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 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 significant-
ly.
