E. Connect the electrical leads to the new Motor assembly. Make sure all connections are clean
and tight.
F. Lower the Motor assembly into place and fasten it securely with the four mounting screws.
G. Apply a bead of silicone sealant (available at any plumbing or hardware store) around the edges
of the Motor Mount. Smooth it down with your finger. Remove any excess sealant but make
sure that the entire edge of the Motor Mount is completely sealed to prevent any water from
leaking from the Proofer onto the new Proofer Motor.
H. Replace the Fan Blade/Blower Wheel on the Motor shaft. Tighten the set screw securely; a
loose Fan Blade/Blower Wheel will cause a later service problem.
I. Restore electrical power to the unit and test the new Proofer Motor assembly for proper
operation. Make sure the Fan Blade/Blower Wheel does not drag on the floor of the Proofer.
J. Replace the Proofer Element Cover and retest the Proofer Motor assembly. Make sure the Fan
Blade/Blower Wheel does not drag on the underside of the Element Cover.
