OUTDOOR UNIT
Installation Place
• 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.

• A place where the drain water does not raise any problems
CAUTION
• Do not scratch the inner surface of the flared part when removing burrs.
• Flare processing under the condition of scratches on the inner surface of
flare processing part will cause refrigerant gas leak.
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.
Precautions about Installation in Regions
with Snowfall and Cold Temperatures
• 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.
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 sulfide gas
• A place where high-frequency waves are
likely to be generated as from audio
equipment, welders, and medical equipment
