NOTE: The PGS80--240 units have a low--pressure switch (standard) located on the suction side. NOTE: Minimum allowable temperature of mixed--air entering the heat exchanger during first--stage heating is 4F. There is no minimum mixed-- air temperature limitation during second--stage heating. For entering--air temperatures below 4 F both stages of heat muxt be energized together to minimize condensation issues and ensure proper unit operation. NOTES:. In compliance with NEC requirements for multimotor and combina-- tion load equipment (refer to NEC Articles 40 and 440), the over-- current protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced -Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent voltage imbalance. % Voltage Imbalance = 00 x max voltage deviation from average voltage average voltage 4 NOTES:. Rated in accordance with ARI Standards 20/240, latest revision (for sizes 090 & 20) or 60, latest revision (for size 0). 2. ARI ratings are net values, reflecting the effects of circulating fan heat.. Ratings are based on: Cooling Standard: 80F db, 67F wb indoor entering air temperture and 9F db air entering outdoor unit. IPLV Standard: 80F db, 67F wb indoor entering air temperture and 80F db entering air temperature. EXAMPLE: Supply voltage is 460----60. AB = 42 v Average Voltage = 42 + 464 + 4 BC = 464 v AC = 4 v 7 = = 47 Determine maximum deviation from average voltage. (AB) 47-42 = V (BC) 464-47 = 7 V (AB) 47-4 = 2 V Maximum deviation is 7 v. Determine percent voltage imbalance. % Voltage Imbalance = 00 x 7 47 =.% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT : If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

CONTROLS OPERATING SEQUENCE Cooling, Units Without Economizer -- When thermostat calls for cooling, terminals G and Y are energized. The indoor (evaporator) fan contactor (IFC) and compressor contactor no. (C) are energized, and evaporator--fan motor (IFM), compressor no., and condenser fan(s) start. The condenser--fan motor(s) runs continuously while unit is cooling. When the thermostat calls for a second stage of cooling by energizing Y2, compressor contactor no. 2 (C2) is energized and compressor no. 2 starts. Heating, Units Without Economizer NOTE: The PGS80--240 units have 2 stages of heat. When the thermostat calls for heating, power is sent to W on the IGC (integrated gas unit controller) board. An LED (light--emitting diode) on the IGC board will be on during normal operation. A check is made to ensure that the rollout switch and limit switch are closed. The induced--draft motor is then energized, and when speed is proven with the hall effect sensor on the motor, the ignition activation period begins. The burners will ignite within seconds. If the burners do not light, there is a 22--second delay before another --second attempt. If the burners still do not light, this sequence is repeated for minutes. After the minutes have elapsed, if the burners still have not lighted, heating is locked out. To reset the control, break 24--v power to the thermostat. When ignition occurs the IGC board will continue to monitor the condition of the rollout and limit switches, the hall effect sensor, as well as the flame sensor. If the unit is controlled through a room thermostat set for fan auto., 4 seconds after ignition occurs, the indoor--fan motor will be energized. If for some reason the overtemperature limit opens prior to the start of the indoor fan blower, on the next attempt, the 4--second delay will be shortened to seconds less than the time from initiation of heat to when the limit tripped. Gas will not be interrupted to the burners and heating will continue. Once modified, the fan on delay will not change back to 4 seconds unless power is reset to the control. When additional heat is required, W2 closes and initiates power to the second stage of the main gas valve. When the thermostat is satisfied, W and W2 open and the gas valve closes, interrupting the flow of gas to the main burners. If the call for W lasted less than minute, the heating cycle will not terminate until minute after W became active. If the unit is controlled through a room thermostat set for fan auto., the indoor--fan motor will continue to operate for an additional 4 seconds then stop. If the overtemperature limit opens after the indoor motor is stopped within 0 minutes of W becoming inactive, on the next cycle the time will be extended by seconds. The maximum delay is minutes. Once modified, the fan off delay will not change back to 4 seconds unless power is reset to the control. A LED indicator is provided on the IGC to monitor operation. The IGC is located by removing the side panel and viewing the IGC through the view port located in the control box access panel. During normal operation, the LED is continuously on. APPLICATION DATA. DUCTWORK -- Ductwork should be attached to the curb on all units. Interior installation may proceed before unit is set in place on roof. If ductwork will be attached to the unit, do not drill in condensate drain pan area -- leaks may result. 2. THRU--THE--CURB SERVICE CONNECTIONS -- Roof curb connections allow field power wires, control wires, and gas supply to enter through the roof curb opening.. THERMOSTAT -- Use of 2--stage cooling thermostat is recommended for all units. A 2--stage cooling thermostat is required on units with accessory economizer to provide integrated cooling. 4. HEATING--TO--COOLING CHANGEOVER -- All units are automatic changeover from heating to cooling when automatic changeover thermostat and subbase are used.. AIRFLOW -- Units are draw--thru on cooling and blow--thru on heating. 6. MAXIMUM AIRFLOW --To minimize the possibility of condensate blow--off from evaporator, airflow through units should not exceed 00 cfm/nominal ton on size 80--240 units. 7. MINIMUM AIRFLOW -- The minimum airflow for cooling is 00 cfm/nominal ton on size 80--240 units. 8. MINIMUM AMBIENT COOLING OPERATION TEMPERATURE Units are designed to operate at outdoor temperatures down to 40 F. 9. MAXIMUM OPERATING OUTDOOR--AIR TEMPERATURE -- For cooling, this temperature is 20 F for 80 unit and 2 F for 240 unit. Refer to Cooling Capacities tables. 0. HIGH ALTITUDE -- A change to the gas orifice may be required at high altitudes. Refer to Altitude Compensation charts.. MINIMUM TEMPERATURE -- Air entering the heat exchanger in heating must be a minimum of 0 F continuous and 4 F intermittent. For entering--air temperatures below 4 F both stages of heat must be energized together to minimize condensation issues and ensure proper unit operation. 2. INTERNAL UNIT DESIGN -- Due to the internal unit design (draw--thru over the motor), air path, and specially designed motors, the full horsepower (maximum continuous bhp) listed in the Physical Data table and the notes following each Fan Performance table can be utilized with extreme confidence. Using motors with the values listed in the Physical and Fan Performance Data tables will not result in nuisance tripping or premature motor failure. The unit warranty will not be affected. 7
