PRODUCT DESIGN Locations and 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 or in their absence with the latest edition of the National Fuel Gas Code ANSI Z223.1.
PRODUCT DESIGN The single phase models 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. A/GPG16 three phase units use three phase compressors. Starting components and run capacitors are therefore not required.
PRODUCT DESIGN - 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. - Operating pressures and amp draws may differ from standard reciprocating compressors. This information may be found in the “Cooling Performance Data” section. All models of the A/GPG16 series package units use a 2 stage scroll compressor.
PRODUCT DESIGN Note: Junction box location shown is optional and is for illustration purposes only. WARNING TO AVOID THE RISK OF PROPERTY DAMAGE, PERSONAL INJUSRY OR FIRE, USE ONLY COPPER CONDUCTORS JUNCTION BOX 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.

L1-L2, L1-L3, and L2-L3 - If voltage is present, proceed to B. If voltage is not present, check breaker or fuses on main power supply.. B. T1-T2, T1-T3, and T2-T3 - If voltage readings are not the same as in "A", replace contactor. T3 T2 T1 CC VOLT/OHM METER L3 L2 5.
SERVICING Your unit comes with a 180-second anti-short cycle to prevent the compressor from starting and running backwards. MODELS EQUIPPED WITH A HARD START DEVICE A start capacitor is wired in parallel with the run capacitor to increase the starting torque. The start capacitor is of the electrolytic type, rather than metallized polypropylene as used in the run capacitor.
SERVICING WARNING Discharge capacitor through a 20 to 30 OHM resistor before handling. Capacitance (MFD) = 2650 X Amperage Voltage 4. Using an ohmmeter, check the motor windings for continuity to ground (pins to motor shell). If the ohmmeter indicates continuity to ground, the motor is defective and must be replaced. 5. Using an ohmmeter, check the windings for continuity (pin to pin). If no continuity is indicated, the thermal limit (over load) device may be open. Allow motor to cool and retest.
SERVICING High Voltage Connections 3/16" C L G N Ignition cannot occur at the venting terminal without the presence of contaminant air, and cannot occur externally from the venting terminal without the presence of an external ignition source. Therefore, proper evacuation of a hermetic system is essential at the time of manufacture and during servicing.
SERVICING NOTE: If an open compressor is indicated, allow ample time for the internal overload to reset before replacing compressor. S-17B GROUND TEST If fuse, circuit breaker, ground fault protective device, etc., has tripped, this is a strong indication that an electrical problem exists and must be found and corrected. The circuit protective device rating must be checked, and its maximum rating should coincide with that marked on the equipment nameplate.
SERVICING 4. Next check the molded plug. A. B. C. Voltage check: Apply control voltage to the plug wires (18 to 28 volt ac). The measured dc voltage at the female connectors in the plug should be around 15 to 27 vdc. Resistance check: Measure the resistance from the end of one molded plug lead to either of the two female connectors in the plug. One of the connectors should read close to zero ohms while the other should read infinity. Repeat with other wire.
SERVICING S-101 LEAK TESTING (NITROGEN OR NITROGEN-TRACED) WARNING To avoid the risk of fire or explosion, never use oxygen, high pressure air or flammable gases for leak testing of a refrigeration system. 1. Connect the vacuum pump, vacuum tight manifold set with high vacuum hoses, thermocouple vacuum gauge and charging cylinder as shown. 2. Start the vacuum pump and open the shut off valve to the high vacuum gauge manifold only.
SERVICING S-103 CHARGING WARNING REFRIGERANT UNDER PRESSURE! * Do not overcharge system with refrigerant. * Do not operate unit in a vacuum or at negative pressure.

SERVICING NOTE: The expansion valve will not need adjustment for most applications. Ensure system superheat is set within range listed on chart. COOLING OPERATION NOTE: Mechanical cooling cannot be reliably provided at ambient temperatures below 50° F. 1. Turn on the electrical power supply to the unit. 2. Place the room thermostat selector switch in the COOL position (or AUTO if available, and if automatic changeover from cooling to heating is desired). 3.
SERVICING During the "OFF" cycle, the high side pressure bleeds to the low side through the fixed orifice restriction device. Check equalization time as follows: 3. Observe the system while running a cooling performance test. If a shortage of refrigerant is indicated, then the system contains non-condensables. 1. Attach a gauge manifold to the suction and liquid line dill valves. S-114 NON-CONDENSABLES 2. Start the system and allow the pressures to stabilize. 3.
SERVICING rechecked for a pressure drop after the system has operated for a time. It may be necessary to use new tubing and form as required. NOTE: At least twelve (12) inches of the suction line immediately out of the compressor stub must be discarded due to burned residue and contaminates. INCLINED MANOMETER SUPPLY 1. Remove compressor discharge line strainer. 2. Remove the liquid line drier and expansion valve. 3 Purge all remaining components with dry nitrogen or carbon dioxide until clean.
SERVICING If the temperature within the furnace should exceed this setting, the control will open, de-energizing the ignition control which in turn will open the electrical circuit to the gas valve. The control will automatically reset when the temperature within the combustion chamber is sufficiently lowered. SUPPLY RETURN TSUPPLY HIGH VOLTAGE! Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present.
SERVICING AUX. LIMIT S-302 CHECKING FLAME ROLLOUT SWITCH APG/GPG units are equipped with a temperature-activated manual reset control. This control is mounted to the manifold assembly and is wired in series with the auxiliary limit and gas valve. The control is designed to open should a flame roll out occur. An over firing condition or flame impingement on the heat shield can also cause the control to open.
SERVICING When the limit switch re-closes, the induced draft motor runs through its post purge and the indoor blower goes through the heat off delay. If a call for heat exists when the limit switch re-closes, the control goes through a pre-purge period and then makes an ignition attempt. The indoor blower remains on (for the delay off time) during the re-ignition attempt. 1. If no voltage is measured on either side of control it indicates ignition control or wiring to control problem. 2.
