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, the system must
be vacuumed. Generally do not remove plastic, rubber
plugs and brass nuts from the valves, À ttings, tubing and
coils until it is ready to connect suction or liquid line into
valves or À ttings.

If any brazing work is required, ensure that nitrogen gas

•
is passed through coil and joints while the brazing work
is being done. This will eliminate soot formation on the
inside wall of copper tubings.

Cut the pipe stages by stages, advancing the blade of pipe

•
cutter slowly. Extra force and a deep cut will cause more
distortion of pipe and therefore extra burr. See Figure A.

Remove burrs from cut edges of the pipes with remover. See

•
Figure B. Hold the pipe on top position and burr remover
at lower position to prevent metal chips from entering the
pipe. This will avoid unevenness on the Á are faces which
will cause gas leak.

Insert the Á are nuts, mounted on the connection parts of

•
both the indoor unit and outdoor unit, into the copper
pipes.

The exact length of pipe protruding from the top surface

•
of the swaging block is determined by the Á aring tool. See
Figure C.

Fix the pipe À rmly on the swaging block. Match the centers

•
of both the swaging block and the Á aring punch, then
tighten the Á aring punch fully.

Piping Connection To The Units

Align the center of the piping and tighten the Á are nut

•
sufÀ ciently with À ngers. See Figure D.

Finally, tighten the Á are nut with torque wrench until the

•
wrench clicks.

When tightening the Á are nut with the torque wrench,

•
ensure that the tightening direction follows the arrow
indicated on the wrench.

The refrigerant pipe connection are insulated by closed

•
cell polyurethane.

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system.

Vacuuming 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. ConÀ rm 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 Á are
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.

Charge Operation

This operation must be done by using a gas cylinder and a
precise weighing machine. The additional charge is topped-up
into the outdoor unit using the suction valve via the service
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
service port cap.

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 À lter 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 À lter 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 Á aps swinging

•
range depends on the operation mode. (See the À gure.)

ATTENTION

Always use a remote controller to adjust the Á aps 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.
