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.
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.
Arrange the drain pipe for proper drainage from the unit.
Improper drainage can result in dew-dropping.
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.

• 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

of refrigerant for every additional meter of the pipe length for all models.
• The allowable height of outdoor-unit installation site is up to 10 m.
• A place where the drain water does not raise any problems
