BEFORE INSTALLATION

3. 

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.

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.

Suction 
grille

(Secure the space for installation and servicing.)

Let the air outlet direction face be at right angles to the 

 

wind direction.

Strong wind

Strong wind

Air outlet

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.
