Precautions for Selecting the Location
1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified.
2) Choose a location where the hot air discharged from the unit or the operation noise will not cause a nuisance to the neighbors of
the user.
3) Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.
4) There must be sufficient spaces for carrying the unit into and out of the site.
5) There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.
6) The site must be free from the possibility of flammable gas leakage in a nearby place.
7) Install units, power cords and inter-unit wire at least 10 feet (3m) away from television and radio sets. This is to prevent
interference to images and sounds. (Noises may be heard even if they are more than 10 feet (3m) away depending on radio wave
conditions.)
8) In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the air conditioner.
9) Since drain flows out of the outdoor unit, do not place under the unit anything which must be kept away from moisture.
NOTE
Cannot be installed hanging from 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 snowfall areas, select an installation site where the snow will not affect the unit.

Be sure to add the proper amount of additional refrigerant.

Failure to do so may result in reduced perfomance.

The suggested shortest pipe length is 4.92ft (1.5m), in order to
avoid noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how
the unit is installed and the environment in which it is used.)
In sites with poor drainage, use
block bases for outdoor unit.
Adjust foot height until the unit
is leveled. Otherwise, water
leakage or pooling of water may
occur.

Install the unit high enough off the
ground to prevent burying in snow.
Wrap the insulation pipe with
the finishing tape from bottom
to top.
Set the piping length from
4.92ft (1.5m) to 65.6ft (20m).
Allow space for piping
and electrical servicing.
Where there is a danger of the unit
falling, use foot bolts, or wires.
