8. Maintenance
The instruments are maintenance-free.
The indicator and switching function should be checked once or twice every year.
For this the instrument must be disconnected from the process to check with a
pressure testing device.
Repairs must only be carried out by the manufacturer.
9. Dismounting, return and disposal
WARNING!
Residual media in dismounted measuring instruments can result
in a risk to persons, the environment and equipment.
Take sufficient precautionary measures.
9.1 Dismounting
Only disconnect the measuring instrument once the system has been depressu-
rised and the power disconnected!
If necessary, the measuring line must have strain relief.
9.2 Return
Wash or clean the dismounted measuring instrument before returning it, in order
to protect personnel and the environment from exposure to residual media.

Incorrect disposal can put the environment at risk. Dispose of instrument
components and packaging materials in an environmentally compatible way and
in accordance with the country-specific waste disposal regulations.
