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:

REFRIGERANT PIPING

Outdoor Unit

Indoor Unit

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.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

R410A is a new HFC refrigerant which does not damage the

ozone layer. The working pressure of this new refrigerant is

1.6 times higher than conventional refrigerant (R22), thus

proper installation / servicing is essential.

•

Never use refrigerant other than R410A in an air

conditioner which designed to operate with R410A.

•

POE oil is used as lubricant for R410A compressor, which

is different from the mineral oil used for R22 compressor.

During installation or servicing, extra precaution must

be taken not to expose the R410A system too long to moist

air. Residual POE oil in the piping and components can

absorb moisture from the air.

•

To prevent mischarging, the diameter of the service port

on the flare valve is different from that of R22.

•

Use tools and materials exclusively for refrigerant R410A.

Tools exclusively for R410A are manifold valve, charging

hose, pressure gauge, gas leak detector, flare tools, torque

wrench, vacuum pump and refrigerant cylinder.

•

As an R410A air conditioner incurs higher pressure than

R22 units, it is essential to choose the copper pipes

correctly. Never use copper pipes thinner than 0.8mm even

though they are available in the market.

•

If the refrigerant gas leakage occurs during installation /

servicing, be sure to ventilate fully. If the refrigerant gas

comes into contact with fire, a poisonous gas may occur.

•

When installing or removing an air conditioner, do not

allow air or moisture to remain in the refrigerant cycle.

VACUUMING AND CHARGING

Purging The Piping And The Indoor Unit

Except for the outdoor unit which is pre-charged with

refrigerant, the indoor unit and the refrigerant

connection pipes must be air-purged because the air

containing moisture that remains in the refrigerant cycle may

cause malfunction of the compressor.

•

Remove the caps from the valve and the service port.

•

Connect the center of the charging gauge to the vacuum

pump.

•

Connect the charging gauge to the service port of the

3-way valve.

•

Start the vacuum pump. Evacuate for approximately

30 minutes. The evacuation time varies with different

vacuum pump capacity. Confirm that the charging gauge

needle has moved towards -760mmHg.

Caution

•

If the gauge needle does not move to -760mmHg, be sure

to check for gas leaks (using the refrigerant

detector) at flare type connection of the indoor and outdoor

unit and repair the leak before proceeding to the next step.

•

Close the valve of the charging gauge and stop the vacuum

pump.

•

On the outdoor unit, open the suction valve (3 way) and

liquid valve (2 way) (in anti-clockwise direction) with 4mm

key for hexagon sacked screw.

port.

•

Remove the service port cap.

•

Connect the low pressure side of the charging gauge to the

suction service port center of the cylinder tank and close

the high pressure side of the gauge. Purge the air from the

service hose.

•

Start the air conditioner unit.

•

Open the gas cylinder and low pressure charging valve.

•

When the required refrigerant quantity is pumped into the

unit, close the low pressure side and the gas cylinder valve.

•

Disconnect the service hose from service port. Put back the

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/3.6°F higher than the set

temperature, the air conditioner will operate under

cooling mode until it reaches within the 2°C/3.6°F range

of difference compared to the set temperature before it

converts to dry mode.

• If the room temperature is within the 2°C/3.6°F range

of difference compared to the set temperature, it will

directly operate under dry mode.

• The unit will operate at LOW speed under dry mode.

Heat Mode (for heat pump unit only)

• When the unit is switched on from cold start or

defrosting cycle, the indoor fan will start to operate only

after the coil reaches the desired temperature.

• When the set temperature is achieved, the indoor fan

will operate until the coil cannot provide anymore

additional heat.

Air Flow Control

• For more effective air circulation, you can manually

adjust 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 occur on the louver, thus resulting in drippings.

Overheating Protection (for heat pump unit only)

• In case the internal and/or the external temperature is

too high, or that the filter is dirty and clogged up, the

refrigerant may be overheated. The compressor will cut

out when the condensing temperature reaches 62°C/

143.6°F.

Frost Prevention

• When the air filter is dirty, the evaporating temperature

will decrease and eventually cause frosting.

• If the evaporating temperature reaches -1°C/33.8°F, the

unit will trip.

Fan Speed And Rated Cooling Capacity

• The rated cooling capacity is provided at the HIGH fan

speed.

• The cooling capacity is lower when the unit is operating

at MEDIUM and LOW fan speed.

Notes On Flaps And Louvers Angles

• When “SWING button” is selected, the flaps swinging

range depends on the operation mode. (See the figure.)

ATTENTION

• Always use a remote controller to adjust the flaps angle.

If you attempt to move it forcibly with hand when it

is swinging, the mechanism may be broken.

• Be careful when adjusting the louvers. Inside the air

outlet, a fan is rotating at a high speed.
