FAN MOTOR OPTIONS
Permanent Split Capacitor Motors (PSC)
The standard motor for all LV series heat pumps is
a PSC motor. For all models other than 575 V
units, the supplied motor is a three speed motor.
575 V motors are single speed. If a speed change
is required, follow the instructions below:
1. Disconnect power to the heat pump.
2. For units with leaded motors, remove the front
access cover.
3. Remove the fan speed wire from the fan relay.
Clip the ¼” quick connect from the lead and
cap the unused lead.
4. Uncap the desired fan speed wire and
terminate with a ¼” quick connect. Connect to
the fan relay.
5. If the motor is a 460 V motor and the speed is
changed from high to medium or low, connect
the high speed motor lead to the orange
intermediate winding lead instead of simply
capping it.
Refer to the PSC motor performance tables for
heat pump blower performance with the PSC
motor option.
