2 When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:
-
Deterioration of the operational capacity.
- Frequent frost acceleration in heating operation.
- Disruption of operation due to rise of high pressure.
- When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.
■
Turn the air outlet side toward the building's wall, fence or
screen.
■
Set the outlet side at a right angle to the direction of the wind.
3 Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
4 If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be maximum 150 mm).
5 If you install the unit on a frame, please install a waterproof plate
within 150 mm of the underside of the unit in order to prevent the
invasion of water from the lower direction.
6 When installing the unit in a place frequently exposed to snow,
pay special attention to the following:
- Elevate the foundation as high as possible.
- Remove the rear suction grille to prevent snow from
accumulating on the rear fins.
7 If you install the unit on a building frame, please install a
waterproof plate (within 150 mm of the underside of the unit) in
order to avoid the drainwater dripping. (See figure).
