Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The intervals
given below are considered as starting values which should be shortened or extended as
appropriate. Particularly harsh applications or heavy duty operation, such as high dust loads in the
environment or in the process gas, other contamination or ingress of process material, can make it
necessary to shorten the maintenance intervals significantly.
