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 See
28] 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.
