• A place which provides the 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.
• The allowable length of the connecting pipe.
• The allowable heigth of outdoor unit installation site.
• A place where the drain water does not raise any problems
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

CAUTION
When the outdoor unit is installed in a place where the drain water might
cause any problems, Seal the water leakage point tightly using a silicone
adhesive or caulking compound.
CAUTION
1. Install the outdoor unit without anything blocking the air discharging.
2. When the outdoor unit is installed in a place always exposed to strong
wind like a coast or on a high storey of a building, secure the normal
fan operation using a duct or a windshield.
3. In particularly windy areas, install the unit such as to avoid 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
as from audio equipment, welders,
and medical equipment
