CAUTION

Installation Instructions
-
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.
SHAFT SIZE/ROTATION| / CW CCW
---|---
FRAME SIZE:|
VOLTAGE:|
HORSEPOWER:| -
Tnstall 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 to mount the QwikSwap X1 board.
-
Install the power and control wires that were removed from the old motor onto the matching terminals of the QwikSwap board. Refer to the wiring diagram created in Step 3 for proper connection locations.
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® board. -
Connect the PSC blower motor power leads, either HIGH, MED or LOW, along with the COMMON, to the corresponding output terminals (SPEED, COM) on the QwikSwap board.
If the PSC motor leads are not insulated, then insulated terminals will have to be installed on the PSC motor wires.
If the PSC motor power connection uses ¼ inch quick disconnect terminals
instead of wire leads from the motor, then two power leads from the QwikSwap
X1 to the PSC motor will need to be fabricated.
Use a minimum of 14-gauge wire with insulated ¼ inch female quickdisconnects
at each end to connect the two power leads from the QwikSwap X1 board to the
PSC motor.
WARNING: Do not jumper the motor windings.
-
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 X1 board to the red thermostat wire (24-volt hot leg side of the transformer) and remove the jumper.
-
Bundle any excess wires to avoid interference with
the blower motor. -
Reconnect power.
