Important
Even if your fan is more that 2.30 m above the ground, care must still be taken care that the
blades are free to turn and no objects can enter their radius of action.
Maintaining you fan
You increase the life of your fan by heeding the following notes:
1. Check the various ceiling fixing parts and bracket twice a year.
Some of the parts on the fan components can have play.
2. Never use water for cleaning the motor or other electrical parts; this would lead to a short
circuit.
3. Use a soft cloth for cleaning the blades and housing.
4. Greasing the bearings is not necessary, the bearings are permanently lubricated.
Do not forget to check that the earth connection lead has been correctly connected to the
output terminal block and between all metal parts (connect the push-on contact to every earth
symbol).
Notes for removing faults
Fault
The fan does not
start.
The fan is noisy.
The fan vibrates
too much.
Important:
Opening up and repairing the unit may only be carried out by a specialist!
Remedy
Check the fuses/trips at the main box and other connections.
Check the fan connection to the mains.
Check that fuses/trips in the connection box are correctly inserted.
Check that all bolts and screws have been tightened.
Run in the fan and the bearings for 24 hours. Most noises disappear after
this time.
All blades have been weighed and grouped according to weight.
Their density can vary and therefore cause vibration even when all blades
are of the same weight. The following methods can contribute to preventing
most vibrations. Check the vibration before each procedure. Please note
that a small amount of vibration is normal and does not pose a problem.
Most vibrations occur when one of the blades is not in alignment with
the others. Aligning the blades is simply carried out with the aid of a flat
ruler. Place the ruler vertically upwards against the ceiling and alongside
the blade tip. Mark the distance between the blade side and ceiling.
Turn the blades slowly by hand and carry out the same measurements with
the other blades. If one of the blades is not correctly aligned, it can be
remedied by lightly pressing their holders upwards or downwards in order
to align them with the others.
Check that the mounting plate is firmly anchored to the ceiling.
