Please mount the Outdoor unit on stable ground to prevent
●
vibration and increase of noise level.
Decide the location for piping after sorting out the different
●
types of pipe available.
When removing side cover, please pull the handle after undoing
●
the hook by pulling it downward.
Please face this side (suction side)
of the unit to the wall.
Please remove side cover
when connecting the piping
and connecting cord.

CAUTION
Please make sure to remove all spacers inside the unit.
Open the Top, Back, Side cover and Cabinet of the unit.

WARNING
THIS APPLIANCE MUST BE EARTHED.
●
Power supply shall be connected at the rated voltage, otherwise the unit will be
broken or could not reach the specifi ed capacity.
Procedures of Wiring
WARNING
!
The naked part of the wire core should be 10 mm and fi xed 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 = 16A time delay)
Please refer to the following for wire connection to the terminals of the units. The cabling
●
must meet the standards of electrical installation.
There is a AC voltage of 220~230V 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.

Insulation And Maintenance Of Pipe Connection
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 vinyl tape as
●
shown in the fi gure showing the installation of 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.

Preparation of Pipe
Use a pipe cutter to cut the copper pipe.

must be completed. To make the wiring capacity proper, use the wire gauges list
below for the lead-in from a pole transformer and for the wiring from a switch

Installation Of Remote Controller
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.
The controller should
be insert from top into
bottom side of the
holder as shown in
fi gure beside.

Please refer to Instruction Manual – "Removing the Front Panel" under "Cleaning
of Front Panel".
Method to remove electrical cover
●
Remove the screw and electrical cover.
●
Insert the connecting cord (A, B) from the back of unit.
●
Fixed the wire to terminal wires fi rmly as shown in fi gure.

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

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.
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.
Connect the earth cord

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.
Install outlet for the room air conditioner within the reaching
