
Units should be elevated 3-12 inches above the pad or rooftop,
depending on local weather. This additional height will allow drainage
of snow and will permit condensate water to drain when the unit
is in defrost mode. Ensure that drain holes in unit base pan are
unobstructed, preventing drainage of defrost water (See Fig.9).

If possible, avoid locations that are prone to snow drifts. If not possible,
a snow drift barrier should be installed around the unit to prevent a
build-up of snow on the sides of the unit.
E nsure that Condensate Drain side is pitched lower than the
opposite side.
