Removal Of Air From The Pipe And Gas Leakage Inspection
Preparation of Pipe
1
●
Use a pipe cutter to cut the copper pipe.
●
Jagged edge will cause leakage.
●
Point the side to be trimmed downwards during trimming to prevent copper chips from
entering the pipe.
●
Before flaring, please put on the hexagon screw cap.

Then tighten the flare nut.
When the meter reaches –101KPa (–76cmHg)
during pumping, fully tighten the shuttle.
As shown in figure on the right, remove
the cap of valve head and valve core
and then connect them to the vacuum
pump and sub-division valve.
Fully tighten the “Hi” shuttle of the sub-
division valve and completely unscrew
the “Lo” shuttle. Run the vacuum pump
for about 10–15 minutes, then completely
tighten the “Lo” shuttle and switch off
the vacuum pump.

Completely unscrew the spindle of the
service valve (at 2 places) in anti-
clockwise direction to allow the flow of
coolant (using Allen key).

Remove the connection pipe and tighten
the cap of valve head. The task is then
completed.

Gas Leakage Inspection
Please use gas leakage detector to check if leakage occurs at
the connection of hexagon screw nut as shown on the right.
If gas leakage occurs, further tighten the connection to stop
leakage.

CONNECTION OF POWER CORD
●
The naked part of the wire core should be 14 mm and the insulated part of the wire must be push into the terminal for 3 – 4 mm.
Then try to pull the individual wire to check if the contact is tight. Improper insertion may burn the terminal.
●
Be sure to use only wire specified for the use of air-conditioner.
●
Please refer to the installation manual for wire connection and the wiring technique should meet the standards of electrical
installation.
●
There is a AC voltage drop between the AB terminals if the power is on. Therefore, be sure to remove the plug from its socket.

●
The connected terminals should be completed sealed with
heat insulator and then tied up with rubber strap.
●
Please tie the pipe and power line together with plastic tape
as shown in the figure of installation of both the indoor and
outdoor units. Then fix their position with holders.
●
To enchance the heat insulation and to prevent water
condensation, please cover the outdoor part of the drain hose
and pipe with insulation pipe.
●
Completely seal any gap with putty.

●
The remote controller can be placed in its holder which is
fixed on wall or beam.
●
To operate the remote controller at its holder, please ensure
that the unit can receive signal transmitted from the controller
at the place where the holder is to be fixed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the florescent light. Therefore, during
the installation of the remote control holder, please switch on
the light, even during day time, to determine the mounting
location of the holder.
CAUTION
!
●
The earth line terminal of the outdoor unit is below the
service valve.
●
To avoid short circuit, it is necessary to install circuit breaker
depending on the mounting location of the unit.
●
Do not place earth line near the following objects:
(1) Water pipe
(2) Gas pipe – There is danger of catching fire.
(3) The earth line of lightning conductor and telephone —
short circuit may occur during lightning.
Power Source
WARNING
!
●
Do not alter the plug of power cord.
Do not make extension to the power cord.
CAUTION
!
●
Please use a new socket. Accident may occur due to the
use of old socket because of poor contact.
●
Please plug in and then remove the plug for 2 – 3 times.
This is to ensure that the plug is completely plugged into
the socket.
●
Keep additional length for the power cord and do not render
the plug under external force as this may cause poor
contact.
●
Do not fix the power cord with U-shape nail.
Operation Test
●
Please ensure that the air conditioner is in normal operating
condition during the operation test.
●
Explain to your customer the proper operation procedures
as described in the user’s manual.

as shown in figure below.
WARNING
●
You may not be able to close the side cover
due to the connecting cord, under such
situation, please press against the wait of
side cover to fix it.
●
Be sure that the hooks (2 places) are
plugged in.
Otherwise, water leakage may occur and this
causes short circuit or faults.
●
THIS APPLIANCE MUST BE EARTHED.
