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. 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.
