SELECTION OF INSTALLATION LOCA-
TION
The refrigerant R410A itself is nontoxic, nonfl ammable
and safe. If the refrigerant should leak however, its con-
centration may exceed the allowable limit depending on
room size. Due to this it could be necessary to take mea-
sures against leakage. Refer to the chapter "Caution for
refrigerant leaks".

Select a proper location satisfying the following re-
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.

When installing the outdoor unit in a location affected
by strong wind, pay special attention to the following
items.
•
If strong wind whose velocity is 11 mph 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.
(Secure the space for installation and servicing.)
•
Let the air outlet direction face be at right angles to the
