / extinguished. If a refrigerant leak is
found (which requires brazing), all refrigerants shall be recovered from the system, or isolated (by means
of shut off valves) in a part of the system that is situated remotely from the leak. Oxygen free nitrogen
(OFN) shall then be purged from the system both before and during the brazing process.
12 13
12. Removal and Evacuation
When breaking into the refrigerant circuit to make repairs or for any other purpose, conventional
procedures shall be used. Considering flammability, follow best practices. Opening of the refrigeration
systems shall not be done by brazing. Adherence to the following procedures is a must:
a) Removing the refrigerant;
b) Purging the circuit with inert gas;
c) Evacuation;
d) Purging again with inert gas;
e) Opening the circuit by cutting or brazing;
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be flushed
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.
Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the
working pressure is achieved, then venting to the atmosphere, and finally pulling down to a vacuum. This
process shall be repeated until no refrigerant is inside the system. When the final 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 pipework are to take place.
Ensure that the outlet for the vacuum pump is not near any ignition sources and that ventilation
is available.
13. 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 the 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 before charging the system with the refrigerant. Label the
system when the charging is complete (in case it has not been labeled yet).
Extreme care shall be taken to avoid overfilling the refrigeration system.
Prior to recharging the system, the pressure test with OFN must first be conducted. The system leak test
shall be performed upon completion of charging, but should be done prior to commissioning.
A follow up leak test shall be carried out before leaving the site.
14. Decommissioning
Before carrying out this procedure, it is essential that the technician is completely familiar with the
equipment and all necessary details. It is good practice that all refrigerants be recovered safely.
Prior to carrying out this task, an oil and refrigerant sample shall be taken in case analysis is required
before reusing the reclaimed refrigerant. It is essential that electrical power is available before
this task commences.
a) Become familiar with the equipment and its operation.
b) Isolate the system electrically.
c) Before attempting the procedure, ensure that:
Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
Allpersonal protective equipment is available and being used correctly;
The recovery process is always supervised by a competent person and recovery equipment
and cylinders conform to the required standards.
d) Pump down the refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerants can be removed from
various parts of the system.
f) Make sure that the cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with the manufacturer's instructions.
h) Do not overfill the 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 filled correctly and the process is completed, make sure that the
cylinders and the equipment are removed from the 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.
15. Labeling
The unit shall be labeled stating that it has been decommissioned and emptied of the refrigerant.
The label shall be dated and signed. Ensure that there are labels on the unit stating that it contains
flammable refrigerants.
16. Recovery
When removing the refrigerant from a system, either for servicing or decommissioning, it is recommended
that all refrigerants are removed safely.
When transferring the refrigerant into the cylinders, ensure that only appropriate refrigerant recovery
cylinders are used. Ensure that the correct number of cylinders for holding the total system charge
is available. All cylinders to be used are designated for the recovered refrigerant and labeled for that
refrigerant (i.e., special cylinders refrigerant recovery). Cylinders shall be complete with pressure relief
valves and associated shut-off valves in good working order. Empty recovery cylinders should be evacuated
and, if possible, cooled before the 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 flammable 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 if a refrigerant is released. Consult Customer Service when in
doubt.
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 the compressors or the compressor oils are to be removed, ensure that they have been
evacuated to an acceptable level so that the flammable refrigerant does not remain within the lubricant.
The evacuation process shall be carried out prior to returning the compressor to the suppliers.
Only electric heating to the compressor body shall be employed to accelerate this process.
When oil is drained from the system, it shall be carried out safely.

HOW TO USE THE BASIC FUNCTIONS
26 27
Clean your Air Conditioner to keep it looking new and to minimize dust buildup.
Always disconnect the appliance before doing any cleaning or maintenance.
The air filter should be checked at least once every
month to see if it needs cleaning. Trapped particles
and dust can build up in the filter and may decrease
airflow and cause the cooling coils to accumulate frost.
Clean the Air Filter:
1. Push the vent handle to the vent closed position
(where applicable). Open the front panel. Hold the
middle of the filter and pull it out
2. Wash the filter using liquid dish soap and warm
water. Rinse the filter thoroughly. Gently shake the
filter to remove excess water
3. Let the filter dry completely before placing it back
in the Air Conditioner
4. If you do not wish to wash the filter, you may vacuum the filter
to remove the dust and other particles
NOTE: Do not use hot water over 104°F (40°C) to clean the air filter.
Do not attempt to operate the unit without the air filter.
To minimize wear and tear on the Air Conditioner, always wait at least 3 minutes before changing modes.
This will help prevent the compressor from overheating and the circuit breaker from tripping.
Clean the AC Unit Housing
• Unplug the Air Conditioner to prevent shock or fire hazard. The housing and the front panel of the
unit may be dusted with an oil-free cloth or wiped with a cloth dampened in a solution of warm
water and mild liquid soap. Wipe the housing dry.
• Never use harsh cleaners, wax, or polish on the housing.
• Be sure to wring excess water from the cloth before wiping around the controls.
Excess water in or around the controls may cause damage to the Air Conditioner.
Store the Air Conditioner if it will not be used for an extended period of time. Remove the Air
Conditioner carefully from the window according to the installation instructions, then cover it with
plastic, or place it in the original box.
Indents
FOLLOW ME SETTING
This feature can be activated through the Remote Control ONLY. When the FOLLOW ME feature is
activated, the remote will then act as the thermostat instead of the unit, helping the unit to more
accurately cool to your desired temperature by sensing the ambient temperature of the area where the
remote is located.
• To activate the FOLLOW ME feature, point the Remote Control towards the unit and press the
FOLLOW ME button. The Remote Control will display the actual temperature at its current location.
The Remote Control will send this signal to the Air Conditioner every 3 minutes until the FOLLOW
ME button is pressed again. If the unit does not receive the FOLLOW ME signal during any 7-minute
interval, the unit will beep to indicate that the FOLLOW ME mode has ended.
• To deactivate this feature, just press the FOLLOW ME button again.
NOTE: When an error code appears, unplug the unit and restart it. If the error code reappears,
contact Customer Service.
The Fresh Air Vent allows the AC unit to regulate the flow of air, and to:
• Recirculate the inside air when the vent is closed. (See > Fig. A)
• Draw fresh air into the room when the vent is open. (See > Fig. B)
• Exchange air from the room and draw fresh air into the room when the vent
and the exhaust are open. (See > Fig. C)
Adjusting the Louvers:
Move the left and right louver levers to adjust air flow direction. You can also press the top or bottom
of the louvers to tilt them. This adjusts the air flow up or down.

Clean your Air Conditioner to keep it looking new and to minimize dust buildup.
Always disconnect the appliance before doing any cleaning or maintenance.
The air filter should be checked at least once every
month to see if it needs cleaning. Trapped particles
and dust can build up in the filter and may decrease
airflow and cause the cooling coils to accumulate frost.
Clean the Air Filter:
1. Push the vent handle to the vent closed position
(where applicable). Open the front panel. Hold the
middle of the filter and pull it out
2. Wash the filter using liquid dish soap and warm
water. Rinse the filter thoroughly. Gently shake the
filter to remove excess water
3. Let the filter dry completely before placing it back
in the Air Conditioner
4. If you do not wish to wash the filter, you may vacuum the filter
to remove the dust and other particles
NOTE: Do not use hot water over 104°F (40°C) to clean the air filter.
Do not attempt to operate the unit without the air filter.
To minimize wear and tear on the Air Conditioner, always wait at least 3 minutes before changing modes.
This will help prevent the compressor from overheating and the circuit breaker from tripping.
Clean the AC Unit Housing
• Unplug the Air Conditioner to prevent shock or fire hazard. The housing and the front panel of the
unit may be dusted with an oil-free cloth or wiped with a cloth dampened in a solution of warm
water and mild liquid soap. Wipe the housing dry.
• Never use harsh cleaners, wax, or polish on the housing.
• Be sure to wring excess water from the cloth before wiping around the controls.
Excess water in or around the controls may cause damage to the Air Conditioner.
Store the Air Conditioner if it will not be used for an extended period of time. Remove the Air
Conditioner carefully from the window according to the installation instructions, then cover it with
plastic, or place it in the original box.
Indents
FOLLOW ME SETTING
This feature can be activated through the Remote Control ONLY. When the FOLLOW ME feature is
activated, the remote will then act as the thermostat instead of the unit, helping the unit to more
accurately cool to your desired temperature by sensing the ambient temperature of the area where the
remote is located.
• To activate the FOLLOW ME feature, point the Remote Control towards the unit and press the
FOLLOW ME button. The Remote Control will display the actual temperature at its current location.
The Remote Control will send this signal to the Air Conditioner every 3 minutes until the FOLLOW
ME button is pressed again. If the unit does not receive the FOLLOW ME signal during any 7-minute
interval, the unit will beep to indicate that the FOLLOW ME mode has ended.
• To deactivate this feature, just press the FOLLOW ME button again.
NOTE: When an error code appears, unplug the unit and restart it. If the error code reappears,
contact Customer Service.
The Fresh Air Vent allows the AC unit to regulate the flow of air, and to:
• Recirculate the inside air when the vent is closed. (See > Fig. A)
• Draw fresh air into the room when the vent is open. (See > Fig. B)
• Exchange air from the room and draw fresh air into the room when the vent
and the exhaust are open. (See > Fig. C)
Adjusting the Louvers:
Move the left and right louver levers to adjust air flow direction. You can also press the top or bottom
of the louvers to tilt them. This adjusts the air flow up or down.
