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.
• The length of the supply and return ducts should be kept to
a minimum with no sharp radius bends.
• 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.
Minimum Clearances
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). However, 36” inches
from blower access panel, electrical panel, and compressor
panel is highly recommended for servicing and maintenance.
For minimum clearances to obstructions, see
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.
Service Access Clearance:
Blower and control access panels ............................. 24”
Compressor compartment access panel ................... 24”
Clearance from top of unit ........................................ 72”
Clearance around condenser coil area to
Wall or shrubs (excludes duct panel side) ................. 12”
Clearances to Combustibles:
Combustible base - wood or Class A, B, or C
roof covering material ................................................. 0”
Supply & return air ducts ............................................ 0”
Duct connection side .................................................. 0”
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
This packaged heat pump is designed only for outdoor ground
level installations and can be readily connected to the high static
duct system of a home. This unit is completely assembled, wired,
and run tested at the factory. The only connections needed
for installation are the supply and return ducts, line voltage,
thermostat wiring and the condensate drain.
This unit has been tested for capacity and efficiency in accordance
with AHRI standards and will provide many years of safe and
dependable comfort, providing it is properly installed and
maintained. Use of components other than those specified may
invalidate AHRI certification, Code Agency Listing, and limited
warranty on the heat pump.
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. 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
