9. ATTACHING THE FAN BLADES
CAUTION: Remove the five rubber shipping
blocks attached to the face of the motor.
These blocks keep the motor from shifting
during shipping and MUST be removed during
installation.
Step 1. Attach a blade to a blade bracket
using the screws and fiber washers provided.
(Fig. 16)
Make sure the blade is straight when set on
the blade bracket. Tighten each mounting
screw until the fiber washer is slightly
compressed. Repeat this procedure for each
blade.
Step 2. Attach each blade assembly to the
motor using the "Pre-Installed" mounting
screws in the blade bracket. (Fig 16)
10. INSTALLING THE MOUNTING PLATE
Step 1. Loosen the two screws on the
mounting ring attached to the motor shaft and
"remove" and save the third screw. (Fig. 17)
Step 2. Place the key hole slots on the
mounting plate over the two screws
previously loosened on the mounting ring.
Turn the mounting plate until is locks in place
at the narrow section of the key hole slots.
Tighten both key hole screws and replace the
third screw previously removed and tighten
securely.
