SELECTION OF INSTALLATION LOCA- 4.
TION
The refrigerant R410A itself is nontoxic, nonfl ammable
and is safe. If the refrigerant should leak however, its
concentration may exceed the allowable limit depending
on room size. Due to this it could be necessary to take
measures against leakage. Refer to the chapter “Caution
for refrigerant leaks”.
Select a proper location satisfying the following re- (1)
quirements with approval of the customer.
Suffi cient ventilation is secured. •
Adjacent houses are not annoyed. •
The foundation is strong enough to support the weight •
and withstand vibrations of the outdoor unit, and the
location is safe and allows horizontal installation.
The outdoor unit is exposed to rain as less as possible.
•
The space for installation and servicing is secured •
around the outdoor unit.
The indoor/outdoor piping length and wiring length are
•
within the allowable range.
When installing the outdoor unit in a location affected (2)
by strong wind, pay special attention to the following
items.
If strong wind whose velocity is 5 m/sec or more blows •
to the outdoor unit from the air outlet side, the air fl ow
rate of the outdoor unit is reduced, the outlet air is
sucked again (short-circuit), and the following effect may
be caused:
The capacity is deteriorated. •
The adhered frost increases during heating operation. •
The operation is stopped by pressure rise. •
If excessive strong wind continuously blows from the air •
outlet side of the outdoor unit, the fan may rotate in the
reverse direction at high speed, and lead to damage.
Install the outdoor unit in reference to the following
fi gures.
Position the air outlet side toward the building wall, •
fence or windbreak screen.

When installing the outdoor unit in a location with (3)
heavy snowfall, pay special attention to the following
items:
Prepare strong foundation. •
Attach the snow hood (optional accessory). •
Remove the suction grill on the rear so that snow will •
not be accumulated in the rear fi n.
When there is a possibility of short-circuit depending (4)
on the ambient situation, use the wind direction ad-
justing plate (optional accessory).
The inverter type air conditioner may cause noise in (5)
electric products.
When selecting an installation location, keep suffi -
cient distance from the air conditioner units and
wiring to radios, personal computers, stereos, etc. as
shown in the fi gure below.
In areas with weak electric waves, keep a distance of
120 in. or more from the indoor remote controller, etc.,
put the power cables and connection cables in con-
duit tubes, and ground the conduit tubes.
