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 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.
