CODES AND REGULATIONS
General
The GPC & GPH series air conditioners and heat pumps
are designed for OUTDOOR USE ONLY. This series is avail-
able in cooling Capacities of 2, 2 ½, 3, 3 ½, 4 and 5 nominal
tons of cooling. Optional field installed heat kits are avail-
able in 5,8,10,15 and 20 KW. The units can be easily in-
stalled 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 applica-
tions. The GPC & GPH 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 ARI certi-
fied.
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 (EPA) HAS ISSUED VARIOUS
REGULATIONS REGARDING THE INTRODUCTION AND
DISPOSAL OF REFRIGERANTS IN THIS UNIT. FAILURE TO
FOLLOW THESE REGULATIONS MAY HARM THE
ENVIRONMENT AND CAN LEAD TO THE IMPOSITION OF
SUBSTANTIAL FINES. BECAUSE REGULATIONS MAY VARY
DUE TO PASSAGE OF NEW LAWS, WE SUGGEST A
CERTIFIED TECHNICIAN PERFORM ANY WORK DONE ON
THIS UNIT. SHOULD YOU HAVE ANY QUESTIONS PLEASE
CONTACT THE LOCAL OFFICE OF THE EPA.
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
General
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.
INSTALLATION
Pre-Installation Checkpoints
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
Clearance
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 or left sides 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. Allow 18" minimum for service access to the
