1-4. SELECTING THE INSTALLATION LOCATION
• Where it is not exposed to strong wind. If the outdoor unit is exposed to a
wind during defrosting, the defrosting time will be longer.
• Where airflow is good and dustless.
• Where rain or direct sunshine can be avoided as much as possible.
• Where neighbours are not annoyed by operation sound or hot (or cool) 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, be sure to secure the unit legs.
• Where it is at least 10 ft. (3 m) away from the antenna of TV set or radio. Op-
eration 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.

Note:
When operating the air conditioner in low outside temperature, be sure to
follow the instructions described below.
• Never install the outdoor unit in a place where its air inlet/outlet side may
be exposed directly to wind.
• To prevent exposure to wind, install the outdoor unit with its air inlet side
facing the wall.
• To prevent exposure to wind, it is recommended to install a baffle board on
the air outlet side of the outdoor unit.
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 hot spring, sewage, waste water.
• Where there is high-frequency or wireless equipment.
• Where there is emission of high levels of VOCs, including phthalate com-
pounds, formaldehyde, etc., which may cause chemical cracking.
