Location Requirements

Consider the effect of the outdoor fan noise on conditioned
space and any adjacent occupied space. It is recommended that
the unit be placed so that the condenser air discharge does not
blow toward windows less than 25 ft (7.6 m) away.

Heat pumps require special location consideration in areas of
heavy snow accumulation and/or areas with prolonged
continuous subfreezing temperatures. Heat pump unit bases
have holes under the outdoor coil to permit drainage of defrost
water accumulation. The unit must be situated to allow free
unobstructed drainage of the defrost water and ice. A minimum
2" (5.1 cm) clearance under the outdoor coil is required in milder
climates.

Ground Level Preinstallation Details

The unit should be set on a solid, level foundation, preferably a
concrete slab at least 4" (10.2 cm) 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, since it is possible that sound and vibration may be
transmitted to the structure.

Rooftop Preinstallation Details

Check that the roof is weathertight and allows proper drainage of
condensation. Use steel or treated wood beams as unit support
for load distribution.

NOTE: To ensure proper condensate drainage, the unit must be
installed 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.

Rooftop Installation

■ The ductwork must be placed into the roof curb before

mounting the package unit.

Roof Curb G 2009 ENV3

Roof Curb Installations Only

NOTES:

■ 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

Roofing Contractors Association Manual.

■ Construct ductwork using current industry guidelines.

Minimum Clearances

The unit is designed to be located outside the building with an
unobstructed condenser air inlet and discharge. Additionally, the
unit must be situated to permit access for service and
installation.

Condenser air enters from 3 sides. Air discharges upward from
the top of the unit. Refrigerant gauge connections are made on
the right-hand side of the unit as you face the compressor
compartment.

Electrical connections can be made on the right-hand side of the
unit. The best and most common application is for the unit to be
located 10" (25.4 cm) from the wall (4" [10.2 cm] minimum) with
the connection side facing the wall. This close-to-the-wall
application minimizes exposed wiring. Close-to-the-wall
application assures free, unobstructed air to the other 2 sides. In
more confined application spaces, such as corners, provide a
minimum 10" (25.4 cm) clearance on all air inlet sides.

Allow 18" (45.7 cm) minimum for service access to the
compressor compartment and controls. The top of the unit
should be completely unobstructed.

If the unit is to be located under an overhang, there should be a
minimum of 36" (91.4 cm) clearance and provisions made to
deflect the warm discharge air out from under the overhang.

Ductwork Requirements

■ Install all conditioned air plenums, ducts and air filters in

accordance with NFPA 90B Standard for the Installation of
Warm Air Heating and Air-Conditioning Systems (latest
edition).

■ The heat pump or air conditioning unit is provided with

flanges for the connection of the plenum and ducts.

■ All air filters must be listed as Class 2 air filters.

■ All ductwork must be made of materials and insulated to

meet local, state and national codes. Ductwork installed
outdoors must be sealed, weatherproof and sheltered against
physical damage. Caulking, flashing or other means of
adequately providing a permanent weather seal should be
used where duct penetrates a building or structure opening.

Airflow Conversion

Units can easily be converted from horizontal to downflow airflow
delivery. In downflow or high static installations, the installer
should measure the total external static and review the blower
performance charts before performing the installation. In some
installations it will be necessary to change the blower speed to
provide proper airflow.

Horizontal Airflow

Single phase models are shipped without horizontal duct covers.
If needed, these kits may be ordered through your local supplier.
