Installation Instructions
To replace Constant Torque ECM Blower Motors with a Permanent Split Capacitor
(PSC) Motor and Variable Speed Control Board
CAUTION
To prevent death, injury, or property damage, read and follow all instructions and warnings, including labels shipped with or
attached to unit.
WARNING
Improper installation, adjustment, alteration, service maintenance, or use can cause explosion, fire, electrical shock, or other
conditions that could cause personal injury or property damage. For use by qualified technicians only.
Turn off power
.
Note the terminal location and corresponding
color of each wire that connects to the blower
motor.
A reference diagram is shown below for
convenience. Disconnect these wires from the motor
Identify a good mounting location
with
sufficient clearance or use the supplied
self-drilling sheet metal screws to attach
the mounting bracket.
Verify that you have a Constant Torque Blower
motor
such as an X13® or SelecTech® Constant
Torque ECM motor.
Remove the old blower motor and note the shaft
size, frame size (typically 48Y) operating voltage,
direction of rotation and motor horsepower.
Install a new Permanent
Split Capacitor (PSC)
Blower motor with the
specifications noted in
Step 4
. Properly ground
the motor and install the
WIRING
DIAGRAM
!
!
Install the power and control wires that
were removed from the old motor onto
When using the optional QT6001
humidity sensor, connect the
sensor following the QT6001
installation instructions.
Using the supplied tie wraps, bundle any excess wires
to avoid interference with the blower.
Reconnect power.
Connect the PSC blower motor power leads
(HIGH, MED, LOW, COM) to the corresponding
output terminals (HIGH, MED, LOW, COM) on the
Qwik
Swap board.
The terminals on the wires
that were removed from the
old motor
MUST BE FULLY
INSULATED
or part of a molded
plug that will plug directly into
the Qwik
Swap
X3
board.
If the new PSC blower motor has quick disconnect terminals instead of
wires, you will have to fabricate the four wires (Minimum 14 gauge) with
quick disconnect terminals at each end to connect the High, Medium, Low
and Common connections from the Qwik
Swap
to the PSC motor. Eight
insulated 1/4 inch female quick disconnect terminals have been provided.
If the new blower motor has more than three speeds, use the highest,
lowest and one of the mid-range speeds.
If the new blower motor only has two speed taps, jumper the low- and
medium-speed quick disconnect connectors on the Qwik
Swap
board
together and connect them to the low speed tap on the motor.
If the PSC motor
leads do not
have insulated
terminals, four
insulated 1/4
inch female
quick disconnect
terminals have
been provided to
connect the PSC
power leads to the
Qwik
Swap
Board.

Attach the thermistor to an evaporator return
bend near the coil inlet.
Route the thermistor wire to the evaporator, and
using the supplied loop clamp,
attach the thermistor to
any return bend
near the coil inlet
.
Secure the clamp using the supplied
plastic ratchet rivet.
For furnace systems, route the
thermistor wire outside of the
ignition chamber by drilling a 5/16” hole
and using the supplied grommets.
