4

If the supply cord is damaged, it must be
replaced by the manufacturer, service agent
or similarly qualifi ed persons in order to avoid
a hazard.

It is strongly recommended to be installed
with Earth Leakage Circuit Breaker (ELCB)
or Residual Current Device (RCD) to prevent
electric shock or fi re.

T o prevent overheating, fi re or electric shock:

• Insert the power plug properly.

• Dust on the power plug should be periodically
wiped with a dry cloth.

Stop using the product if any abnormality/
failure occurs and disconnect the power plug or
turn off the power switch and breaker.
(Risk of smoke/fi re/electric shock)
Examples of abnormality/failure

• The ELCB trips frequently.

• Burning smell is observed.

• Abnormal noise or vibration of the unit is
observed.

• Water leaks from the indoor unit.

• Power cord or plug becomes abnormally hot.

• Fan speed cannot be controlled.

• The unit stops running immediately even if it
is switched on for operation.

• The fan does not stop even if the operation
is stopped.

Contact your local dealer immediately for
maintenance/repair.

This equipment must be earthed to prevent
electrical shock or fi re.

Prevent electric shock by switching off the
power supply and unplug:

- Before cleaning or servicing,

- When extended non-use, or

- During abnormally strong lightning activity.

CAUTION

Indoor unit and outdoor unit

Do not wash the indoor unit with water,
benzine, thinner or scouring powder to avoid
damage or corrosion at the unit.

Do not use for preservation of precise
equipment, food, animals, plants, artwork
or other objects. This may cause quality
deterioration, etc.

Do not use any combustible equipment in front
of the airfl ow outlet to avoid fi re propagation.

Do not expose plants or pet directly to airfl ow to
avoid injury, etc.

Do not touch the sharp aluminium fi n,
sharp parts may cause injury.

Do not switch ON the indoor unit when waxing
the fl oor. After waxing, aerate the room properly
before operating the unit.

Do not install the unit in oily and smoky areas
to prevent damage to the unit.

Do not dismantle the unit for cleaning purpose
to avoid injury.

Do not step onto an unstable bench when
cleaning the unit to avoid injury.

Do not place a vase or water container on the
unit. Water may enter the unit and degrade the
insulation. This may cause an electric shock.
Do not open window or door for long time during
operation, it may lead to ineffi cient power usage
and uncomfortable temperature changes.

Prevent water leakage by ensuring drainage pipe is:

- Connected properly ,

- Kept clear of gutters and containers, or

- Not immersed in water

After a long period of use or use with any
combustible equipment, aerate the room regularly.

After a long period of use, make sure the
installation rack does not deteriorate to prevent
the unit from falling down.

Remote control

Do not use rechargeable (Ni-Cd) batteries. It
may damage the remote control.

To prevent malfunction or damage of the
remote control:

• Remove the batteries if the unit is not going to
be used for a long period of time.

Safety precautions

WARNING

This appliance is fi lled with R32
(mild fl ammable refrigerant).

If the refrigerant is leaked and exposed to
an external ignition source, there is a risk
of fi re.

Indoor unit and outdoor unit

The appliance shall be installed, and/or
operated in a room with fl oor area larger
than Amin (m²) and keep away from ignition
sources, such as heat/sparks/open fl ame or
hazardous areas such as gas appliances, gas
cooking, reticulated gas supply systems or
electric cooking appliances, etc.(Refer to Table
A of Installation instructions table for Amin (m²))

Be aware that refrigerant may not contain an
odour, highly recommended to ensure suitable
fl ammable refrigerant gas detectors are
present, operating and able to warn of a leak.

Keep any required ventilation openings clear of
obstruction.

Do not pierce or burn as the appliance is
pressurized. Do not expose the appliance to
heat, fl ame, sparks, or other sources of ignition.
Else it may explode and cause injury or death.

Precaution for using R32 refrigerant

The basic installation work procedures are the same as
conventional refrigerant (R410A, R22) models.

Since the working pressure is higher than that
of refrigerant R22 models, some of the piping
and installation and service tools are special.
Especially, when replacing a refrigerant R22
model with a new refrigerant R32 model,
always replace the conventional piping and

fl are nuts with the R32 and R410A piping and
fl are nuts on the outdoor unit side.

For R32 and R410A, the same fl are nut on the
outdoor unit side and pipe can be used.

The mixing of different refrigerants within
a system is prohibited. Models that use
refrigerant R32 and R410A have a different
charging port thread diameter to prevent
erroneous charging with refrigerant R22 and
for safety.
Therefore, check beforehand. [The charging port
thread diameter for R32 and R410A is 1/2 inch.]

Must always ensure that foreign matter (oil,
water, etc.) does not enter the piping. Also,
when storing the piping, securely seal the
opening by pinching, taping, etc. (Handling of
R32 is similar to R410A.)

• Operation, maintenance, repairing and
refrigerant recovery should be carried
out by trained and certifi ed personnel in
the use of fl ammable refrigerants and as
recommended by the manufacturer. Any
personnel conducting an operation, servicing
or maintenance on a system or associated
parts of the equipment should be trained and
certifi ed.

• Any part of refrigerating circuit (evaporators,
air coolers, AHU, condensers or liquid
receivers) or piping should not be located in
the proximity of heat sources, open fl ames,
operating gas appliance or an operating
electric heater.

• The user/owner or their authorised
representative shall regularly check the
alarms, mechanical ventilation and detectors,
at least once a year, where as required by
national regulations, to ensure their correct
functioning.

• A logbook shall be maintained. The results
of these checks shall be recorded in the
logbook.

• In case of ventilations in occupied spaces
shall be checked to confi rm no obstruction.

• Before a new refrigerating system is put
into service, the person responsible for
placing the system in operation should
ensure that trained and certifi ed operating
personnel are instructed on the basis of the
instruction manual about the construction,
supervision, operation and maintenance of
the refrigerating system, as well as the safety
measures to be observed, and the properties
and handling of the refrigerant used.

• The general requirement of trained and
certifi ed personnel are indicated as below:

a) Knowledge of legislation, regulations

and standards relating to fl ammable
refrigerants; and,

b) Detailed knowledge of and skills in

handling fl ammable refrigerants, personal
protective equipment, refrigerant leakage
prevention, handling of cylinders, charging,
leak detection, recovery and disposal; and,

c) Able to understand and to apply in practice

the requirements in the national legislation,
regulations and Standards; and,

d) Continuously undergo regular and further

training to maintain this expertise.

e) Air-conditioner piping in the occupied

space shall be installed in such a way
to protect against accidental damage in
operation and service.
