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.
