Blade Balancing
16
The balancing kit should only be used if there is an
unacceptable amount of fan wobble after completing
all the steps in the user manual under “Attaching the
Fan Blades”.
1.
Turn the fan on and set the speed control setting to a
speed at which the wobble is the greatest.
2.
Turn off the fan and allow it to come to a complete
stop. Mark the blades with masking tape number
1-4. Select one blade and place the balance clip on it
halfway between the blade holder and the blade tip on
the trailing edge of the blade (fig. a) .
3.
Turn the fan on. Note whether the wobble has
increased or decreased. Turn the fan off, move the clip
to another blade, and retest. Repeat this procedure
on all blades noting the blade on which the greatest
improvement is achieved.
4.

6.
If the fan wobble problem has not been corrected,
you may wish to try to improve the balancing further by
using the balancing clip and additional weights.
5.
Clean the area on top of the blade near where the clip
is located. Install a balancing weight to the top of the
blade along the centre line (fig c).
