National Codes
This product is designed and manufactured to permit installation
in accordance with National Codes. It is the installer’s
responsibility to install the product in accordance with National
Codes and/or prevailing local codes and regulations.
MAJOR COMPONENTS
The unit includes a hermetically sealed refrigerating system
(consisting of a compressor, condenser coil, evaporator coil with
flowrator), an indoor blower, a condenser fan and all necessary
internal electrical wiring. The heat pump also includes a reversing
valve, solenoid, defrost thermostat and control and loss of charge
protection. The system is factory-evacuated, charged and
performance tested. Refrigerant amount and type are indicated
on rating plate.
PREINSTALLATION CHECKS
Before attempting any installation, the following points should be
considered:
■ Structural strength of supporting members
■ Clearances and provision for servicing
■ Power supply and wiring
■ Air duct connections
■ Drain facilities and connections
■ Location may be on any 4 sides of a home, manufactured or
modular, to minimize noise.
Clearances and Accessibility
The unit is designed to be located outside the building with
unobstructed condenser air inlet and discharge. Additionally, the
unit must be situated to permit access for service and
installation. Condenser air enters from 3 sides. Air discharges
upward from the top of the unit. Refrigerant gauge connections
are made on the right side of the unit as you face the compressor
compartment. Electrical connections can be made either on the
right, bottom or duct panel side of the unit. The best and most
common application is for the unit to be located 10" (25.4 cm)
from the wall (4" [10.2 cm]) minimum) with the connection side
facing the wall. Close to the wall application minimizes exposed
wiring.
3
Close to the wall application assures free, unobstructed air to the
other 2 sides. In more confined application spaces, such as
corners, provide a minimum 10" (25.4 cm) clearance on all air
inlet sides. Allow 18" (45.7 cm) minimum for service access to the
compressor compartment and controls. The top of the unit
should be completely unobstructed. If units are to be located
under an overhang, there should be a minimum of 36" (91.4 cm)
clearance and provisions made to deflect the warm discharge air
out from the overhang.
■ To avoid possible property damage or personal injury, the
roof must have sufficient structural strength to carry the
weight of the unit(s) and snow or water loads as required by
local codes. Consult a structural engineer to determine the
weight capabilities of the roof.
■ The unit may be installed directly on wood floors or on Class
A, Class B or Class C roof covering material.
■ To avoid possible personal injury, a safe, flat surface for
service personnel should be provided.
Unit Location
Consider the affect of outdoor fan noise on conditioned space
and any adjacent occupied space. It is recommended that the
unit be placed so that the condenser air discharge does not blow
toward windows less than 25 ft (7.6 m) away. Consideration
should also be given to shade and unit appearance.
Heat pumps require special location consideration in areas of
heavy snow accumulation and/or areas with prolonged
continuous subfreezing temperatures. Heat pump unit bases
have holes under the outdoor coil to permit drainage of defrost
water accumulation. The unit must be situated to permit free
unobstructed drainage of the defrost water and ice. A minimum
2" (5 cm) clearance under the outdoor coil is required in the
milder climates.
Ground Level Preinstallation Details
The unit should be set on a solid, level foundation—preferably a
concrete slab at least 4" (10.2 cm) thick. The slab should be
above ground level and surrounded by a graveled area for good
drainage. Any slab used as a unit’s foundation should not adjoin
the building as it is possible that sound and vibration may be
transmitted to the structure.

CIRCULATING AIR AND FILTERS
Airflow Conversion
Units can easily be converted from horizontal to down-discharge
airflow delivery. In down-discharge or high-static installations, the
installer should measure the total external static and review the
blower performance charts before performing the installation. In
some installations, it will be necessary to change the blower
speed to provide proper airflow.
Down-Discharge Applications
Cut insulation around bottom openings and remove panels from
the bottom of the unit, saving the screws holding the panels in
place.
NOTE: Down-discharge models require installation of horizontal
duct kit Number 20464501PDGK (medium chassis) and Number
20464502PDGK (large chassis).
Ductwork
Duct systems and register sizes must be properly designed for
the C.F.M. and external static pressure rating of the unit.
Ductwork should be designed in accordance with the
recommended methods of Air Conditioning Contractors of
America Manual D (Residential) or Manual Q (Commercial).
All ductwork exposed to the outdoors must include a
weatherproof barrier and adequate insulation. A duct system
should be installed in accordance with Standards of the National
Board of Fire Underwriters for the Installation of Air Conditioning,
Warm Air Heating and Ventilating Systems. Pamphlets Number
90A and 90B.
The supply duct from the unit through a wall may be installed
without clearance. However, minimum unit clearances must be
maintained. The supply duct should be provided with an access
panel large enough to inspect the air chamber downstream of the
heat exchanger. A cover should be tightly attached to prevent air
leaks.
For duct flange dimensions on the unit, refer to the Unit
Dimension illustration in the appendix.
For down-discharge applications, the ductwork should be
attached to the roof curb prior to installing the unit. Ductwork
dimensions are shown in the roof curb installation manual.
If desired, supply and return duct connections to the unit may be
made with flexible connections to reduce possible unit operating
sound transmission.
