Table 6. Cold Climate Considerations (Heat Pump Only)
Note: It is recommended that these precautions be taken for
units being installed in areas where snow accumulation and
prolonged below-freezing temperatures occur.
•
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 ice melted during defrost cycle
prior to its refreezing. Ensure that drain holes in unit base pan
are not obstructed, preventing drainage of defrost water.
•
If possible, avoid locations that are likely to accumulate 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.
Coastal Considerations
If installed within one mile of salt water, including seacoasts and inland waterways, models without factory supplied Seacoast Salt Shields
require the addition of BAYSEAC001 (Seacoast Kit) at installation time.
N N o o t t e e : : It may also be necessary to install a BAYECCK001
(Extreme Conditions Kit) on units that are located
in very close proximity to saltwater
environments.
