WARNING
The following applies to R32 refrigerant systems.
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure
that the risk of ignition is minimized.
For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work
on the system.
Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour
being present while the work is being performed.
All maintenance staff and others 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 by control of flammable material.
The area shall be checked with an appropriate refrigerant detector prior to 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.
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 CO fire extinguisher adjacent to 2
the charging area.
No person carrying out work in relation to a refrigeration system which 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 riskof fire or explosion.
All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of
installation, repairing, removing 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.
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.
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 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 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 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.
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 in a safe manner to avoid possibility of sparking;
-that no live electrical components and wiring are exposed whiule charging, recovering or purging the system;
-that there is continuity of earth bonding.
About The Refrigerant
6
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.
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 specification, damage to seals, incorrect fitting of glands,
etc.
Ensure that seals or sealing materials have not degraded such 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.
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.
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 ageing or continual
vibration from sources such as compressors or fans.
When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures
shall be used. However, it is important that best practice is 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 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 absolutely 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.
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.
Prior to recharging the system it shall be pressure tested with OFN.
DD.12 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 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.
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.
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 overfill cylinders. (No more than 80 % volume liquid charge).
7
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) 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.
k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
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.
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 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 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 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.
Warning: disconnect the appliance from its power source during service and when replacing parts.
These units are partial unit air conditioners, complying with partial unit requirements of this International
Standard, and must only be connected to other units that have been confirmed as complying to corresponding
partial unit requirements of this International Standard.

Normal Protection Of The Air Conditioner
During operation, the following phenomena are normal and do not require maintenance.
Symptoms That Are Not Faults
In heating mode (including heating in automatic mode), when the indoor heat exchanger does
not reach a certain temperature, the indoor fan temporarily shuts off, or runs in Low mode until
the heat exchanger heats up to prevent the blowing of cold air.
When the power switch is on, the air conditioner starts 3-5 minutes after it is turned ON again
in case it was turned off just before.
(Heat
pump type)
Defrosting
When the outdoor temperature is low and the humidity is high, the outdoor unit’s heat
exchanger may become frosted, which may reduce the heating capacity of the air conditioner.
If this occurs, the air conditioner will stop heating, enter automatic defrosting mode, and return
to heating mode after defrosting has been completed.
During the defrosting, the outdoor fan stops running and the indoor fan runs using the anti-cold
air protection function.
The defrosting operation time varies depending on the outdoor temperature and the degree of
frosting. It generally takes 2 to 10 minutes.
During the defrosting process, the outdoor unit may emit steam due to the rapid defrosting, which is
normal.
When the indoor unit detects high humidity, the air conditioner will adjust the louver angle and
the fan speed to prevent condensation and avoid dripping. (If a third-party panel is selected,
this function is not available.)

The Following Symptoms Are Not System Malfunctions
①
When humidity is high during cooling mode, white mist may appear due to the humidity and the
temperature difference between the air inlet and outlet.
②
When the air conditioner is switched to heating mode after defrosting, the indoor unit discharges the
moisture generated from defrosting as steam.
The indoor unit emits white mist
When filter is very dirty, dust may enter the indoor unit and be blown out.
The indoor unit blows dust
The indoor unit absorbs the odors of rooms, furniture or cigarettes, etc., and disperses the odors during
operation. It is advised to have the air conditioner cleaned and maintained regularly by professional
technicians.
The indoor unit emits odor
When the indoor humidity is high, condensation and water may drip out of the unit.
Water drips
The following phenomena are normal during operation of the air conditioner. They can be solved
according to the instructions below or do not need to be solved.
During self-cleaning, there may be a slight clicking sound from the melting thin ice about 10
minutes.
"Self-cleaning" sound of icing
① A continuous low "hissing" sound is heard when the system is in "Auto", "Cool", "Dry", and
"Heat" modes. This is the sound of refrigerant gas flowing through both indoor and outdoor
units.
② A "hissing" sound is heard at the start or immediately after stopping operation or defrost
operation. This is the noise of refrigerant caused by flow change.
③ A "zeen" sound is heard immediately after the power supply is turned on. The electronic
expansion valve inside an indoor unit starts working and makes the noise. it will reduce in
about one minute.
④ A continuous low "shah" sound is heard when the system is in cooling mode, dry mode or
at a stop. When the drain pump (optional accessories) is in operation, this noise is heard.
⑤ A "pishi-pishi" squeaking sound is heard when the system stops after heating operation.
Expansion and contraction of plastic parts caused by temperature change make this noise.
⑥ A low "sah", "choro-choro" sound is heard while the indoor unit is stopped. When another
indoor unit is in operation, this noise is heard. In order to prevent oil and refrigerant from
remaining in the system, a small amount of refrigerant is kept flowing.
Noise of Indoor unit
When the indoor unit reaches the set temperature, the air conditioner controller automatically
stops the compressor operation and switches to the fan only mode. When the room temperature
rises (in cooling mode) or falls (in heating mode) to a certain level, the compressor is restarted
and cooling or heating operation is resumed.
Switching from cooling/heating (not available for cooling only units) mode to fan only mode
13
① In heating mode, the air-conditioning system absorbs heat from the outdoor air and
releases heat to the indoor side. When the outdoor temperature is low, less heat is
released. This is the principle of heat pump.
② When the outdoor temperature is extremely low, the heating capacity of the air conditioner
decreases, and other heating equipment may need to be added.
In winter, the outdoor temperature is low, and heating effects may be decreased
For the same air conditioning system, if outdoor unit operates in changeover mode, the wired
controller of VIP indoor unit allows users to select modes supported by the indoor units, while the
wired controllers of other indoor units displays the icon of " ". In this case,
other indoor units can only operate in the same mode as the VIP indoor unit.
