These instructions are intended as a general guide only for use by
qualified persons and do not supersede any national or local
codes in any way. Compliance with all local, state, or national
codes pertaining to this type of equipment should be determined
prior to installation.
Read this entire instruction manual, as well as the instructions
supplied in separate equipment, before starting the installation.
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
wastewater codes). Local authorities having jurisdiction should
be consulted before installation is made. Such applicable
regulations or requirements take precedence over the general
instructions in this manual.

Tools and Parts

Gather the required tools before starting installation. Read and
follow the instructions provided with any tools listed here.
Tools needed
⁵⁄₁₆" nut driver
Tape measure
Screwdriver
Parts needed
Check local codes and existing electrical supply. Read "Electrical
Requirements" and "Ductwork Requirements" before purchasing
parts.

Location Requirements

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
overhead.
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.

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 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.
