FAN REMOVAL AND INSTALLATION
When reassembling parts, the cap screws must be installed through the untapped clearance holes as shown.
This will cause the blade to be pulled forward onto the tapered bushing, thus locking the parts securely onto
the motor shaft.
When fan servicing requires removal and installation of the blade, make sure the blade is removed and
reinstalled properly.
1. Lock out the fan power supply, and remove the fan guard and the venturi, as required on some models.
2. Remove the three cap screws from the clearance holes in the taper-lock bushing.
