Notes: • All 208/240V PSC motors have voltage taps for 208 and 240 volts.
• All 208/240V PSC motors are shipped on high speed and 240 volts.
• If the application external static is less than 0.5" WC, adjust the motor speed to the low static speed as described below:
• Unplug the black motor wire off the relay on the control board and plug in the red motor wire.
• Replace the cap on the black motor wire.
• Voltage change (208/240V motors):
• Move the orange lead to transformer 208V tap from 240V tap. Replace the wire cap on 240V tap.
• Unplug the purple motor wire off the transformer and plug in the yellow motor wire.
• Replace the cap on the purple motor wire.
• The above airflow table lists the airflow information for air handlers without heater and air handler with maximum heater allowed for each model.
• The following formula can be used to calculate the approximate airflow, if a smaller (N kW) than the maximum heater kit is installed.
Approximate Airflow = Airflow without heater - (Airflow without heater - Airflow with maximum heater) x (N kW/maximum heater kW)
