OUTDOOR UNIT
●
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.
●
Open the side plate by unscrewing the screws as shown below.
Removal Of Air From The Pipe And Gas Leakage Inspection
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.

Insulation And Maintenance Of Pipe Connection
1
●
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 figure showing the installation of 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.
Installation Of Remote Controller
2
Power Source And Operation Test
3
●
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.
Power Source
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.

Procedures of using Vacuum Pump for Air Removal
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 manifold valve.
Fully tighten the “Hi” shuttle of the
manifold 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.
2
Completely unscrew the spindle of the
service valve (at 2 places) in anti-
clockwise direction to allow the flow of
coolant (using Hexagonal Wrench key).
3
Remove the Charge hose and tighten
the cap of valve head. The task is then
completed.

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 flare nut.

WARNING
●
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 fix it.
●
Be sure that the hooks (2 places) are plugged in.
Otherwise, water leakage may occur and this causes short
circuit or faults.
●
The naked part of the wire core should be 10 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.
How to Remove the Front
Cover
●
Open the cover and remove the screw.
●
After open the front panel, remove the screw and open
the
cover , disconnect the wire connector .
●
Remove the filter, release the axis by pulling the center
portion of front cover in the direction of arrow .
●
Push vertical air deflector handle to the right or left side.
●
After raise the front cover from bottom side as , release
the front cover by pull the right or left sides as .
How to Install the Front Cover
●
Insert the two hooks at the upper side certainly.
●
Open Front Panel, push the center down in the direction
of the arrow to insert the axis at the center of the front
cover into the hook at the outlet frame.
●
Connect the wire connetor , fixed the screw and cover
and .
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 regulation is
recommended.
