UNIT LOCATION
Consider the affect of outdoor fan noise on conditioned space and any
adjacent occupied space. It is recommended that the unit be placed so
that condenser air discharge does not blow toward windows less than 25
feet away. Consideration should also be given to shade and unit appear-
ance.
Heat pumps require special location consideration in areas of heavy snow
accumulation and/or areas with prolonged continuous subfreezing tem-
peratures. Heat pump unit bases have holes under the outdoor coil to
permit drainage of defrost water accumulation. The unit must be situ-
ated to permit free unobstructed drainage of the defrost water and ice.
A minimum 2" clearance under the outdoor coil is required in the milder
climates.
GROUND LEVEL PRE-INSTALLATION DETAILS
The unit should be set on a solid, level foundation - preferably a concrete
slab at least 4 inches thick. The slab should be above ground level and
surrounded by a graveled area for good drainage. Any slab used as a
unit’s foundation should not adjoin the building as it is possible that
sound and vibration may be transmitted to the structure.
Ground Level Installation
ROOF TOP PRE-INSTALLATION DETAILS
Ensure that the roof is weather tight and allows proper drainage
of condensation. Use steel or treated wood beams as unit sup-
port for load distribution.
NOTE: To ensure proper condensate drainage, unit must be in-
stalled in a level position.
• To avoid possible property damage or personal injury, the
roof must have sufficient structural strength to carry the
weight of the unit(s) and snow or water loads as required
by local codes. Consult a structural engineer to determine
the weight capabilities of the roof.
• The unit may be installed directly on wood floors or on
Class A, Class B, or Class C roof covering material.
• To avoid possible personal injury, a safe, flat surface for
service personnel should be provided.

ROOF CURB INSTALLATIONS ONLY
NOTE: Sufficient structural support must be determined prior to
locating and mounting the curb and package unit.
Curb insulation, cant strips, flashing and general roofing material
are furnished by the contractor.
Curbing must be installed in compliance with the National Roof-
ing Contractors Association Manual. Construct duct work using cur-
rent industry guidelines. The duct work must be placed into the roof curb
before mounting the package unit.
