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

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 and Installing In Cold Areas
When the air conditioner is used in low temperature and in snowy
conditions, water from the heat exchanger may freeze on the base
surface to cause poor drainage. When using the air conditioner
in such areas, do not install the bushings. Keep a minimum of
250mm between the drain hole and the ground. When using the
drain pipe, consult your sales agent.
For more details, refer to the installation Manual for Cold Areas.

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 wire specifi ed for the use of air-conditioner.
●
Please refer to the manual for wire connection and the wiring technique
●
should meet the standard of the electrical installation.
There is an AC voltage drop between the LN terminal if the power is
●
on. Therefore, be sure to remove the plug from its socket.

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.

Wiring of The Outdoor Unit
Please remove the side plate for wire connection.
●
If you cannot attach the side plate due to the connection cord, please press the connecting cord in
●
the direction to the front panel to fi x it.
!
Be sure that the hooks of the side plate is fi xed in certainly. Otherwise water leakage may occur
●
and this causes short circuit or faults.
WARNING
The connecting cord should not touch to service valve and pipes. (It becomes high temperature in
●
heating operation.)
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 gauge list below for the wiring from house distribution fuse box to the
outdoor unit in consideration of the locked rotor current.
Investigate the power supply capacity and other electrical conditions at the
●
installing 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 unit . In
localities where electrical conditions are poor, use of a voltage regulation
is recommended.
Install outdoor for the room air conditioner within the reaching range of the
●
line cord.
