Additional installation site requirements
of the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.
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.
