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