INSTALLATION OF THE OUTDOOR UNIT
1. Precautions for Selecting a Location
Choose a place solid enough to bear the weight and vibration of the unit, where the operating sound will not be
amplified.
Choose a location where the hot air discharged from the unit or the operating sound will not cause a nuisance to the
neighbors of the user.
Avoid locations, such as near bedrooms, where the operating sound may cause disturbance.
There must be sufficient space to carry the unit into and out of the site.
There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.
The site must not be prone to flammable gas leaks in the surrounding area.
Install units, power cords and inter-unit wire at least 10ft (3m) away from television and radio sets. (This is to prevent
interference to images and sounds. Noise may be produced even if they are more than 10ft (3m) away depending on radio
wave conditions.)
In coastal areas or other places with a salty atmosphere or one containing sulfate gas, corrosion may shorten the life of
the air conditioner.
Since water will flow from the drain of the outdoor unit, do not place under the unit anything which must be kept away
from moisture.
NOTE
Cannot be installed suspended from a ceiling or stacked.
! CAUTION
When operating the air conditioner in a low outdoor ambient temperature, be sure to follow the
instructions described below.
To prevent exposure to wind, install the outdoor unit with its suction side facing the wall.
Never install the outdoor unit at a site where the suction side may be exposed directly to
wind.
To prevent exposure to wind, it is recommended to install a baffle plate on the air discharge
side of the outdoor unit.
In heavy snow areas, select an installation site where the snow will not affect the unit.
If there is a likelihood of snow accumulating on the outdoor unit, attach a snow protection
hood.
In high humidity areas or heavy snow areas, it is recommended to attach a drain pan heater to
prevent ice build-up from the bottom frame.
