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.
●
When removing side cover, please pull the handle after undoing the

Procedures of using Vacuum Pump
for Air Removal
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 aring, please put on the are nut.

WARNING
●
If you cannot attach the side cover due to the connecting cord, press
the connecting cord in direction to the front panel to x it.
●
Be sure that the hooks of the side cover is xed in certainly. Otherwise
water leakage may occur and this causes short circuit or faults.
●
The connecting cord should not touch to service valve and pipes. (It
becomes high temperature in heating operation.)
●
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
(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 220-240V 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.
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 wiring capacity proper, 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 main switch and
outdoor unit 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 outdoor. In localities
where electrical conditions are poor, use of a voltage regulation is
recommended.

Please be careful when bending the copper pipe.
●
Screw in manually while adjusting the center. After that, use of torque wrench to
tighten the connection.

In case that power is supplied from Indoor Unit
Please face this side (suction side)
of the unit to the wall.

CAUTION
!
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.

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
Power Source And Operation Test
3
●
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
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.

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.
CAUTION
!
In case of removing Flare nut of a cooling unit, rst remove a nut of
small diameter side, or else seal cap of big diameter side will y out.
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” knob of the manifold
valve and completely unscrew the “Lo” knob.
Run the vacuum pump for about 10~15
minutes, then completely tighten the “Lo” knob
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 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.
