WARNING
WARNING
SYSTEM CONTAMINANTS, IMPROPER SERVICE PROCEDURE AND/OR PHYSICAL
ABUSE AFFECTING HERMETIC COMPRESSOR ELECTRICAL 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.

PRODUCT DESIGN
LOCATION & CLEARANCES
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.
*PH15[24-60]M41*
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 OPERATIONS. TO FACILITATE LIFTING AND MOVING IF A CRANE IS USED, PLACE THE UNIT IN AN ADEQUATE 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.
Roof Curb
*PH15[24-60]M4*
*PH Package Units are designed for outdoor installations only in either residential or light commercial applications.
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 for horizontal models only.
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 TXV. 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.
13
PRODUCT DESIGN
The outdoor fan motors are 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
The *PH15 4 and 5 ton M series package heat pump units use a two-stage scroll compressor. The two-step modulator has an internal unloading mechanism that opens a bypass port in the first compression pocket, effectively reducing the displace­ment of the scroll. The opening and closing of the bypass port is controlled by an internal electrically operated solenoid.
The ZPS two-step modulated scroll uses a single step of un­loading to go from full capacity to approximately 67% capac­ity. A single speed, high efficiency motor continues to run while the scroll modulates between the two capacity steps.
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:
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.
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.
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.
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.
14
INDOOR BLOWER MOTOR
GPH15 M series model package units use a GE X13TM 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 in the cooling and heat pump mode and the blower relay in the electric heat mode.
APH15 M series model package units use an ECM blower motor. These motors offer greater airflow flexibility as well as dehumidification. The airflow delivery for these models can be adjusted by changing the position of dip switches on a low voltage terminal board.
PRODUCT DESIGN
ELECTRICAL WIRING
The units are designed for operation at the voltages and hertz as shown on the rating plate. All internal wiring is complete. Ensure the power supply to the compressor contactor is brought to the unit as shown on the supplied unit wiring diagram. The 24V wiring must be connected between the unit control panel and the room thermostat.
WARNING
TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK, WIRING TO THE UNIT MUST BE PROPERLY POLARIZED AND GROUNDED.
WARNING
WARNING
TO AVOID THE RISK OF PROPERTY DAMAGE, PERSONAL INJURY OR FIRE, USE ONLY COPPER CONDUCTORS.
LINE VOLTAGE WIRING
Power supply to the unit must be N.E.C. Class 1, and must comply with all applicable codes. The unit must be electrically grounded in accordance with the local codes or, in their ab­sence, with the latest edition of the National Electrical Code, ANSI/NFPA No. 70, or in Canada, Canadian Electrical Code, C22.1, Part 1. A fused disconnected must be provided and sized in accordance with the unit minimum circuit ampacity.
The best protection for the wiring is the smallest fuse or breaker which will hold the equipment on line during normal operation without nuisance trips. Such a device will provide maximum circuit protection.
WARNING
DO NOT EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON THE UNIT DATA PLATE.
All line voltage connections must be made through weather proof fittings. All exterior power supply and ground wiring must be in approved weather proof conduit. Low voltage wiring from the unit control panel to the thermostat requires coded cable.
The unit transformer is connected for 230V operation. If the unit is to operate on 208V, reconnect the transformer primary lead as shown on the unit wiring diagram.
If it is necessary for the installer to supply additional line volt­age wiring to the inside of the package unit, the wiring must comply with all local codes. This wiring must have a minimum temperature rating of 105°C. All line voltage splices must be made inside the unit or heat kit control box.
