It is recommended to provide at least 150 mm of free space below the unit

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.
By default, the outdoor unit heat pump can operate until –7°C. Depending on the
