Maintenance, Service and Repair
Prior to maintenance, service or repair, make
sure that:
- Power supply is interrupted (all-pole circuit
breaker).
- Fan impeller has come to a complete
standstill
- Observe personnel safety regulations!
The fan should be cleaned when necessary, at
least 1/year to avoid imbalance and
unnecessary damage to the bearings. A filter
will further improve the time interval between
cleaning of the fan. (It is sometimes
recommended to install a filter guard). The fan
bearings are maintenance free and should only
be replaced if damaged. Do not use a high-
pressure cleaner (steam jet) when cleaning the
fan. Make sure the fan impeller's balance
weights are not moved or the fan impeller
distorted. Listen for abnormal operating noise.
The following applies in case the fan has
stopped:
- Try to restart the fan by cutting the power a
couple of minutes.
- Ensure that the impeller is not locked.
Possible obstruction to be removed after the
current has been switched off. Check that the
fan starts after reconnecting the current. If
the fan does not start, please contact your
place of purchase.
