!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 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 units panel is closed after service or installation.

Unsecured panels will cause the unit to operate noisily.

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 or 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 THE AIR CONDITIONER UNIT IN A LAUNDRY ROOM.

Service Access

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/113°F).

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.

If the orifice pipe cannot be connected directly to the liquid valve due to space constraint, it can be connected in between of the

liquid pipe.

Steps:

1. Flare the liquid pipe and connect it to the liquid valve.

2. Braze an additional “Male” joint to the liquid pipe.

3. Connect the “Female” nut of the Orifice pipe to

the“Male” joint.

4. Flare another liquid pipe and connect it to the “Male”

joint of the orifice pipe.

Steps:

1. Braze an additional “Male” joint

to the liquid pipe.

3. Flare another liquid pipe and

connect it to the “Male” joint

of the orifice pipe.

Air Flow

Direction

Higher Than

Eye Level

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.

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).

Routing of piping

Remove the screw holding the front panel.

1/50 Inclination

Right & rear side routing

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.

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.

Piping length and 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:

Remark: The refrigerant pre-charged in the outdoor unit

is for piping length up to 7.62m/25ft.

REFRIGERANT PIPING

Outdoor unit

Indoor unit

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.

!Caution

An orifice is used as expansion device in WM301 cooling only unit. It is fixed in the liquid pipe in the indoor unit.

Piping connection to the units

• Align the center of the piping and tighten the flare nut

sufficiently with fingers.

• Finally, tighten the flare nut with the torque wrench

until the wrench clicks.
