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 construct a lateral
canopy).
Construct a large canopy.
Construct a pedestal.
Install the unit high enough off the ground
to prevent burying in snow.
