For the power supply cord and the indoor/outdoor unit connecting wires, be sure to
use the ones in compliance with the standards.

Be sure to push the core until it is hidden and pull each cable to make sure that it is
not pulled up incomplete insertion may cause a risk of burning the terminal blocks.
INDOOR UNIT INSTALLATION
•
Insert the drain hose into the wall hole sleeve C, and hook the upper part of indoor
unit on the installation plate 1. Then, move the unit to the very edge of the left side
for putting the piping easily in the back space of the indoor unit. After that, cut the part
of packing material (spacer assembly) to hook it on the back rib and lift the indoor
unit as shown in the fi gure below.

Drain hose
•
If the drain hose provided with the indoor unit is too short, connect it with drain hose

•
When connecting the drain hose to the hard vinyl chloride pipe, be sure to insert it
securely into the pipe. (Fig. 7)

•
Connect the refrigerant piping with the extension pipe B.
•
Thrust the lower part of the indoor unit into the installation plate 1.
4-7 DRAIN PIPING
•
The drain hose should point downward for easy drain fl ow. (Fig. 1)
Do not make drain piping as shown in Fig. 2 to 5.
•
If the extension drain hose has to pass through a room, be sure to wrap it with
commercially sold insulation.
CAUTION
O Use care not to make mis-wiring.
O Firmly tighten the terminal screws to prevent them from loosening.
O After tightening, pull the wires lightly to confi rm that they do not move.
O If the connecting wire is incorrectly connected to the terminal block, the unit
does not operate normally.
WARNING
O A means for disconnection of the supply with an isolation switch, or similar
device, in all active conductors shall be incorporated in the fi xed wiring.
O Never cut the power cord and connect it to other wires.
It may cause a fi re.
