CODES AND REGULATIONS
SAFETY INSTRUCTIONS
The following symbols and labels are used throughout this manual
to indicate immediate or potential safety hazards. It is the owner’s
and installer’s responsibility to read and comply with all safety
information and instructions accompanying these symbols. Failure to heed safety information increases the risk of personal injury,
property damage, and/or product damage.
WARNING
DO NOT CONNECT TO OR USE ANY DEVICE THAT IS NO T DESIGN-CERTIFIED
BY
GOODMAN FOR USE WITH THIS UNIT. SERIOUS PROPERTY DAMAGE,
PERSONAL INJURY, REDUCED UNIT PERFORMANCE AND/
CONDITIONS MAY RESULT FROM THE USE OF SUCH NON-APPROVED DEVICES.
OR HAZARDOUS
The GPC/GPH M-series air conditioners and heat pumps are designed for OUTDOOR USE ONLY. GPH M-Series is available in
cooling capacities of 2, 2-1/2, 3, 3-1/2, 4 and 5 nominal tons of
cooling. GPC M-Series is available in cooling capacities of 3, 4
and 5 nominal tons of cooling. Optional field installed heat kits are
available in 5,8,10,15 and 20 kW. 3 phase heat kits are available
only in 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 GPC/GPH 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. 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. The three phase units in
this series are not covered under the DOE certified program. The
efficiency ratings of these units are a product of thermal efficiency determined under continuous operating conditions independent of any installed system.
EPA REGULATIONS
IMPORTANT: THE UNITED STATES ENVIRONMENTAL PROTECTION
AGENCY (EP A) HAS ISSUED VARIOUS REGULATIONS REGARDING
INTRODUCTION AND DISPOSAL OF REFRIGERANTS IN THIS UNIT.
THE
FAILURE TO FOLLOW THESE REGULATIONS MAY HARM THE
ENVIRONMENT
. BECAUSE REGULATIONS MAY VARY DUE TO PASSAGE OF
FINES
LAWS, WE SUGGEST A CERTIFIED TECHNICIAN PERFORM ANY
NEW
WORK
PLEASE
AND CAN LEAD TO THE IMPOSITION OF SUBSTANTIAL
DONE ON THIS UNIT. SHOULD YOU HAVE ANY QUESTIONS
CONTACT THE LOCAL OFFICE OF THE EPA.
Allow 18” 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” clearance and provisions made to
deflect the warm discharge air out from the overhang.
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.
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.
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 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 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 10” clearance on all air inlet sides.
GROUND LEVEL PRE-INSTALLATION DETAILS
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 PRE-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.

IMPORTANT: If using bottom discharge with roof curb, duct work
should be attached to the curb prior to installing the unit.
Lower unit carefully onto roof mounting curb. While rigging unit,
center of gravity will cause condenser end to be lower than supply
air end.
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
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 air flow.
Horizontal Air Flow (Applies to 3 phase models)
Single phase models are shipped without horizontal duct
covers. If needed, these kits may be ordered through
Goodman’s Service Parts department.
