SAFETY PRECAUTIONS
!
WARNING
• Installation and maintenance should be performed by
qualified persons who are familiar with local code and
regulation, and experienced with this type of appliance.
• All field wiring must be installed in accordance with the
national wiring regulation.
• Ensure that the rated voltage of the unit corresponds to
that of the name plate before commencing wiring work
according to the wiring diagram.
• The unit must be GROUNDED to prevent possible hazard
due to insulation failure.
• All electrical wiring must not touch the refrigerant piping
or any moving parts of the fan motors.
• Confirm that the unit has been switched OFF before
installing or servicing the unit.
• Disconnect from the main power supply before servicing
the air conditioner unit.
• DO NOT pull out the power cord when the power is ON.
This may cause serious electrical shocks which may result
in the fire hazards.
NOTICE
This product is subjected to Waste of Electrical
and Electronic Equipment Regulations (WEEE
Regulations). The waste product shall be
separately collected by specific collection and
treatment centre. Please refer to local authority
for these centres. This is only applicable to
European Union countries.
INSTALLATION OF THE INDOOR UNIT
1. Preliminary Site Survey
• Electrical supply and installation shall conform to the local
authority (e.g. National Electrical Board).
• Voltage supply fluctuation must not exceed ±10% of the
rated voltage. Electricity supply lines must be independent
of welding transformers which can cause high supply
fluctuation.
• Ensure that the installation location is convenient for wiring
and piping.
2. Standard Mounting
Figure A
• Ensure that the overhead supports are strong enough to
hold the weight of the unit.
• Position the hanger rods (wall mounting bracket for floor
standing), and check for its alignment with the unit as
shown in Figure A.
• Also, check that the hangers are secured and the base of
the fan coil unit is leveled in both horizontal directions,
taking into account the gradient for drainage flow as
recommended in Figure B.
!
CAUTION
Please take note of the following important points when
installing.
• Do not install the unit where leakage of flammable gas
may occur.
If gas leaks and accumulates around the unit, it may
cause fire ignition.
• Ensure that the drainage piping is connected properly.
If the drainage piping is not connected properly, it may
cause water leakage which will dampen the furniture.
• Do not overcharge the unit.
This unit is factory pre-charged. Overcharge will cause
over-current or damage to the compressor.
• Ensure that the units panel is closed after service or
installation.
Unsecured panels will cause the unit to operate noisily.
• Sharp edges and coil surfaces are potential locations
which may cause injury hazards. Avoid from being in
contact with these places.
• Before turning off the power supply, set the remote
controller’s ON/OFF switch to the “OFF” position to
prevent the nuisance tripping of the unit.
If this is not
done, the unit’s fans will start turning automatically when
power resumes, posing a hazard to service personnel or the
user.
• Do not operate any heating apparatus too close to the
air conditioner unit.
This may cause the plastic panel to
melt or deform as a result of the excessive heat.
• IMPORTANT : DO NOT INSTALL OR USE THE AIR
CONDITIONER UNIT IN A LAUNDRY ROOM.

Please ensure that the following steps are taken:
• Check the gradient for drainage flow as recommended in
Figure B.
• Provide clearance for easy servicing and optimal air flow
as shown in Figure C.
• The indoor unit must be installed such that there is no
short circuit of the cool discharge air with the warm return
air.
• Do not install the indoor unit where there is direct sunlight
shining on the unit. The location should be suitable for
piping and drainage installation. The unit must be a large
distance away from the door.
