Indoor Unit Fixing
•
For detaching the indoor unit from the
installation plate, pull the indoor unit
toward you while pushing its bottom
up at the specifi ed parts.
1. Pass the pipe through the hole in the wall and hook the indoor unit on the
installation plate at the upper hook.
2. Swing the indoor unit to right and left to confi rm that it is fi rmly hooked up
on the installation plate.
3. While pressing the indoor unit onto the wall, hook it at the lower part on
the installation plate. Pull the indoor unit toward you to confi rm that it is
fi rmly hooked up on the installation plate.
Drainage
1. Run the drain hose sloped downwards.
This air conditioner has the structure designed
to drain water collected from dew, which forms
on the back of the indoor unit, to the drain pan.
Therefore, do not store the power cord and
other parts at a height above the drain guide.

NOTE
If the pipe is bent incorrectly, the indoor unit may unstably be set on the wall.
After passing the connecting pipe through the pipe hole, connect the
connecting pipes to the auxiliary pipes and wrap the facing tape around them.
CAUTION
•
Bind the auxiliary pipes (two) and connecting cable with facing tape
tightly. In case of leftward piping and rear-leftward piping, bind the
auxiliary pipes (two) only with facing tape.
•
Carefully arrange pipes so that any pipe does not stick out of the rear
plate of the indoor unit.
•
Carefully connect the auxiliary pipes and connecting pipes to one
another and cut off the insulating tape wound on the connecting pipe to
avoid double-taping at the joint; moreover, seal the joint with the vinyl
tape, etc.
•
Since dewing results in a machine trouble, make sure to insulate both
connecting pipes. (Use polyethylene foam as insulating material.)
•
When bending a pipe, carefully do it, not to crush it.

2. Put water in the drain pan and make sure that the water is drained out of
doors.
3. When connecting extension drain hose, insulate the connecting part of
extension drain hose with shield pipe.
NOTE
•
The hole should be made at a slight downward slant on the outdoor side.
CAUTION
Arrange the drain pipe for proper drainage from the unit.
Improper drainage can result in dew-dropping.

OUTDOOR UNIT
Installation Place
•
A place which provides enough spaces around the outdoor unit as shown
in the diagram
•
A place which can bear the weight of the outdoor unit and does not allow
an increase in noise level and vibration
•
A place where the operation noise and discharged air do not disturb your
neighbors
•
A place which is not exposed to a strong wind
•
A place free of a leakage of combustible gases
•
A place which does not block a passage
•
When the outdoor unit is to be installed in an elevated position, be sure to
secure its feet.
•
An allowable length of the connecting pipe is up to 15 m.
•
An allowable height level is up to 8 m (18 class) or 10 m (24 class).
•
A place where the drain water does not cause any problems
CAUTION
1. Install the outdoor unit in a location where there are no obstructions
near its air intake or air outlet.
2. When the outdoor unit is installed in a place that is always exposed to
strong winds like on the coast or on a high story of a building, secure
the normal fan operation using a duct or a wind shield.
3. Especially in windy areas, install the unit to prevent the admission of
wind.
4. Installation in the following places may result in trouble.
Do not install the unit in such places.
•
A place full of machine oil.
•
A saline-place such as the coast.
•
A place full of sulfi de gas.
•
A place where high-frequency
waves are likely to be generated,
such as from audio equipment,
welders, and medical equipment.
Strong
wind
•
Do not use the supplied drain nipple for draining water. Drain the water from
all the drain holes directly.
•
To protect the outdoor unit from snow accumulation, install a holding frame,
and attach a snow protection hood and plate.
* Do not use a double-stacked design.
