Repairs / maintenance

Attention!
•
Please read the Safety instructions chapter before working on the fan!
•
Before working on the fan, this must be disconnected from the power supply and secured against
switching back on!
•
No maintenance work at running fan!
•
Allow maintenance work to be carried out by trained specialists only.
•
Any faults detected in the electric system/modules/operating equipment must be corrected immedi-
ately. If these faults are not corrected, the device/system is potentially very dangerous. The
device/system must therefore not be operated when it is faulty.
•
Wear safety shoes and gloves for handling!
•
Please observe the safety regulations and the worker´s protection rules by all maintenance and
service work (EN 50 110, IEC 364).
•
Fuses must always be only replaced; never repaired or bridged. The specifications for the max-
imum series fuse must always be adhered to (
circuit diagram may be used.
•
Generator operation can produce dangerous voltages
•
Keep the airways of the fan free - danger because of objects dropping out!
•
Watch out for vibration free motion!
•
The impeller is subject to natural wear depending on the area of application and the conveying
medium. Deposits on the impeller can lead to imbalance and damage (danger of permanent
fracture). The impeller can burst!
•
If highly aggressive media for which the product is not suited are conveyed, the severe corrosion
may result in the impeller breaking. Any impellers corroded in this way must be replaced immedi-
ately.
•
Deposits on the motor, particularly on the cooling vanes and in recesses on the rotor, can lead to
reduced cooling performance and the motor switching off prematurely. For this reason, remove
deposits quickly (
•
Maintenance interval in accordance with the degree of contamination of the impeller!
•
Check the fan at regular intervals (recommendation: every 6 months) for mechanical oscillations.
Observe the limits specified in ISO 14694 and, if they are exceeded, implement remedial measures
(e.g. rebalancing by specialist staff).
•
Check the impeller, in particular the weld-seams, for possible cracks.
