7.1 Maintenance
DANGER!
Work on containers involves the danger of intoxication and
suffocation. No work is allowed to be carried out unless by
taking suitable personal protective measures (e.g. protective
breathing apparatus, protective clothing etc.).
When used properly, the level sensors work maintenance-free. They
must be subjected to visual inspection within the context of regular
maintenance, however, and included in the vessel pressure test.
Repairs must only be carried out by the manufacturer.
Perfect functioning of the level sensors can only be guaran-
teed when original accessories and spare parts are used.
