REFRIGERANT PIPING

Piping Length & Elevation

If the pipe is too long, both 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.

Individual indoor unit can have a maximum length of 12m (39.4ft) to 15m (49.2ft), maximum elevation of 5m (16.4ft) to 8m

(26.3ft) and maximum number of bends of 10, however, total pipe length must not exceed 60 m (196.8ft).

Remark: The refrigerant pre-charged in the outdoor unit is for piping length up to 60 m (196.8ft).

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 below.

• The flared edge must be even and not cracked or

scratched.

Piping Connection To The Units

• The outdoor unit is equipped with four sets of flare joints.

Refer to table below for flare joint size and location.

• In the case where the gas pipe from the indoor unit does

not match the outdoor flare joints, four different flare

joint connectors are provided. The connector should be

connected as shown in figure.

• 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.

AIR CONDITIONER UNIT OPERATION

Dry mode

• When the air humidity is high, the unit can operate in dry

mode. Press <MODE> button and choose <DRY>.

• If the room temperature is 2°C/35.6°F higher than the set

temperature, the air conditioner will operate under cooling

mode until it reaches within the 2°C/35.6°F range of

difference compared to the set temperature before it

converts to dry mode.

• If the room temperature is within the 2°C/35.6°F range of

difference compared to the set temperature, it will

directly operate under dry mode.

• The indoor fan will operate at super low speed under dry

mode.

Horizontal Air Flow Control

• For more effective air circulation, you can manually ad-

just the air discharge grille to the left or right.

• During cool mode operation and dry mode operation, do

not direct the air discharge louver downwards for too long.

If operating continues in this way, condensation may oc-

cur on the louver, thus resulting in drippings.

Frost prevention

• When the air filter is dirty, the evaporating temperature

will decrease and eventually cause frosting.

• When this happens, the compressor will reduce its running

speed to prevent freezing. If the coil temperature is still

very low, the compressor will stop.

Fan speed and rated cooling capacity

• The rated cooling capacity is provided at the maximum

fan speed.

• The cooling capacity is lower when the unit is operating at

MEDIUM and LOW fan speed.

Turbo function

• If higher cooling or heating is required during operation,

press "Turbo" button on the remote control to increase the

cooling or heating capacity to maximum.

• This function will operate for 15 minutes before it resume

to the actual setting.

• The fan noise may be higher if the unit operates in "Turbo"

mode.
