Maintenance, Service and Repair

Prior to maintenance, service or repair, ensure that:
- Power supply is interrupted (all-pole circuit breaker).
- Fan impeller has come to a complete standstill
- Observe personnel safety regulations!
- Should the supply cable be damaged, it must be
replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
The fan should be cleaned when necessary, at least
1/year to avoid imbalance and unnecessary damage
to the bearings. A filter will prolong the time interval
between each 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. Ensure
that the fan impeller's balance weights are not moved
or the fan impeller distorted. Listen for abnormal
operating noise.
Resetting of the thermal trips
Manual thermal trips (SP1) are reset by disconnecting
the mains for approx. 10-20 min.
Fans with external leads for thermal trips (TK) are
reset from the external motor protection. This
protection may not have automatic resetting.
Make sure the fan has not been blocked or that the
motor protection has tripped. Contact the supplier if
the motor does not start after controlling and/or
resetting the motor protection.
