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 manu-
factured or modular homes with existing high-static duct work.
The units can also be easily converted to accommodate a ple-
num for normal or low-static applications. The GPC/GPH M-se-
ries 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 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 effi-
ciency ratings of these units are a product of thermal efficiency
determined under continuous operating conditions independent
of any installed system.

NATIONAL
CODES
This product is designed and manufactured to permit installation
in accordance with National Codes. It is the iostaller's responsi-
bilityto 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 (con-
sisting of a compressor, condenser coil, evaporator coil with flow-
rafor), an indoor blower, a condenser fan and all necessary inter-
nal 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 perfor-
mance tested. Refrigerant amount and type are indicated on rat-
ing 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
Brain 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 un-
obstructed condenser air inlet and discharge. Additionally, the
unit must be situated to permit access for service and installa-
tion. 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 cor-
ners provide a minimum 10" clearance on all air inlet sides. 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 win-
dows 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 sub-
freezing 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
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.
