In any case, provide at least 300 mm of free space below the unit. Additionally,
make sure the unit is positioned at least 100 mm above the maximum expected
level of snow. See "7.3Mounting the outdoor unit"[476] for more details.
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.
