7.1 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 ex-
tended (except safety component tests) 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.
