GE 20543 User Manual page 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 "Fan Blades
Assembly."
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
1-5. 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.
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. Adjust the clip on this blade as shown in the
illustration and operate the fan to find the position
where the clip gives the greatest improvement.
5. Remove the clip, clean the area where the weight is
to be added, and install a balancing weight to the top of
the blade along the centre line near the point where the
clip was positioned on the blade.
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.
