legislation.
14.1.2 Additional installation site requirements
of the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.

a Snow cover or shed
b Pedestal (minimum height=150 mm)
c Prevailing wind direction
d Air outlet
Snow might build up and freeze between the heat exchanger and
the casing of the unit. This might decrease the operating efficiency.
For instructions on how to prevent this (after mounting of the unit),
see "14.3.3 To provide drainage" [ 4 27].
NOTICE
When operating the unit in heating in a low outdoor
ambient temperature with high humidity conditions, make
sure to take precautions to keep the drain holes of the unit
free by using proper equipment.
