10.3 Maintenance, service
DANGER
Loss of explosion protection!
Basically the fan may be repaired at the manufacturer only! Failure to this would expire the ATEX approval
(basically, always consult the manufacturer). Exceptions are non-relevant components. They can be
performed on site by qualified personnel.
The fan is by built-in for-life lubricated ball bearings as far as possible low-maintenance product. After their life time
(app. 30.000 to 40.000 h), a replacement of the bearings is necessary. Observe attached instructions of motor manu-
facturer.
Pay attention to a non-typical noise from bearings.
For damages (e.g. damage to winding) please contact our Service Department. Repairs may be accomplished
only in the company of manufacturer and by the manufacturer. You find the address on the back of these op-
erating instructions.
Maintenance and check points of fans similarly to VDMA 24186-1 (type, scope and maintenance intervals to be speci-
fied in dependence of use and operating conditions).
