area where they will be shaded from the afternoon sun, when
the heat load is greatest.
• Consideration should also be given to availability of electric
power, service access, noise, and shade.
• Overhead obstructions, poorly ventilated areas, and areas
subject to accumulation of debris should be avoided. The
hot condenser air must be discharged up and away from the
home, and if possible, in a direction with the prevailing wind.
Do not place the unit in a confined space. See
for unit dimensions.
• Sufficient clearance for unobstructed airflow through the
outdoor coil must be maintained in order to achieve rated
performance (except on supply & return duct (rear) side). For
minimum clearances to obstructions, see
.
Minimum Clearances
Minimum clearances MUST be maintained from adjacent
structures to provide room for proper servicing and air circulation.
DO NOT install unit in a confined or recessed area that will allow
discharge air from the unit to re-circulate into the condenser air
inlet, through the coil. See
.

REQUIREMENTS & CODES
• All electrical wiring must be completed in accordance with
local, state & national codes and regulations and with the
National Electric Code (ANSI/NFPA 70) or in Canada the
Canadian Electric Code Part 1 CSA C.22.1.
• The installer must comply with all local codes and regulations
which govern the installation of this type of equipment.
Local codes and regulations take precedence over any
recommendations contained in these instructions. Consult
local building codes and the National Electrical Code (ANSI
CI) for special installation requirements.
• Air Ducts must be installed in accordance with the standards
of the National Fire Protection Association “Standards for
Installation of Air Conditioning and Ventilation Systems” (NFPA
90A), “Standard for Installation of Residence Type Warm Air
Heating and Air Conditioning Systems” (NFPA 90B), these
instructions, and all applicable local codes.
, and the rating plate for the
proper circulating air flow and temperature rise. It is important
that the duct system be designed to provide the correct flow
rates and external pressure rise. An improperly designed
duct system can result in nuisance shutdowns, and comfort
or noise issues.
• This unit is designed for outdoor installations only and should
be positioned as described in Locating the Heat Pump.
GENERAL INFORMATION
Single packaged heat pumps are ready for easy and immediate
installation and can be readily connected into the high static duct
system of a home. This unit is completely assembled, wired,
and run tested at the factory.
This heat pump is designed
for outdoor installation only.
The only connections needed
for installation are the supply and return ducts, line voltage,
thermostat wiring and the condensate drain. Use of components
other than those specified may invalidate AHRI Certification,
Code Agency Listing, and limited warranty on the air conditioner.
Before You Install this Unit
√
The cooling load of the area to be conditioned must be
calculated and a system of the proper capacity selected. It is
recommended that the area to be conditioned be completely
insulated and vapor sealed.
√
Check the electrical supply and verify the power supply is
adequate for unit operation. If there is any question concerning
the power supply, contact the local power company.
√
All units are securely packed at the time of shipment and
upon arrival should be carefully inspected for damage prior
to installing the equipment at the job site. Verify coil fins are
straight. If necessary, comb fins to remove flattened or bent
fins. Claims for damage should be filed immediately with the
carrier.
√
Please consult your dealer for maintenance information
and availability of maintenance contracts. Please read all
instructions before installing the unit.
Locating the Heat Pump
• Survey the job site to determine the best location for mounting
the outdoor unit. Select a solid, level position, preferably on a
concrete slab, slightly above the grade level, and parallel to
the home. Unit can also be mounted on a roof curb or a metal
stand. High wind kits are available to prevent unit movement
in adverse conditions. If possible, select a site for the unit that
is as close as possible to the proposed return grille location.
DO NOT PLACE UNIT UNDER THE HOME.
• The unit should be located with consideration of minimizing
the length of the supply and return ducts with no sharp radius
bends. If practical, place the heat pump and its ducts in an
