Balancing – Wobbling problems during fan
operation
If the fan body wobbles during its operation, this is not a sign
of malfunctioning (even if it wobbles a few centimeters). To
reduce wobbling, you can, while the fan is off:
1. Check that all blades are properly fastened by tightening
their screws.
2. Check the distance between each blade and the ceiling. Me-
asurements to the ceiling can be carried out as shown in
the following diagram. If variations exist and you have al-
ready correctly tightened the screws, check that all blades
have the same shape. If any of them have a shape that is
visibly different, this may be causing an imbalance during
fan operation.
If you have completed the previous steps and the wobbling
has not resolved, you should apply dynamic balancing with
the kit provided, as explained below:
1. Turn the fan on to the highest speed so that the greatest
amount of wobbling is produced.
2. Turn off the fan. Select a blade and place a clip on it (see
diagram) halfway between the fastening and the far edge of
the blade.
3. Turn on the fan and check whether the wobbling has im-
proved or gotten worse. Turn it off once again and if the
wobbling has not improved, place the clip on another blade.
Repeat this process and determine on which blade it im-
proves the wobbling.
4. Leave the clip on the blade that produces the best results.
Move the clip forward or backwards on this blade until
finding the position that offers the best results.
5. Afterwards, remove the clip and place one of the weights
on the upper part of the center line of the blade at the
position where the clip was located.
