LV Heat Pump Series
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.

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.
