Given: Required Cooling Capacity (TC) 34,000 Btuh....... Sensible Heat Capacity (SHC) 25,000 Btuh........ Required Heating Capacity 15,000 Btuh........... Outdoor Entering−Air Temperature 95°F (35°C)..... Indoor Entering−Air Temperature 80°F edb (26.7°C); 67°F (19.4°C) ewb Indoor−Air Quantity 1200 CFM.................... External Static Pressure 0.20 IN. W.C.............. Electrical Characteristics (V−Ph−Hz) 230−1−60..... B. SELECT UNIT BASED ON REQUIRED COOLING CAPACITY (3−TON EXAMPLE) Enter Cooling Capacities table at condenser entering temperature of 95°F (35°C), indoor air entering at 1200 CFM and 67°F (19.4°C) ewb. The 36 unit provides a total cooling capacity of 34,500 Btuh and a sensible heat capacity of 26,040 Btuh. For indoor−air temperature other than 80°F (26.7°C) edb, calculate sensible heat capacity correction, as required, using the formula found following the Cooling Capacities tables. NOTE: Unit ratings are net capacities. C. SELECT ELECTRIC HEAT. The required heating capacity is 15,000 Btuh (given). Determine the electric heat capacity in kW. 15,000 Btuh 3414 Btuh/kW = 3.8 kW of heat required Enter the Accessory Electric Heater table on page 4 for 208/230, single−phase, 036 unit. The 5−kW heater at 240v most closely satisfies the heating required. To calculate kW at 230 V, multiply the heater kW by multiplication factor 0.92 found in the Multiplication Factors table on page 4. 5 kW x 0.92 = 4.6 kW 4.6 kW x 3414 Btuh/kW = 15,704 Btuh D. DETERMINE FAN SPEED AND POWER REQUIREMENTS AT DESIGN CONDITIONS. Before entering the air delivery tables, calculate the total static pressure required. From the given, Filter Pressure Drop table, and the Accessory Electric Heat Pressure Drop table find: External static pressure 0.20 IN. W.C. Filter 0.10 IN. W.C. Electric Heat 0.04 IN. W.C. Total static pressure 0.34 IN. W.C. Enter the table for Dry Coil Air Delivery — Horizontal Discharge. At 0.4 IN. W.C. external static pressure and medium speed, the motor delivers 1236 CFM. 7426 41 1707 05Specifications subject to change without notice.PERFORMANCE DATA Cooling Capacities 24 EVAPORATOR AIR

In compliance with NEC (National Electrical Code) requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be Power Supply fuse or circuit breaker. 2. Minimum wire size is based on 60 C copper wire. If other than 60 C wire is used, or if length exceeds wire length in table, determine size from NEC. *Heater capacity (kW) based on heater voltage of 208v & 240v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly. OPERATING SEQUENCE Cooling Operation With a call for cooling (Y/G), the contactor is energized which brings on the compressor and outdoor fan. The indoor fan is also energized. When the cooling demand is met, Y and G are de−energized shutting off the contactor. The indoor fan stops after a 60 second delay. Heating Operation With a call for heating (W2), the auxiliary or electric heat energizes along with the indoor blower. In case of staged heating, W3 is energized if the demand is not met. The highest airflow selected is run while the electric heat is in operation. When heating demand is met, W3 and W2 sequentially de−energize shutting off the indoor fan and the electric heater. Continuous Fan With the continuous indoor fan option selected on the thermostat, G is continuously energized keeping the indoor fan running at all times. APPLICATION DATA Condensate trap — A 2−in. (51 mm) condensate trap must be field supplied. 1” (25 mm) MIN. 2” (51 mm) MIN. TRAP OUTLET A08001 Maximum cooling airflow — To minimize the possibility of condensate blow−off from the evaporator, airflow through the units should not exceed 450 CFM/ton. Minimum cooling airflow — The minimum cooling airflow is 350 cfm/ton. Minimum cooling operating outdoor air temperature — All standard units have a minimum ambient operating temperature of 40°F (4.4°C). With accessory low ambient temperature kit, units can operate at temperatures down to 0°F (−17.8°C). Maximum operating outdoor air temperature — Maximum outdoor operating air temperature for cooling is 125°F (51.7°C). 15 426 41 1707 05Specifications subject to change without notice.
