Procedures of Wiring
CONNECTION OF POWER CORD
WARNING
!
Power supply shall be connected at the rated voltage, otherwise the unit will be broken or could
not reach the speci ed capacity.
Checking for the electric source and
the voltage range
O
Before installation, the power source must be checked and necessary
wiring work must be completed. To make the wiring capacity proper,
use the wire gauge list below for the wiring from a switch board of fuse
box to the outdoor unit in consideration of the locked rotor current.
IMPORTANT
O
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.
O
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)
O
Please refer to the installation manual for wire connection to the terminals of the units. The
cabling must meet the standards of electrical installation.
O
There is a AC voltage of 220-240V between the L and N terminals (indoor unit) and 380V
between R,S,T,N terminals (outdoor unit). Therefore, before servicing, be sure to remove the
power cord from the AC outlet or switch off the main switch.
O
Do not make any connection in the middle of the connecting power cord. It may cause the
wire over heated, emit smoke and re.
WARNING
!
WARNING
O
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.
O
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.
O
The connecting cord should not touch to service
valve and pipes. (It becomes high temperature in
heating operation.)
O
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.

Insulation And Maintenance Of Pipe Connection
1
O
The connected terminals should be completed sealed with
heat insulator and then tied up with rubber strap.
O
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.
O
To enchance the heat insulation and to prevent water
condensation, please cover the outdoor part of the drain hose
and pipe with insulation pipe.
O
If room humidity is high, cover the connecting pipe with
additional 5mm thickness insulator. This insulator shall be
purchased from eld.
O
Completely seal any gap with putty.
Power Source And Operation Test

Operation Test
O
Please ensure that the air conditioner is in normal operating
condition during the operation test.
O
Explain to your customer the proper operation procedures
as described in the user’s manual.
Installation Of Air Panel
3
O
Carefully read through the procedures of proper installation
before starting installation work.
CAUTION
!
O
Please use a new socket. Accident may occur due to the
use of old socket because of poor contact.
O
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.
O
Keep additional length for the power cord and do not
render the plug under external force as this may cause
poor contact.
O
Do not x the power cord with U-shape nail.

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.
Procedures of using Vacuum Pump for Air Removal
As shown in gure 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 ow of
coolant (using Hexagonal Wrench key).
3
Remove the Charge hose and tighten
the cap of valve head. The task is then
completed.

O
Use a pipe cutter to cut the copper pipe.
O
Jagged edge will cause leakage.
O
Point the side to be trimmed downwards during trimming to prevent copper chips
from entering the pipe.

Please be careful when bending the copper pipe.
O
Applied frozen grease to the connection points and then screw in manually. After
that, use a torque wrench to tighten the connection.
Please mount the outdoor

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.
Please face this side

unit to the wall.
Please
remove side

CAUTION
!
Please make sure to remove
all spacers inside the unit.
Open the Top, Back and

CONDENSED WATER DISPOSAL OF OUTDOOR UNIT
There are holes on the base of Outdoor unit for condensed water
to exhaust.
In order to 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 gure. Join the drain pipe to one hole.
At 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 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.
