Manufacturer reserves the right to change at any time for specifications or designs without notice and incurring obligations.
2.3 Location Restrictions
Installation Clearance Requirement
Ensure the top discharge area is unrestricted for at
least 60 inches above the unit.
Do not locate outdoor unit near bedrooms since
normal operational sounds may be annoying.
Position unit to allow adequate space for
unobstructed airflow, wiring, refrigerant pipes,
and serviceability.
Allow a minimum of 20 in. clearance on one side of
access panel to a wall and a minimum of 24 in. on
the adjacent side of access panel. Maintain a
distance of 24 in. between units.
Position unit so water, snow, or ice from roof
or overhang cannot fall directly on unit.
Cold Climate Considerations
Precautions must 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 to flow out smoothly
prior to its refreezing.
A snow drift barrier should be installed around the
unit to prevent a build-up of snow on the unit sides.
