NOTE: For installations not indicated in the Temperature Rise NOTE: The Temperature Rise Tables can also be used to tables, the following formula is to be used: determine the air handler airflow delivery. When using these tables for this purpose, set the room thermostat to maximum TR = (kW x 3412) x (Voltage Correction) / (1.08 x CFM) heat and allow the system to reach steady state conditions. Insert 2 thermometers, one in the return air and one in the supply Where: TR = Temperature Rise air. The temperature rise is the supply air temperature minus the room air temperature. kW = Heater Kit Actual kW Use HKR specification sheets to determine the HKR available for 3412 = Btu per kW a given air handler.

Voltage Correction = 96 (230 Supply Volts)

= 92 (220 Supply Volts)

= 87 (208 Supply Volts)

1.08 = Constant

CFM = Measured Airflow

Use only on 15 and 20 kW models. Controls shown with utilities in ON position and thermostat in OFF position. 3. For outdoor thermostat operation of 2nd-stage heat, cut PJ2 and add OT18-60 to OTC and OT2. 4. For single-stage cooling applications, connect the thermostat to Y/Y2 only, tape or remove Y1 connection, connect condensing unit to YCON and C. 5. When humidstat is provided, cut PJ6. Thermostat opens on humidity rise. 6. Red wires to be on transformer Terminal 3 for 240 volts and on Terminal 2 for 208 volts. 7. See composite wiring diagrams in installation instructions for proper low voltage connections and details on compatible thermostats and their connections. 8.

23 AIR HANDLER MAINTENANCE ■ Inspect air filters at least once a month and replace or clean WARNING as required. Dirty filters are the most common cause of inadequate heating or cooling performance. HIGH VOLTAGE! ■ Replace disposable filters. Cleanable filters can be cleaned by soaking in mild detergent and rinsing with cold water. Disconnect ALL power before servicing.
