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.

Procedures of Wiring
1. Installation procedure and notice
Especially, the selection of installation place need great
care for the split type air conditioner, because it is
very diffi cult to move from place to place after the fi rst
installation.
1.1 Wiring
(1) Connect the electrical wiring between the Indoor and
Outdoor unit, as shown in Fig. 1-1. Never connect
the wiring by mistake.
In case of wrong connection, the unit does not
operate properly and it may cause malfunction.
(2) The connecting cord must be fi xed by the band
which is located near the terminal board.
1.2 Connection of the connecting cords and
power cord
(1) Cut off the connecting cord, the power cord and
strip the insulation of the wire, as shown in Fig. 1-2.
(2) Connect the connecting cord and power cord to the
terminal board. (Fig. 1-3)
(3) Fix the connecting cords and power cord with steel
band certainly. (Fig. 1-3)
Detail of Cutting the Connecting Cord
Fig. 1-2
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
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
●
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.
