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.

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.
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.

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”.
CAUTION
!
Please make sure to remove all spacers inside the unit.
●
Open the Top, Back and Side cover of the unit.
●
Pull out the spacers inside.
(Spacers are only for transportation purpose).
If not remove, vibration and noise will occur.
Top cover
Back cover
Side cover
The controller should be
insert from top into bottom
side of the holder as shown
in figure below.
●
The naked part of the wire core should be 10 mm and fix 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.

Procedures of using Vacuum Pump for Air Removal
As shown in right figure, remove the cap
of valve core. Then, connect the charge
hose. Remove the cap of valve head.
Connect the vacuum pump adapter to
the vacuum pump and connect the
charge hose to the adapter.
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.
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).
Remove the charge hose and tighten the
cap of valve head. Check the cap’s
periphery if there is any gas leakage.
The task is then completed.
