4 Maintenance

4.1 Maintenance

The instrument is maintenance-free. We recommend the following regular in-
spection to guarantee reliable operation and a long service life:

• Check the function in combination with downstream components.

• Check the leak-tightness of the pressure connection lines.

• Check the electrical connections.

The exact test cycles need to be adapted to the operating and environmental
conditions. In combination with other devices, the operating instructions for the
other devices also need to be observed.

4.2 Transport

The measuring device must be protected against impacts. It should be transpor-
ted in the original packaging or a suitable transport container.

4.3 Service

All defective or faulty devices should be sent directly to our repair department.
Please coordinate all shipments with our sales department.

 WARNING

Process media residues

Process media residues in and on dismantled devices can be a hazard to
people, animals and the environment. Take adequate preventive measures. If
required, the devices must be cleaned thoroughly.

Return the device in the original packaging or a suitable transport container.

4.4 Accessories

• M12 Connection lines of different lengths 

(see order code [

}

 16])

• Wall mounting set

4.5 Disposal

 WARNING

Incorrect disposal may pose a risk to the environment.

Please help to protect the environment by always disposing of the work pieces
and packaging materials in compliance with the valid national waste and recyc-
ling guidelines or reuse them.
