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 hazard due to insulation failure.
• All electrical wiring must not touch the refrigerant piping, compressor and any moving parts of the fan motors.
• Confirm that the unit has been switched OFF before installing or servicing the unit.
IMPORTANT
DO NOT INSTALL OR USE THEAIR CONDITIONER UNIT INA LAUNDRY ROOM.
CONTENTS
!Caution
Please take note on the following important points when installing.
• Do not install the unit where leakage of flammable gas may occur.
If gas leaks and accumulates at the surrounding of 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 panel is covered back after service or installation.
Unsecured panel will cause 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.
!Caution
INSTALLATION OF THE INDOOR UNIT
The indoor unit must be installed such that there is no short
circuit of the cool discharge. Respect the installation clear-
ance (see drawing C). Do not put the indoor unit where there
is direct sunlight on unit. The location is suitable for piping
and drainage and it must be have a large distance between a
door and unit.
CEILING CONCEALED MOUNTING
– Use the hanger supplied with the unit.
– Make sure that the wall is sufficiently strong to withstand
the weight.

The location must be well-ventilated, so that the unit can
draw in and distribute plenty of air thus lowering the
temperature.
A place capable of bearing the weight of the outdoor unit as
well as isolating noise and vibration.
A place protected from the direct sunlight. Use an
awning for protection if necessary. Note:- If the obstacle is higher than 2m or if there is any
obstruction at the upper part of the unit allow more
space than indicated in the table above.
The installation location must not be susceptible to highly
concentrated dust, oil, salt or sulfide gas.

INSTALLATION OF THE OUTDOOR UNIT
The outdoor unit must be installed such that there is no short
circuit of the air discharge air or obstruction to smooth air
flow. Respect the installation clearance show on the table.
Select the coolest possible place where intake air should
notbehigherthan theoutside temperature(maximum 45°C).
Ensure that there are no obstruction of air flow into or out

REFRIGERANT PIPING
MAXIMUM PIPE LENGTH AND MAXIMUM
NUMBER OF BENDS
When the pipe length becomes too long, both the capacity
and reliability drop. As the number of bends increases,
system piping resistance to the refrigerant flow increases,
thus lowering the cooling capacity. As a result, compressor
reliability will be affected. Always choose the
shortest path and follow the recommendation as tabulated
below:
PIPING WORKS AND FLARING TECHNIQUE
Do not use contaminated or damaged copper tubing. If any
piping, evaporator or condenser had been exposed or had
been opened for 15 seconds or more, vacuum the system.
Generally, do not remove plastic, rubber plugs and brass
nuts from the valves, fittings, tubings and coils until it is
ready for connection.
If any brazing work is required, ensure that the nitrogen gas
is passed through piping and joints while the brazing work
is being done. This will eliminate soot formation on the
inside walls of the copper tubings.
Cut the pipe stage by stage, advancing the blade of pipe
cutter slowly. Extra force and deep cut will cause more
distortion of pipe and therefore extra burr.
Remove burrs from cut edges of pipes with a remover as
shown in Fig. R. This will avoid unevenness on the flare
faceswhich willcause gasleak. Hold thepipe ontop position
and burr remover at lower position to prevent metal chips
from entering the pipe.
Insert the flare nuts mounted on the connection parts of both
indoor and outdoor unit, into the copper pipes.
The exact length of pipe protruding from the face of the
flare die is determined by the flaring tool.
Fix the pipe firmly on the flare die. Match the centers of
both the flare die and the flaring punch, and tighten flaring
punch fully.

PIPING CONNECTION TO THE UNITS
Align the center of the piping and sufficiently tighten the
flare nut with fingers.
Finally, tighten the flare nut with torque wrench
until the wrench clicks.
When tightening the flare nut with the torque wrench,
ensure that the direction for tightening follows the arrow on
the wrench.
The refrigerant pipe connection are insulated by polyure-
thane (ARMAFLEX type or similar).
