The installation of the heat pump or condensing unit, wiring,
warm air ducts, venting, etc., must conform to the requirements
of the National Fire Protection Association; the National Electrical
Code, ANSI/NFPA No. 70 (latest edition) in the United States, and
any state laws, local ordinances (including plumbing or

This heat pump or condensing unit is designed to be located
outdoors with sufficient clearance for free entrance to the
inlet and discharge air openings. The location must also allow
for adequate service access. See "Minimum Clearances."
Where possible, select a location for the heat pump or
condensing unit which is shaded from the direct rays of the
sun most of the time. North or east locations are usually most
desirable. Position the heat pump or condensing unit to avoid
direct contact with water, snow or ice from a roofline
The heat pump or condensing unit must be installed on a
solid, level mounting pad that will not settle or shift. Isolate
the pad from the building structure to avoid possible
transmission of sound or vibration from the heat pump or
condensing unit into the conditioned space.
The heat pump or condensing unit foundation should be
raised to a minimum of 3" above finish grade. In areas which
have prolonged periods of temperature below freezing and
snowfall, the heat pump or condensing unit should be
elevated above the average snow line. If the heat pump or
condensing unit is to be installed on a flat roof, it should be
on a platform or other support which will raise the base a
minimum of 8" above the surface of the flat roof.
Avoid placing a heat pump or condensing unit near areas
such as sleeping quarters or study rooms. Normal operating
sound levels may be louder than desired if the heat pump or
condensing unit is placed near certain rooms.

The heat pump or condensing 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 protected
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.
