! WARNING
• Installation and maintenance should be performed
by qualifi ed persons who are familiar with local code
and regulation, and experienced with this type of
appliance.
• All fi eld 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.
• Confi rm 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 fi re hazards.
• Keep the air-conditioner 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}.
! CAUTION
Please take note of the following important points
when installing.
• Do not install the unit where leakage of fl ammable
gas may occur.
If gas leaks and accumulates around the unit, it
may cause fi re ignition.
• Ensure that 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 unitʼs 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
controllerʼs ON/OFF switch to the “OFF” position
to prevent the nuisance tripping of the unit. If
this is not done, the unitʼs 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.
• Donʼt use joined and twisted wires for incoming
power supply.

INSTALLATION OF THE UNIT
(a) Location For Installation
Install the unit in such way that air distributed by the unit cannot be drawn in again (as in the case of short circuit of
discharge air). Allow suffi cient space for maintenance around the unit.
When two or more units are installed in a location, they must be positioned such that one unit will not be taking the
discharge air from another unit.
Ensure that there is no obstruction of air fl ow into or out of the unit. Remove obstacles which block air intake or air
discharge.
The location must be well ventilated, so that the unit can draw and distribute plenty of air.
The unit is recommended to install in:-
A place capable of bearing the weight of the unit and isolating noise and vibration.
A place where has adequate drainage.
A place where the unit will not be buried in snow.
A place where air outlet port is not exposed to strong wind.
A place where the air discharge and operating sound level will not annoy the neighbours.
The location where it is not accessible by general public.
(b) Duct Construction
• This unit are equipped with supply and return air openings. Duct connection to the unit should be made with duct
fl anges and secured directly to the air openings with fl exible duct connectors to avoid normal noise transmission.
• To prevent air leakage, all duct seams should be sealed.
• Ducts in the spaces that not air-conditioned, must be insulated.
• Ducts exposed to the outside must be weather proofed.
• Ducts that entering building through the roof, the entering should be sealed with weather stripping to prevent rain, sand,
dust etc, from entering the building.
• Correct size of fi lter must be installed at the return air duct.
