8. Maintenance and cleaning

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 or appropriately

qualied personnel.

Clean the instruments with a moist cloth (soap water).

Prior to cleaning, disconnect the instruments from the mains. Ensure that all

the parts are dry before the power is switched on again.

Residual media in dismounted pressure gauges can result in a risk to

persons, the environment and equipment. Take sucient precautionary

measures.

9. Disposal

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-

specic waste disposal regulations.
