PRODUCT DESIGN
GPC 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 as- sists the compressor to start and remains in the circuit dur- ing operation.
The outdoor fan and indoor blower motors are single phase capacitor type motors with the exception of the GPC1360H41* units which have
Air for condensing (cooling cycle) is drawn through the out- door 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.
-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 toler- ant of liquid refrigerant, continued floodback or flooded start conditions may wash oil from the bearing surfaces causing premature bearing failure.
-Scroll Compressors use white oil which is compatible with 3GS oil which may be used if additional oil is re- quired.
-Operating pressures and amp draws may differ from stan- dard reciprocating compressors. This information may be found in the "Cooling Performance Data" section.
