HEAT PUMP INSTALLATION
General Information
Split system heat pumps are designed only for outdoor rooftop
or ground level installations. 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. 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.
Refer to the Quick Reference Data sheet for additional
electrical, charging and unit information.
Before You Install the Heat Pump
√
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. The system must be wired
and provided with circuit protection in accordance with
local building codes. If there is any question concerning
the power supply, contact the local power company.
√
The indoor section (air handler, furnace, etc) should be
installed before routing the refrigerant tubing. Refer to
the indoor unit's installation instructions for installation
details.
√
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.
• Overhead obstructions, poorly ventilated areas, and areas
subject to accumulation of debris should be avoided. See
Figure 1 .
• Sufficient clearance for unobstructed airflow through the
outdoor coil must be maintained in order to achieve rated
performance. See Figure 1 for minimum clearances to
obstructions.
• Consideration should be given to availability of electric
power, service access, noise, and shade.
Packaging Removal
To prevent damage to the tubing onnections, carefully remove
the carton and user’s manual from the equipment. Discard
the shipping carton.
Ground Level
Ground level installations must be located according to local
building codes or ordinances and these requirements:
• Clearances must be in accordance with those shown in
Figure 1 .
• A suitable mounting pad must be provided and be separate
from the building foundation. The pad must be level and
strong enough to support the unit’s weight. The slab height
must be a minimum of 2” (5 cm) above grade and with
adequate drainage. See Figure 1 .
Rooftop
• The method of mounting should be designed so that it
does not overload roof structures or transmit noise to
the interior of the structure. The roof must be structurally
capable of handling the weight of the unit.
• Full perimeter support is required under the unit. Support
must be made of weather resistant materials and installed
prior to unit installation.
• The support must be built to raise the unit 6" above the
roof.
