5-6. Measures against strong winds
Precautions for installing the unit in a place exposed to strong winds
This unit is standard-equipped with air deflector grills to protect itself against headwinds. However, if the unit is installed on
a roof or in an isolated place with no surrounding buildings, take appropriate measures so that the air discharge outlet on the
unit is not exposed to winds. If strong winds blow directly into the air discharge outlet, the unit cannot hold sufficient air and
will fail to operate properly.
If powder snow is expected to blow on the front side of the unit in winter, install a wall in front of the unit to keep the snow
from entering the unit. When powder snow blows directly into the air discharge outlet while the unit is stopped, the snow en-
tering the unit may cause operation problems.
[1] Installing the unit near a wall
Install the unit so that the air discharge outlet will face the
wall. Leave 500 mm between the unit and the wall.
If the wall height exceeds the unit height, refer to the in-
stallation examples in the previous section to determine
the amount of the space between the unit and the wall.
[2] Installing the unit in a place exposed to winds
Install the unit so that the air discharge outlet is perpen-
dicular to the direction of the winds.
If powder snow is expected to blow directly into the air dis-
charge outlet, install a wall in front of the unit to keep the
snow from entering the unit. Leave 500 mm between the
unit and the wall.
• Air deflector grills can direct the air upward (factory set-
ting), to the left, or to the right. Select the air flow direction
to suit the local installation conditions. (Refer to the fig-
ures on the right.)
5-7. Measures against snow
5-7-1. Installing the unit in a winter snow area
Install the unit on a raised base (locally procured).
If the unit is not installed on a raised base and not operat-
ed for a long time, moisture will accumulate inside the
unit, forming rust.
