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 appropri-
ate. Particularly harsh applications or heavy duty operation, such as high dust loads in the environ-
ment or in the process gas, other contamination or ingress of process material, can make it neces-
sary to shorten the maintenance intervals significantly.
