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.
