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.

SUCTION

LIQUID

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.

Center distance of axle (see drawing below)

Provide clearance for servicing ease and optimal air flow as

shown in the diagram.

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

of the unit. Remove obstacles which block air intake or

discharge.

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).
