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.
1
Turn off power.
Verify that you have a Constant Torque Blower
2
motor such as an X13® or SelecTech® Constant
Torque ECM motor.
3 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
(if they are part of a
molded plug, simply

5 Install a new Permanent
Split Capacitor (PSC)
Blower motor with the
specifications noted in
Step 4. Properly ground
the motor and install the
capacitor in a location that
protects the terminals from a
short circuit or ground fault.

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 QwikSwap 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 QwikSwap board
together and connect them to the low speed tap on the motor.
WARNING: Do not jumper the motor windings.
Mount the QwikSwap

board to its mounting bracket
or mount flat using PCB backer
board tabs/holes
!
Secure the QwikSwap to the bracket using the
supplied plastic clips.
Press the clips through the bracket holes until
the clips snap in place.
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
with
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.
