WARNING
WARNING
SYSTEM CONTAMINANTS, IMPROPER SERVICE PROCEDURE AND/OR PHYSICAL
ABUSE AFFECTING HERMETIC COMPRESSOR ELE CTRICAL TERMINALS MAY
CAUSE DANGEROUS SYSTEM VENTING.
The successful development of hermetically sealed refrigeration compressors has completely sealed the compressor's
moving parts and electric motor inside a common housing,
minimizing refrigerant leaks and the hazards sometimes associated with moving belts, pulleys or couplings.
Fundamental to the design of hermetic compressors is a
method whereby electrical current is transmitted to the compressor motor through terminal conductors which pass
through the compressor housing wall. These terminals are
sealed in a dielectric material which insulates them from the
housing and maintains the pressure tight integrity of the hermetic compressor. The terminals and their dielectric embedment are strongly constructed, but are vulnerable to careless compressor installation or maintenance procedures and
equally vulnerable to internal electrical short circuits caused
by excessive system contaminants.
T
O AVOID POSSIBLE INJURY, EXPLOSION OR DEATH, PRACTICE SAFE
HANDLING OF REFRIGERANTS.
In either of these instances, an electrical short between the
terminal and the compressor housing may result in the loss
of integrity between the terminal and its dielectric embedment. This loss may cause the terminals to be expelled,
thereby venting the vaporous and liquid contents of the compressor housing and system.
A venting compressor terminal normally presents no danger
to anyone, providing the terminal protective cover is properly
in place.
If, however, the terminal protective cover is not properly in
place, a venting terminal may discharge a combination of
(a ) hot lubricating oil and refrigerant
(b ) flammable mixture (if system is contaminated
with air)
in a stream of spray which may be dangerous to anyone in
the vicinity. Death or serious bodily injury could occur.
Under no circumstances is a hermetic compressor to be electrically energized and/or operated without having the terminal
protective cover properly in place.
See Service Section S-17 for proper servicing.

LOCATION & CLEARANCES
NOTE: To ensure proper condensate drainage, unit must be installed in a level position.
In installations where the unit is installed above ground level
and not serviceable from the ground (Example: Roof Top
installations) the installer must provide a service platform for
the service person with rails or guards in accordance with local
codes or ordinances.
GPC/GPH13[24-60]M**
NOTE: Roof overhang should be no more than 36" and
provisions made to deflect the warm discharge air out from the
overhang.
Minimum clearances are required to avoid air recirculation and
keep the unit operating at peak efficiency.
WARNING
TO PREVENT POSSIBLE DAMAGE, THE UNIT SHOULD
REMAIN IN AN UPRIGHT POSITION DURING ALL
RIGGING AND MOVING OPERA TIONS. TO F ACILITA TE
LIFTING AND MOVING IF A CRANE IS USED, PLACE
THE UNIT IN AN ADEQUA TE CABLE SLIDE.
Refer to Roof curb Installation Instructions for proper curb installation. Curbing must be installed in compliance with the
National Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging
unit, center of gravity will cause condenser end to be lower
than supply air end.

NOTE: To ensure proper condensate drainage, unit must be installed in a level position.
The connecting ductwork (Supply and Return) can be connected
for horizontal discharge airflow. In the down discharge applications, a matching Roof Curb (PGC101/102/103) is recommended.
A return air filter must be installed behind the return air grille(s)
or provision must be made for a filter in an accessible location
within the return air duct. An internal filter rack (GPH13MFR102
& 103) and an external filter rack (GPGHFR101-103) are also
available as accessories. The minimum filter area should not
be less than those sizes listed in the Specification Section.
Under no circumstances should the unit be operated without
return air filters.
A 3/4" - 14 NPT drain connector is provided for removal of condensate water from the indoor coil. In order to provide proper
condensate flow, do not reduce the drain line size.
Refrigerant flow control is achieved by use of restrictor orifices.
These models use the FasTest Access Fitting System, with a
saddle that is either soldered to the suction and liquid lines or
is fastened with a locking nut to the access fitting box (core)
and then screwed into the saddle. Do not remove the core
from the saddle until the refrigerant charge has been
removed. Failure to do so could result in property damage or personal injury.
The single phase units use permanent split capacitors (PSC)
design compressors. Starting components are therefore not
required. A low MFD run capacitor assists the compressor to
start and remains in the circuit during operation.

PRODUCT DESIGN
The outdoor fan motor is a single phase capacitor type motors.
Air for condensing (cooling) is drawn through the outdoor coil
by a propeller fan, and is discharged vertically out the top of
the unit. The outdoor coil is designed for .0 static. No additional restriction (ductwork) shall be applied.
Conditioned air is drawn through the filter(s), field installed,
across the evaporator coil and back into the conditioned space
by the indoor blower.
COMPRESSORS
Some GPC/GPH series package units use the Compliant Scroll
compressor, instead of traditional reciprocating compressors.
Still other models use reciprocating compressors.
A scroll is an involute spiral which, when matched with a mating scroll form as shown, generates a series of crescent shaped
gas pockets between the two members.
During compression, one scroll remains stationary (fixed scroll)
while the other form (orbiting scroll) is allowed to orbit (but not
rotate) around the first form.
• Compliant Scroll compressors are more tolerant of liquid
refrigerant.
NOTE: Even though the compressor section of a Scroll
compressor is more tolerant of liquid refrigerant, continued
floodback or flooded start conditions may wash oil from the
bearing surfaces causing premature bearing failure.
• Compliant Scroll compressors use white oil which is compatible with 3GS. 3GS oil may be used if additional oil is
required.
• Compliant scroll compressors perform "quiet" shutdowns
that allow the compressor to restart immediately without
the need for a time delay. This compressor will restart even
if the system has not equalized.
NOTE: Operating pressures and amp draws may differ from
standard reciprocating compressors. This information can
be found in the unit's Technical Information Manual.
INDOOR BLOWER MOTOR
Some GPC/GPH model package units use a GE X13TM blower
motor while others use the standard PSC type blower motor.
The GE X13TM motor is a 3 Phase brushless DC (single phase
AC input), ball bearing construction motor with an integral control module with an internal FCC B EMI filter.
The GE X13TM motor is continuously powered with line voltage.
The switched 24 volt control signal is controlled by the thermostat.
As this motion occurs, the pockets between the two forms are
slowly pushed to the center of the two scrolls while simultaneously being reduced in volume. When the pocket reaches
the center of the scroll form, the gas, which is now at a high
pressure, is discharged out of a port located at the center.
During compression, several pockets are being compressed
simultaneously, resulting in a very smooth process. Both the
suction process (outer portion of the scroll members) and the
discharge process (inner portion) are continuous.
Some design characteristics of the Compliant Scroll compressor are:
