Use the following formula to determine the percent voltage imbalance. % Voltage Imbalance = 00 x max voltage deviation from average voltage average voltage LEGENDS AND NOTES NOTES:. Rated in accordance with ARI Standards 20/240, latest revision (for sizes 090 & 20) or 360, latest revision (for size 0). 2. ARI ratings are net values, reflecting the effects of circulating fan heat. 3. 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--3--60. AB = 42 v Average Voltage = 42 + 464 + 4 BC = 464 v 3 AC = 4 v 37 = 3 = 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 =.3% 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.

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 -- If Accessory or Optional Heater is Installed) Upon a call for heating through terminal W, IFC and heater contactor no. (HC) are energized. On units equipped for 2 stages of heat, when additional heat is needed, HC2 is energized through W2. 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. See figures below for information on field--installed concentric ductwork when applicable. 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. 3. 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 300 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. To operate at lower outdoor--air temperatures, see Trade Prices or contact your local representative for appropriate accessory combinations for specific applications. 9. MAXIMUM OPERATING OUTDOOR -AIR TEMPERATURE -- For cooling, this temperature is 20 F for 80, 2 F for 240 size, and 2 F for 300 size. Refer to Cooling Capacities tables on pages 20 and 2 for further details. 0. 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. GUIDE SPECIFICATIONS: PAE80-240 CABINET: The cabinet shall be made of sturdy baked enamel coated galvanized steel.
