OUTDOOR UNIT
●
Please mount the outdoor unit on stable ground to prevent
vibration and increase of noise level.
●
Open the side plate by unscrewing the screws as shown below.
Gas Leakage Inspection
Please use gas leakage detector to check if leakage occurs
at the connection of Flare nut as shown on the right.
If gas leakage occurs, further tighten the connection to
stop leakage.

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 fl aring, please
put on the fl are nut.

Run the vacuum pump for about 10~15
minutes, then completely tighten the “Lo” knob
and switch off the vacuum pump.

Completely unscrew the spindle of the
service valve (at 2 places) in anti-clockwise
direction to allow the fl ow of refrigerant (using
Hexagonal Wrench key).
Re-cap the service valve and tighten using
wrench. Check the cap’s periphery if there is
any gas leakage. The task is then completed.
Remove the charge hose and tighten the cap
of valve core. Check the cap’s periphery if
there is any gas leakage.

You may not be able to close the side
cover due to the connecting cord, under
such situation, please press against the
wall of side cover to fi x it.
●
Be sure that the hooks (6 places) are
plugged in.
Otherwise, water leakage may occur and
this causes short circuit or faults.
Checking for the electric source and the voltage range
●
Before installation, the power source must be checked and necessary wiring work must be completed. To make the proper
wiring capacity, use the wire gauges list below for the lead-in from a pole transformer and for the wiring from a switch board
of fuse box to the outlet in consideration of the locked rotor current.
●
Investigate the power supply capacity and other electrical conditions at the installation location.
Depending on the model of room air conditioner to be installed, request the customer to make arrangements for the necessary
electrical work etc.
The electrical work includes the wiring work up the outlet. In localities where electrical conditions are poor, use of a voltage
regulator is recommended.

Procedures of Wiring
Power is supplied from Outdoor Unit
●
The naked part of the wire core should be 10 mm and
fi x it to the terminal tightly. 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 power cables approved from the
authorities in your country. For example in Germany:
Cable type: NYM 3x1.5mm
2
, (fuse = 20A time delay)
●
Please refer to the installation manual for wire connection
to the terminals of the units. The cabling must meet the
standards of electrical installation.
●
There is a AC voltage of 220V between the L and N
terminals. Therefore, before servicing, be sure to remove
the plug from the AC outlet or switch off the main switch.
WARNING
Wiring Of The Indoor Unit
●
For wire connection of the Indoor unit, you need to remove
front panel and electrical cover.
Method to remove front panel
●
Refer to “How to Remove The Front Cover”.
Method to remove electrical cover
●
Remove the screw and electrical cover.
●
Insert the connecting cord (A,B,C,D) from the bottom of
unit.
●
Fixed the wire to terminal wires fi rmly as shown in Figure

●
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 fi gure of installation of both the indoor and
outdoor units. Then fi x their position with holders.
●
To enhance 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.
Installation Of Remote Control

●
The remote controller can be placed in its holder which is
fi xed 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 fi xed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the fl orescent 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 fi re.
(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 fi x 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.
