CODES AND REGULATIONS
The *PH/C M-series heat pumps are designed for OUTDOOR
USE ONLY. *PH M-Series is available in cooling capacities of
2, 2.5 3, 4 and 5 nominal tons of cooling. The GPC is only
available in 2 thru 4 ton. Optional field installed heat kits are
available in 5,8,10,15 and 20 kW. The units can be easily
installed in manufactured or modular homes with existing
high-static duct work. The units can also be easily converted
to accommodate a plenum for normal or low-static
applications. The *PH/C M-series are self contained packaged
units so the only connections needed for installation are the
supply and return ducts, the line and low voltage wiring and
drain connection. Rated performance is achieved after 72
hours of operation. The units are ETL listed and AHRI certified.
The information on the rating plate is in compliance with the
FTC & DOE rating for single phase units.
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 factoryevacuated, charged and performance tested. Refrigerant
amount and type are indicated on rating plate.
PRE-INSTALLATION 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 four sides of a home,
manufactured or modular, to minimize noise
CLEARANCES AND A CCESSIBILITY
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 three 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” from wall (4” minimum) with the connection side
facing the wall. This “close to the wall” application minimizes
exposed wiring.
Close to the wall application assures free, unobstructed air
to the other two sides. In more confined application spaces,
such as corners provide a minimum 12” clearance on all air
inlet sides. Allow 36” 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 48”
clearance and provisions made to deflect the warm discharge
air out from the overhang.
EPA REGULATIONS
IMPORTANT: THE UNITED STATES ENVIRONMENTAL PROTECTION
AGENCY (EPA) HAS ISSUED VARIOUS REGULATIONS REGARDING THE
INTRODUCTION
AND DISPOSAL OF REFRIGERANTS IN THIS UNIT.

NATIONAL C ODES
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.
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 condenser air discharge does not
blow toward windows less than 25 feet 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" clearance under
the outdoor coil is required in the milder climates.
GROUND L EVEL P RE-INSTALLATION D ETAILS
The unit should be set on a solid, level foundation - preferably
a concrete slab at least 4 inches 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.

Ground Level Installation
ROOF TOP P RE-INSTALLATION DETAILS
Ensure that the roof is weather tight and allows proper
drainage of condensation. Use steel or treated wood beams
as unit support for load distribution.
NOTE: To ensure proper condensate drainage, unit must be
installed in a level position.
• 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.
ROOF C URB INSTALLATIONS O NLY
NOTE: Sufficient structural support must be determined prior
to locating and mounting the curb and package unit.
Curb insulation, cant strips, flashing and general roofing
material are furnished by the contractor.
Curbing must be installed in compliance with the National
Roofing Contractors Association Manual. Construct duct work
using current industry guidelines. The duct work must be
placed into the roof curb before mounting the package unit.

CIRCULATING AIR AND FILTERS
A
IR FLOW C ONVERSION
Units can easily be converted from horizontal to down
discharge air flow 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 air
flow.
Horizontal Air Flow
Single phase models are shipped without horizontal duct
covers. If needed, these kits may be ordered through
Goodman’s Service Parts department.
Return
Supply
Remove these panels
for downflow duct
applications
Duct Cover Installation
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: Single phase models require installation of horizontal
duct kit #20464501PDGK (medium chassis) and
#20464502PDGK (large chassis).
DUCT WORK
Duct systems and register sizes must be properly designed
for the C.F.M. and external static pressure rating of the unit.
Duct work should be designed in accordance with the
recommended methods of Air Conditioning Contractors of
America Manual D (Residential) or Manual Q (Commercial).
All duct work 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 No. 90A and 90B.
The supply duct from the unit through a wall may be installed
without clearance. However, minimum unit clearances as
shown in the Appendix 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 duct work should be
attached to the roof curb prior to installing the unit. Duct work
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.
FILTERS
Filters are not provided with unit and must be supplied and
externally installed in the return duct system by the installer. A
field-installed filter grille is recommended for easy and
convenient access to the filters for periodic inspection and
cleaning. When installing filters, ensure the air flow arrows
on the filter are pointing toward the circulator blower.
