2. Selecting the installation location
2.1. Outdoor unit
• Where it is not overly exposed to strong winds.
• Where airflow is good and dustless.
• Where neighbors 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.
• If installing the unit in a location high above the ground, 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. Opera-
tion 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 baffle boards.
Note:
• It is advisable to make a piping loop near outdoor unit so as to reduce vibration.
• For increased efficiency, install the outdoor unit in a location where continuous
direct sunlight or excessive water can be avoided as much as possible.
