BEFORE INSTALLATION
<Bringing-in>
Bring in the outdoor unit slowly by holding the lugs provided on the left
and right sides as shown in the figures below.
(Take care so that hands and objects do not touch the fin on the rear.)
Make sure to use accessories and specified specification parts in the
installation work.

SELECTION OF INSTALLATION
LOCATION
The refrigerant R410A itself is nontoxic, nonflammable and 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”.
(1) Select a proper location satisfying the following requirements
with approval of the customer.
•
Sufficient ventilation is secured.
•
Adjacent houses are not annoyed.
•
The foundation is strong enough to support the weight and with-
stand 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 out-
door unit.
•
The indoor/outdoor piping length and wiring length are within the
allowable range.
(2) 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 out-
door unit from the air outlet side, the air flow 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 refer-
ence to the following figures.
•
Position the air outlet side toward the building wall, fence or
windbreak screen.
•
Let the air outlet direction face be at right angles to the wind
direction.
(3) When installing the outdoor unit in a location with heavy snow-
fall, 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 accu-
mulated in the rear fin.
(4) When there is a possibility of short-circuit depending on the
ambient situation, use the wind direction adjusting plate
(optional accessory).
