3. SELECTING THE INSTALLATION LOCATION
• Where it is not exposed to strong wind.
• Where airflow is good and dustless.
• Where it is not exposed to rain and direct sunshine.
• Where neighbours are not annoyed by operation sound or hot air.
• Where rigid wall or support is available to prevent the increase of operation sound or vibration.
• Where there is no risk of combustible gas leakage.
• When installing the unit at a high level, be sure to fix the unit legs.
• Where it is at least 3 m away from the antenna of TV set or radio. Operation of the air conditioner may
interfere with radio or TV reception in areas where reception is weak. An amplifier may be required for the
affected device.
• Install the unit horizontally.
• Please install it in an area not affected by snowfall or blowing snow. In areas with heavy snow, please install
a canopy, a pedestal and/or some baffle boards.
Note:
It is advisable to make a piping loop near outdoor unit so as to reduce vibration transmitted from there.
WARNING:
Be sure to install the unit in a place that well sustains its weight.
Installing in a place with less strength may result in a unit falling, causing a risk of injury.
CAUTION:
Avoid the following places for installation where air conditioner trouble is liable to occur.
••
••
• Where flammable gas could leak.
••
••
• Where there is much machine oil.
••

• Salty places such as the seaside.
••
••
• Where sulfide gas is generated such as
a hot spring.
••
••
• Where there is high-frequency or wire-
less equipment.
Note:
When operating the air conditioner in low outside temperature, be sure to follow the instructions de-
scribed below.

• Never install the outdoor unit in a place where its air inlet/outlet side may be exposed directly to
wind.
