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.
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.
CONDENSED WATER DISPOSAL OF OUTDOOR UNIT
There are holes on the base of Outdoor unit for condensed water to exhaust.
In order to fl ow condensed water to the drain, the unit is installed on a stand
or a block so that the unit is 100mm above the ground as shown fi gure.
Join the drain pipe to one hole.
At fi rst insert one portion of the hook to the base (Portion A), then pull the
drain pipe in the direction shown by the arrow while inserting the hook into
the base. After installation, check whether the drain pipe cling to the base
fi rmly.

When using in cold region, etc.
In cold region with severe cold climate and heavy snow, water discharged
from heat exchanger freeze on the base surface and this may affect
drainage. In such a region, remove bush on the bottom face of outdoor unit
for better drainage. When using drainpipe, consult our dealer.

WARNING
The naked part of the wire core should be 10 mm and

fi 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

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, N,
●
A and B 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 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 fi gure showing the installation of Indoor and
Outdoor units. Then fi 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.

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.

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 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.
The controller must
be hooked onto the
hook at the lower
part of the holder.
Push in the remote
controller in the
direction as shown
in fi gure beside.
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

Removal Of Air From The Pipe And Gas Leakage Inspection
Procedures of using Vacuum Pump for Air Removal
As shown in right fi gure, remove
the cap of valve core. Then,
1
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

the service valve (at 2 places) in
3
anti-clockwise direction to allow the
fl ow of coolant (using Hexagonal
Wrench key).
Remove the charge hose and
tighten the cap of valve head.
4
Check the cap's periphery if there
is any gas leakage. The task is
then completed.
Gas Leakage Inspection
