This single package heat pump has been designed and
tested for capacity and efficiency in accordance with A.R.I.
Standards. This unit will provide many years of safe and
dependable comfort, providing it is properly installed and
maintained. This heat pump is designed only for outdoor
installations. With regular maintenance, this unit will
operate satisfactorily year after year. Abuse, improper
use, and/or improper maintenance can shorten the life
of the appliance and create unsafe hazards.
To achieve optimum performance and minimize equipment
failure, it is recommended that periodic maintenance be
performed on this unit. The ability to properly perform
maintenance on this equipment requires certain
mechanical skills and tools.

Pre-installation check

√ 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 (apparent or
concealed) 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.
• Choose an appropriate location that minimizes the
length of the supply and return air ducts.
• Overhead obstructions, poorly ventilated areas, and
areas subject to accumulation of debris should be
avoided.
• Sufficient clearance for unobstructed airflow through the
outdoor coil must be maintained in order to achieve rated
performance. See Figure 2 for minimum clearances to
obstructions.
• Consideration should also be given to availability of
electric power, service access, noise, and shade.

Field connections for electrical Power Supply

• All wiring must comply with current provisions of the
National Electrical Code (ANSI/NFPA 70) and with
applicable local codes having jurisdiction.
• The minimum size of electrical conductors and circuit
protection must be in compliance with information listed
on the outdoor unit data label.
6
• Electrical power supplied to the unit must be adequate
for proper operation of the equipment. The system
must be wired and provided with circuit protection in
accordance with local building codes.

air Ducts

This unit is designed only for use with a supply and return
duct. Air ducts must be installed in accordance with the
standards of the National Fire Protection Association
Standard for Installation of Air Conditioning Systems
(NFPA 90A), Standard for Installation of Residence Type
Warm Air Heating and Air Conditioning Systems (NFPA
90B), and all applicable local codes. NFPA publications
are avaialable by writing to: National Fire Protection
Association, Batterymarch Park, Quincy, ME 02269 or
visit www.NFPA.org on the web.
• Design the duct work according to methods described
by the Air Conditioning Contractors of America (ACCA).
• The ducts must be properly sized not to exceed .2"
W.C. pressure drop at 400 scfm per nominal ton of
cooling capacity.
• Duct work should be attached directly to the unit flanges
for horizontal applications.
• If roof curb is installed, the ducts must be attached to
the curb hangers, not the unit.

Unconditioned Spaces

All duct work passing through unconditioned space must
be properly insulated to minimize duct losses and prevent
condensation. Use insulation with an outer vapor barrier.
Refer to local codes for insulation material requirements.

Acoustical Duct Work

Certain installations may require the use of acoustical
lining inside the supply duct work.
• Acoustical insulation must be in accordance with the
current revision of the Sheet Metal and Air Conditioning
Contractors National Association (SMACNA)
application standard for duct liners.
