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:

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.

English

• All wires must be firmly connected.

• All wires must not touch the refrigerant piping, compressor

or any moving parts of the fan motor.

• The connecting wires between the indoor unit and the

outdoor unit must be clamped on the wire clamps as shown

in the figure.

• The power supply cord must be equivalent to H05RN-F

(245IEC57) which is the minimum requirement.

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 condi-

tioner 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.

SPECIAL PRECAUTIONS WHEN DEALING WITH R407C UNIT

• R407C is a zeotropic refrigerant mixture which has zero

ozone depletion potential and thus conformed to the

Montreal Protocol regulation. It requires Polyol ester oil

(POE) oil for its compressor's lubricant. Its refrigerant

capacity and performance are about the same as the

refrigerant R22.

• POE oil is used as lubricant for R407C 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 R407C system too long to moist

air. Residual POE oil in the piping and components can

absorb moisture from the air.

• Refrigerant R407C is more easily affected by dust of

moisture compared with R22, make sure to temporarily

cover the ends of the tubing prior to installation.

• 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 cor-

rectly. 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.

• No additional charge of compressor oil is permitted.

• No other refrigerant other than R407C.

• Tools specifically for R407C only (must not be used for

R22 or other refrigerant)

i) Manifold gauge and charging hose

ii) Gas leak detector

iii) Refrigerant cylinder/charging cylinder

iv) Vacuum pump c/w adapter

v) Flare tools

vi) Refrigerant recovery machine

• Filter-dryer must be installed along the liquid line for all

R407C air conditioners. This is to minimise the contamination

of moisture and dirt in the refrigerant system. Filter-dryer

must be of molecular sieve type. For a heat-pump system,

install a two-way flow filter dryer along the liquid line.

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 changing 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.

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.

Horizontal 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.

Hot Keep (for heat pump only)

• During compressor cut off, the indoor fan can be

switched to

(i) ON (default) or

(ii) OFF or

(iii) Interval on and off

by setting the slide switch shown in the diagram.

• The switch is located at the front frame cover (next to

the ON/OFF switch).

NOTE : When the option is selected, the power supply of

the unit need to be reset in order to activate the

function.

Overheating protection (for heat pump unit only)

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

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.

• The LED light will blink to indicate that the filter is

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

the unit will trip and defrost.

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.

1. The electrostatic air purifying and deodorizing filter

should be replaced once every 6 months or when the

filter changes color to brownish, whichever is sooner.

2. Used dusty filters should be disposed and shouldn't be

reused, even if it has been cleaned and washed.

3. The filter is a consumable part which you can purchase

from your air conditioner dealer.

4. Use the new filter immediately once it has been taken

out from its sealed packing. Do not unpack the new

filter too early before it is actually used as this may

decrease its deodorizing effect.

! Warning

• Disconnect from the main power supply before servicing the air conditioner unit.

• DO NOT pull out the power cord when the power is ON. This may cause serious electrical shocks which may result

in fire hazards.

AUTO RANDOM RE-START FUNCTION

If there is a power cut when the unit is operating, it will automatically resume the same operating mode when the power is

restored. (Applicable only to units with this feature.)

! Caution

Before turning off the power supply, set the remote controller’s ON/OFF switch to the “OFF” position to prevent the

nuisance tripping of the unit.

If this is not done, the unit’s fans will start turning automatically when power resumes, posing a hazard to service

personnel or the user.

HOW TO INSTALL

The unit with 3 phase Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is

fitted to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase protector

operates, and the unit will not start. This devise is located in the control box of the outdoor unit.

The following table shows the LED indicator light for phase protector under normal operation and fault conditions.
