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. Measurements to the
ceiling can be carried out as shown in the following diagram. If variations exist
and you have already 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 improved 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 improves
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.
