NOTE:
• All 208/240V PSC motors have voltage taps for 208 and 240 volts.
• All 208/240V PSC motors have shipped on high speed and for 240 volt applications.
• 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. 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 with maximum heater allowed for each model.
