 WARNING

!

 CAUTION

 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 fire hazards.
 Keep the indoor and outdoor units, power cable and transmission 
wiring, at least 1m from TVs and radios, to prevent distorted pictures 
and static. {Depending on the type and source of the electrical 
waves, static may be heard even when more than 1m away}.

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 unit’s 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 install the units at or near doorway.
 Do not operate any heating apparatus too close to the air conditioner 
unit or use in room where mineral oil, oil vapour or oil steam exist, 
this may cause plastic part to melt or deform as a result of excessive 
heat or chemical reaction.
 When the unit is used in kitchen, keep flour away from going into 
suction of the unit.
 This unit is not suitable for factory used where cutting oil mist or 
iron powder exist or voltage fluctuates greatly.
 Do not install the units at area like hot spring or oil refinery plant 
where sulphide gas exists.
 Ensure the color of wires of the outdoor unit and the terminal 
markings are same to the indoors respectively.

 IMPORTANT : DO NOT INSTALL OR USE THE AIR 
CONDITIONER UNIT IN A LAUNDRY ROOM.
 

Don’t use joined and twisted wires for incoming power supply.
 The equipment is not intended for use in a potentially explosive 
atmosphere.
