Information on servicing
-
Checks to the area
Before beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. -
Work procedure
Work shall be undertaken under a controlled procedure to minimise the risk of a flammable gas or vapour being present while the work is being performed. -
General work area
All maintenance staff and others working in the local area shall be instructed on the nature of the 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 by control of flammable material. -
Checking for the presence of refrigerant
The area shall be checked with an appropriate refrigerant detector before and during work, to ensure 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. -
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 available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area. -
No ignition sources
No person carrying out work about a refrigeration system that involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repair, removal and disposal, during which flammable refrigerant can be released to the surrounding space. Before work takes 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. -
Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. -
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. If in doubt consult the manufacturer’s technical department for assistance. The following checks shall be applied to installations using flammable refrigerants: -
The charge size is under 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 circuit shall be checked for the presence of refrigerant; Marking to the equipment continues 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 that may corrode refrigerant-containing components unless the components are constructed of materials that are inherently resistant to being corroded or are suitably protected against being so corroded.
-
Checks to electrical devices 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, an 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 safely to avoid the possibility of sparking;
-
That no live electrical components and wiring are exposed while charging, recovering or purging the system;
-
That there is continuity of earth bonding.
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. Intrinsically safe components are the only
types that can be worked on while live in the presence of a flammable
atmosphere. The test apparatus shall be at the correct rating. Replace
components only with parts specified by the manufacturer. Other parts may
result in the ignition of refrigerant in the atmosphere from a leak.
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.
Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the
search for or detection of refrigerant leaks. A halide torch (or any other
detector using a naked flame) shall not be used.
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 pipe-work. If a leak is suspected, all
naked flames shall be removed/extinguished. If leakage of refrigerant is found
which requires brazing, all of the refrigerants shall be recovered from the
system, or isolated (through 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.
Removal and evacuation
When breaking into the refrigerant circuit to make repairs or for any other
purpose conventional procedures shall be used. However, best practice must be
followed since flammability 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. 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 within 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 vital if brazing operations on
the pipe work are to take place. Ensure that the outlet for the vacuum pump is
not close to any ignition sources and there is ventilation available.
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 minimise the amount of refrigerant contained in them. Cylinders
shall be kept upright. Ensure that the refrigeration system is earthed before
charging the system with refrigerant. Label the system when charging is
complete (if not already). Extreme care shall be taken not to overfill the
refrigeration system. Before recharging the system it shall be pressure tested
with OFN. The system shall be leak tested on completion of charging but before
commissioning. A follow-up leak test shall be carried out before leaving the
site.
Decommissioning
Before carrying out this procedure, the technician must be completely familiar
with the equipment and all its details. It is recommended good practice that
all refrigerants are recovered safely. Before the task is carried out, an oil
and refrigerant sample shall be taken in case analysis is required before re-
use of reclaimed refrigerant. Electrical power must be available before the
task is commenced.
- Become familiar with the equipment and its operation.
- Isolate system electrically.
- Before attempting the procedure ensure that: Mechanical handling equipment is available, if required, for handling refrigerant cylinders; All personal protective 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.
- Pump down the refrigerant system, if possible.
- If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
- Make sure that the cylinder is situated on the scales before recovery takes place.
- Start the recovery machine and operate it under the manufacturer’s instructions.
- Do not overfill cylinders. (No more than 80 % volume liquid charge).
- Do not exceed the maximum working pressure of the cylinder, even temporarily.
- When the cylinders have been filled 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.
- Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
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 flammable
refrigerant.
Recovery
When removing refrigerant from a system, either for servicing or
decommissioning, it is recommended good practice that all refrigerants are
removed safely. When transferring refrigerant into cylinders, ensure that only
appropriate refrigerant recovery cylinders are employed. 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
labelled for that refrigerant (i.e. special cylinders for the recovery of
refrigerant).
IMPORTANT SAFETY INSTRUCTIONS
Cylinders shall be complete with pressure relief valves 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 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 in the event of a refrigerant release. Consult the manufacturer if 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 compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that 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 a system, it shall be carried out safely.
Gentle Reminder
Check the appliance regularly and refer to TROUBLESHOOTING or contact our
customer support if it shows any of the following signs:
- Power cord or plug is damaged.
- Loud noise, unusual smell or excessive heat.

Please note that
- The installation site should be in a well-ventilated condition.
- The sites for installing and maintaining an air conditioner using Refrigerant R32 should be free from open fire or welding, smoking, drying oven or any other heat source higher than 548 which easily produces open fire.
- When installing an air conditioner, it is necessary to take appropriate anti-static measures such as wear anti-static clothing and/or gloves.
- It is necessary to choose the site convenient for installation or maintenance wherein the air inlets and outlets of the indoor and outdoor units should be not surrounded by obstacles or close to any heat source or combustible and/or explosive environment.
- If the indoor unit suffers refrigerant leak during the installation, all the personnel should go out till the refrigerant leaks completely for 15 minutes. If the product is damaged, it is a must to carry such damaged product back to the maintenance station and it is prohibited to weld the refrigerant pipe or conduct other operations on the user’s site.
- It is necessary to choose the place where the inlet and outlet air of the indoor unit is even.
- It is necessary to avoid the places where there are other electrical products, power switch plugs and sockets, kitchen cabinet, bed, sofa and other valuables right under the lines on two sides of the indoor unit, and also prevent mechanical damage from occurring.

CLEANING AND MAINTENANCE
Care and Cleaning
Clean your air conditioner occasionally to keep it looking new. Be sure to
unplug the unit before cleaning to prevent shock or fire hazards.
Air Filter Cleaning
The air filter should be checked at least once every month to see if it needs
cleaning. Never use hot water over 104 F (40ooC) to clean the air filter.
Never attempt to operate the unit without the air filter.
Trapped particles and dust can build up in the filter and may decrease airflow
as well as cause the cooling coils to accumulate frost. To clean the air
filter:
- Pull the grille out from the indents on both sides at the front and remove the filter inside.
- Wash the filter using liquid dish soap and warm water. Rinse the filter thoroughly. Gently shake the filter to remove excess water.
- Let the filter dry completely before placing it into the air conditioner.
- If you do not wish to wash the filter, you may vacuum the filter to remove the dust and other particles.
Cabinet Cleaning
To clean the air conditioner cabinet:
- Unplug the air conditioner to prevent shock or a fire hazard. The cabinet and front panel of the air conditioner may be dusted with an oil free cloth or washed with a cloth dampened in a solution of warm water and mild liquid soap. Rinse thoroughly with a damp cloth and wipe dry.
- Never use harsh cleaners, wax or polish on the cabinet front.
- 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.
Winter Storage
To store the air conditioner when it is not in use for an extended period of
time, remove it carefully from the window according to the installation
instructions and cover it with plastic or place it in the original box.
