SELECTION PROCEDURE (WITH EXAMPLE)1. Determine cooling and heating requirementsat design conditions:Given:Required Cooling Capacity (TC) 34,000 Btuh. . . . . . .Sensible Heat Capacity (SHC) 24,000 Btuh. . . . . . . .Required Heating Capacity 12,500 Btuh. . . . . . . . . . .Condenser Entering Air Temperature 95F(35C). . . .Indoor−Air Temperature 80F (26C) edb . . . . . . . . . .
67F (19C) ewbEvaporator Air Quantity 1200 CFM. . . . . . . . . . . . . . . . .External Static Pressure 0.20 IN. W.C.. . . . . . . . . . . . .Electrical Characteristics 230−1−60. . . . . . . . . . . . . . . .
2. Select unit based on required coolingcapacity.Enter Net Cooling Capacities table at condenser enteringtemperature of 95F (35C), indoor air entering at 1200 cfmand 67F (19C) ewb (entering wet bulb). The unit will providea total capacity of 34,200 Btuh and a SHC of 24,500 Btuh.
3. Select electric heat.The required heating capacity is 15,000 Btuh.Determine additional electric heat capacity in kW.15,000 Btuh = 4.4kW of heat required 3,414 Btuh/kW
Enter the electric Heater Packages table for 208/240,single−phase, 36 unit. The 5 kW heater at 240v most closelysatisfies the heating required. To calculate kW at the 208v,multiply the heater kW by multiplication factor 0.75 found in theWattage Multiplication Factors table.5 kW x 0.75 = 3.75 kW3.75 kW x 3414 = 12802.50 Btuh
4. Determine fan speed and power require-ments at design conditions.Before entering the air delivery tables, calculate the total staticpressure required. From the given example, the Wet CoilPressure Drop Table, and the Filter Pressure Drop Table:External Static Pressure 0.200 IN. W.C.Filter 0.000 IN. W.C.Wet Coil Pressure Drop 0.130 IN. W.C.Total Static Pressure 0.330 IN. W.C.Enter the table for Wet Coil Air Delivery—horizontal discharge,230. At 0.33 IN. W.C. ESP (external static pressure) andmedium speed, the fan will deliver 1293 cfm. Adjusting for208v, the motor delivers 114 cfm (deduct 10%).
5. Select unit that corresponds to powersource available.The Electrical Data Table shows that the unit is designed tooperate at 208−1−60.

APPLICATION DATACondensate trap — A 2−in. (50.8 mm) condensate trap mustbe field supplied.Ductwork — Secure downflow discharge ductwork to roofcurb. For horizontal discharge applications, attach ductwork tounit with flanges.To convert a unit to downflow discharge — Units areequipped with factory−installed inserts in the downflowopenings. Removal of the inserts is similar to removing anelectrical knock−out.
Maximum cooling airflow — To minimize the possibility ofcondensate blow−off from the evaporator, airflow through theunits should not exceed 450 cfm per ton.Minimum cooling airflow — Minimum cooling airflow is 350cfm per ton.Minimum ambient cooling operation temperature — Allstandard units have a minimum ambient operating temperatureof 40�F (4�C). With accessory low ambient temperature kit,units can operate at temperatures down to 0�F (−17�C).

CONTROLSOperating sequenceCooling — When the system thermostat calls for cooling, 24 Vis supplied to the “Y” and “G” terminals of the thermostat. Thiscompletes the circuit to the contactor coil (C) and indoor(evaporator) fan relay (IFR). The normally open contacts ofenergized C close and complete the circuit throughcompressor motor (COMP) to outdoor (condenser) fan motor(OFM). Both motors start instantly. The set of normally opencontacts of energized IFR close and complete the circuitthrough IFM. The IFM starts instantly.On the loss of the thermostat call for cooling, 24 V is removedfrom both the “Y” and “G” terminals (provided the fan switch isin the “AUTO” position) de−energizing the compressorcontactor and opening the contacts supplying power tocompressor/OFM. After a 90−second delay, the IFM shuts off.If the thermostat fan selector switch is in the “ON” position, theIFM will run continuously. For the 460 V units there is a stepdown autotransformer supplying 230 V to the Indoor FanMotor.NOTE: On units with a Time Guard II device: Once thecompressor has started and then stopped, it cannot berestarted again until 5 minutes have elapsed.Heating — If accessory electric heaters are installed, on a callfor heat, circuit R−W is made through the thermostat contacts.Circuit R−G is made which energizes the IFR. If the heatersare staged, then the thermostat closes a second set ofcontacts (W2) when second stage is required. Whenthermostat is satisfied, contacts open, deenergizing the heaterrelay and the IFR.
