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 fi gures below.
(Take care so that hands and objects do not touch the fi n on
the rear.)

If the suction hole area on the side of the casing
is held, the casing may be deformed. Make sure
to hold the corner.
Make sure to use accessories and specifi ed specifi cation
parts in the installation work.
4. 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".
(1) 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.
• 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 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
wind direction.

(3) When installing the outdoor unit in a location with
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.
(4) When there is a possibility of short-circuit depending
on the ambient situation, use the wind direction ad-
justing plate (optional accessory).
(5) The inverter type air conditioner may cause noise in
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.
