Installation & Operation Manual

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.
