Wind
If the unit is being installed in windy areas, ensure
that the warm outlet air is discharged in the pre-
vailing wind direction. If this is not the possible, it
may be necessary to install a windbreak (to be pro-
vided by the customer). Ensure that the windbreak
does not adversely affect the air intake to the unit.
An additional stabilization is recommended. This
can, for example, be realized with ropes or other
structures.

Snow
The unit should be wall-mounted in areas of heavy
snowfall. Installation should be at least 20cm
above the expected level of snow to prevent snow
from entering the outdoor unit. An optional wall
bracket is available as an accessory.
