from the indoor unit correctly
on the terminal block.
•
For future servicing, give extra length to connecting wire.

to be attached at the rear right of the indoor unit.
Insert the drain hose fully into the drain pan. Check if the hose is hooked securely to
the projection of its inserting part at the drain pan.

3 Put the drain cap into the section to which the drain hose is to
be attached at the rear of the indoor unit.
Insert the screwdriver, etc. (not sharp-edged tool) into the hole at the end of the cap
and insert the cap fully into the drain pan.

•
If the drain hose provided with the indoor unit is too short, connect it with drain
hose
I
that should be provided at your site.
•
If the extension drain hose has to pass through a room, be sure to wrap it with
commercially sold insulation.

•
Thrust the lower part of the indoor unit into the installation plate

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.
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.
CAUTION
•
Use care not to make mis-wiring.
•
Firmly tighten the terminal screws to prevent them from loosening.
•
After tightening, pull the wires lightly to confi rm that they do not move.
•
If the connecting wire is incorrectly connected to the terminal block, the unit
does not operate normally.
WARNING
•
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.
•
Never cut the power cord and connect it to other wires.
It may cause a fi re.

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.
•
Peel off both ends of connecting wire (extension
wire). When too long, or connected by cutting off
the middle, peel off power supply wire to the size as
shown in the right.
•
Be careful not to contact connecting wire with piping.
•
Make earth wire a little longer than the others.
