2.4.1. Windy location installation
When installing the outdoor unit on a rooftop or other location unprotected from
the wind, situate the air outlet of the unit so that it is not directly exposed to strong
winds. Strong wind entering the air outlet may impede the normal airflow and a
malfunction may result.
The following shows three examples of precautions against strong winds.
1
Face the air outlet towards the nearest available wall about 50 cm away from the
wall. (Fig. 2-3)
2
Install an optional air guide if the unit is installed in a location where strong winds
from a typhoon, etc. may directly enter the air outlet. (Fig. 2-4)

3
Position the unit so that the air outlet blows perpendicularly to the seasonal wind
direction, if possible. (Fig. 2-5)

2.4.2. When installing a single outdoor unit (Refer to the last page)
Minimum dimensions are as follows, except for Max., meaning Maximum dimen-
sions, indicated.
Refer to the
Þ
gures for each case.

2
Obstacles at rear and above only (Fig. 2-7)
3
Obstacles at rear and sides only (Fig. 2-8)
4
Obstacles at front only (Fig. 2-9)
* When using the optional air outlet guides, the clearance is 500 mm or more.
5
Obstacles at front and rear only (Fig. 2-10)
* When using the optional air outlet guides, the clearance is 500 mm or more.
6
Obstacles at rear, sides, and above only (Fig. 2-11)
• Do not install the optional air outlet guides for upward air
ß
ow.
2.4.3. When installing multiple outdoor units (Refer to the last page)
Leave 10 mm space or more between the units.
1
Obstacles at rear only (Fig. 2-12)
2
Obstacles at rear and above only (Fig. 2-13)
• No more than 3 units must be installed side by side. In addition, leave space as shown.
• Do not install the optional air outlet guides for upward air
ß
ow.
3
Obstacles at front only (Fig. 2-14)
* When using the optional air outlet guides, the clearance is 1000 mm or more.
4
Obstacles at front and rear only (Fig. 2-15)
* When using the optional air outlet guides, the clearance is 1000 mm or more.
5
Single parallel unit arrangement (Fig. 2-16)
* When using the optional air outlet guides installed for upward air
ß
ow, the clearance is
1000 mm or more.
6
Multiple parallel unit arrangement (Fig. 2-17)
* When using the optional air outlet guides installed for upward air
ß
ow, the clearance is
1500 mm or more.
7
Stacked unit arrangement (Fig. 2-18)
• The units can be stacked up to 2 units high.
• No more than 2 stacked units must be installed side by side. In addition, leave space as
shown.
2.2. Choosing the outdoor unit installation location
• Avoid locations exposed to direct sunlight or other sources of heat.
• Select a location from which noise emitted by the unit will not inconvenience
neighbors.
• Select a location permitting easy wiring and pipe access to the power source
and indoor unit.
• Avoid locations where combustible gases may leak, be produced,
ß
ow, or accu-
mulate.
• Note that water may drain from the unit during operation.
• Select a level location that can bear the weight and vibration of the unit.
• Avoid locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation loca-
tion or installing a hood on the air intake must be taken to prevent the snow from
blocking the air intake or blowing directly against it. This can reduce the air
ß
ow
and a malfunction may result.
• Avoid locations exposed to oil, steam, or sulfuric gas.
• Use the transportation handles of the outdoor unit to transport the unit. If the unit
is carried from the bottom, hands or
Þ
ngers may be pinched.
