115V/208V/480V Airflow Performance Data—RHSL (PSC Motor)
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.
• All 115V PSC motors are shipped on high speed.
• 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.
• All 480V PSC motors are shipped on high speed.
• If the application external static is less than 0.5" WC, adjust the motor speed to
the low static speed as described below for 3-ton through 4-ton air handlers.
• Unplug the black motor wire off the relay and remove the cap from
the red motor wire.
• Plug the red motor wire to the relay and connect the black motor
wire with the yellow motor wire.
• For 5-ton air handler, unplug the black motor wire off the relay and plug in the red
motor wire, then cap the black motor wire. There is no yellow motor wire on 5-ton
air handler.
WARNING: Do not connect red motor wire with yellow motor wire in any circumstance on
480V PSC motors. Connecting red motor wire with yellow motor wire will result in
permanent motor damage.
• 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)
