QwikSwap X3 ECM Blower Motors
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.
-
Verify that you have a Constant Torque Blower motor such as an X13® or SelecTech® Constant Torque ECM motor.
-
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 unplug it).
-
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 capacitor in a location that protects the terminals from a short circuit or ground fault.
-
Identify a good mounting location with sufficient clearance or use the supplied self-drilling sheet metal screws to attach the mounting bracket.
Unit may be mounted flat without the mounting bracket using the four mounting tabs/holes on the PCB backer board and four sheet metal screws. -
Install the power and control wires were removed from the the matching terminals were removed from the the matching terminals
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 QwikSwap X3 board. -
Connect the PSC blower motor power leads (HIGH, MED, LOW, COM) to the corresponding output terminals (HIGH, MED, LOW, COM) on the QwikSwap board.
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 QwikSwap 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 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 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. -
To activate a 3-minute delay after break (which will keep the blower operating for 3 minutes after the thermostat stopped the call for heating or cooling), connect the R terminal of the QwikSwap X3 board to the red thermostat wire (24-volt hot leg side of the transformer).
If the R terminal on the QwikSwap X3 board is left unconnected the X3 will still function properly, however there will be no delay after break.
-
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.
