11.1
To reduce the risk of personal injury, do not bend the
blade flanges when installing the flanges, balancing
the blades, or cleaning the fan. Do not insert foreign
objects between rotating fan blades.
Make sure the three rubber grommets are firmly seated
on each of the blade flanges. Then mount the blade
flanges to the fan blades using three M5 x 6 washer
head blade screws per blade (Figure 19).
11.2
Mount one blade assembly to the motor hub by mating
the alignment post (Figure 20) of the flange with one of
the alignment slots in the motor hub (Figure 20).
Then tighten the two captive screws in the flange to
secure the flange to the motor hub.
Repeat this procedure for the other four blade
assemblies. Make sure all screws are tightened.
