7.1 Maintenance
In general, thermowells are maintenance-free.
We recommend a visual check of the thermowell for leaks and damages at regular intervals.
Make sure that the seal is in perfect condition!
Repairs should only be carried out by the manufacturer or, following prior consultation, by
correspondingly qualified skilled personnel.

personnel and the environment from exposure to residual media.
■ Residual media in the dismounted thermowell can result in a risk to persons, the
environment and equipment. Sufficient precautionary measures must be taken.
