PRODUCT DESIGN
*PC Package Cooling Units are designed for outdoor instal-
lations only in either residential or light commercial applica-
tions.
The connecting ductwork (Supply and Return) can be con-
nected for either horizontal or vertical airflow. In the vertical
application a matching Roof Curb 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 loca-
tion within the return air duct. The minimum filter area should
not be less than those sizes listed in the Specification Sec-
tion. Under no circumstances should the unit be operated
without return air filters.
A 3/4" PVC pipe is provided for removal of condensate water
from the indoor coil In order to provide proper condensate
flow, a drain trap is supplied and shipped loose inside the
unit for field installation. (Do not reduce the drain line size.)
Refrigerant flow control is achieved by use of restrictor ori-
fices. GPC units 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 re-
move the core from the saddle until the refrigerant
charge has been removed. Failure to do so could re-
sult in property damage or personal injury.
The single phase units use permanent split capacitor (PSC)
design compressors. Starting components are therefore not
required for these units. A low microfarad run capacitor assists
the compressor to start and remains in the circuit during
operation.
The outdoor fan and indoor blower motors are single phase

capacitor type motors with the exception of the *PC1360H41**
units which have EEM indoor blower motors that are energized
by a 24V signal from the thermostat and are constant torque
motors with very low power consumption. The EEM features
an integral control module.
Air for condensing (cooling cycle) 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 coil and back into the conditioned space by the
indoor blower.
APC1324H41C*,*PC13[30-60]H41** use Copeland Scroll
Compressors. (APC1324H41CA uses Scroll Compressors
and GPC1324H41CA uses Rotary Compressors.) There are
a number of design characteristics which are different from
the traditional reciprocating compressors.
-
Due to their design Scroll Compressors are inherently
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.
-
These Scroll Compressors use "POE" or polyolester oil
which is NOT compatible with mineral oil based lubricants
like 3GS. "POE" oil must be used if additional oil is
required.
-
Operating pressures and amp draws may differ from
standard reciprocating compressors. This information may
be found in the "Cooling Performance Data" section.
