Insulation And Maintenance Of Pipe Connection
1
●
The connected terminals should be completely 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 gure showing the installation of Indoor and
Outdoor units. Then x 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
●
The remote controller can be placed in its holder which is
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 xed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the uorescent 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 And Operation Test
3
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 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.
The controller should
be insert from top into
bottom side of the
holder as shown in
gure beside.
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.
3
Procedures of using Vacuum Pump for Air Removal
As shown in right gure, 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.
2
Completely unscrew the spindle of
the service valve (at 2 places) in anti-
clockwise direction to allow the ow of
coolant (using Hexagonal Wrench key).
3
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.

In case of removing are nut of an Indoor unit, rst remove a nut
of small diameter side, or a seal cap of big diameter side will y
out. Prevent water from entering into the piping when working.
When the meter reaches - 101KPa
(-76cmHg) during pumping, fully
tighten the shuttle.
When pumping starts, slightly loosen the
are nut to check of air sucked in. Then
tighten the are nut.

WARNING
●
If you cannot attach the side plate due to the connecting
cord, please press the connecting cord in direction to the
front panel to x it.
●
Be sure that the hooks of the side plate is xed in certainly.
Otherwise water leakage may occur and this causes short
circuit or faults.
●
The naked part of the wire core should be 10 mm and 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
.
●
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 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.
●
Do not make any connection in the middle of the connecting cable. It may cause the wire over
heated, emit smoke and re.
●
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 outdoor. In localities
where electrical conditions are poor, use of a voltage regulation is
recommended.
●
Install outlet for the room air conditioner within the reaching range
of the line cord.
●
THIS APPLIANCE MUST BE EARTHED.
