It is recommended to provide at least 150 mm of free space below
the unit (300 mm for heavy snowfall areas). Additionally, make sure
the unit is positioned at least 100 mm above the maximum expected
level of snow. If necessary, construct a pedestal. See
In heavy snowfall areas it is very important to select an installation
site where the snow will NOT affect the unit. If lateral snowfall is
possible, make sure that the heat exchanger coil is NOT affected by
the snow. If necessary, install a snow cover or shed and a pedestal.
