CONTENTS
Before installing the air conditioner unit, please read the following safety precautions carefully.
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 hazards due to insulation failure.
• All electrical wiring must not touch the refrigerant piping, compressor or any moving parts of the fan motors.
• Confirm that the unit has been switched OFF before installing or servicing the unit.

!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.

INSTALLATION OF THE OUTDOOR UNIT
The outdoor unit must be installed in such a way, so as to
prevent short circuit of the hot discharged air or obstruction
to the smooth air flow. Please follow the installation clear-
ance shown in the figure. Select the coolest possible place
where intake air temperature is not greater than the outside
air temperature (maximum 45°C).
Installation clearance
Note: If there is any obstacle higher than 2m, or if there is
any obstruction at the upper part of the unit, please allow
more space than the figure indicated in the above table.
Condensed Water Disposal of Outdoor Unit (Heat
Pump Unit Only)
•There are 2 holes on the base of Outdoor Unit for
condensed water to flow out. Insert the drain elbow to
one of the holes.
•To install the drain elbow, first insert one portion of the
hook to the base (portion A), then pull the drain elbow
in the direction shown by the arrow while inserting the
other portion to the base. After installation, check to
ensure that the drain elbow clings to base firmly.
•If the unit is installed in a snowy and chilly area, con-
densed water may freeze in the base. In such case, please
remove plug at the bottom of unit to smooth the drain-
age.

INSTALLATION OF THE INDOOR UNIT
Mounting Installation Plate
Ensure that the wall is strong enough to withstand the weight
of the unit. Otherwise, it is necessary to reinforce the wall
with plates, beams or pillars.
Use the level gauge for horizontal mounting, and fix it with
4 suitable screws.
In case the rear piping draws out, drill a hole 65mm in
diameter with a cone drill, slightly lower on the outside wall
(see figure).
Mount The Unit Onto The Installation Plate
Hook the indoor unit onto the upper portion of the
installation plate (Engage the two hooks at the rear top of
the indoor unit with the upper edge of the installation plate).
Ensure that the hooks are properly seated on the
installation plate by moving it to the left and right.
Water Drainage Piping
The indoor drain pipe must be in a downward gradient for
smooth drainage. Avoid situations that are likely to cause
water to leak.

The indoor unit must be installed in such a way so as to
prevent short circuit of the cool discharged air with the hot
return air. Please follow the installation clearance shown in
the figure. Do not place the indoor unit where there could be
direct sunlight shining on it. Also, this location must be
suitable for piping and drainage, and be away from doors or
windows.

Direction
Higher Than
Eye Level
The refrigerant piping can be routed to the unit in a
number of ways (left or right from the back of the unit), by
using the cut-out holes on the casing of the unit (see figure).
Bend the pipes carefully to the required position in order to
aligned it with the holes. For the right hand and rear side
out, hold the bottom of the piping and then position it to the
required direction (see figure). The condensation drain hose
can be taped to the pipes.

Piping Length & Elevation
If the pipe is too long, both the capacity and reliability of
the unit will drop. As the number of bends increases,
resistance to the flow of refrigerant system increases, thus
lowering cooling capacity.As a result, the compressor may
become defective. Always choose the shortest path and
follow the recommendations as tabulated below:

Cutting Copper Tube
Piping Works
• Do not use contaminated or damaged copper tubing. Do
not remove plastic, rubber plugs and brass nuts from the
valves, fittings, tubings and coils until you are ready to
connect suction or liquid line into valves or fittings.
• If any brazing work is required, ensure that the nitrogen
gas is passed through coil and joints while the brazing
work is being done. This will eliminate soot formation on
the inside walls of the copper tubings.
• Cut the connection pipe with a pipe cutter.
• Remove burrs from cut edges of the pipes with remover.
Hold the end of the pipe downwards to prevent metal chips
from entering the pipe.
• Insert the flare nuts, mounted on the connection parts of
both the indoor unit and outdoor unit onto the copper pipes.
• Flare the pipe with extra length above the flaring tool as
shown in the table.
• The flared edge must be even and not cracked or scratched.
