(displays, housing, for example) and seals.
3. Do not use high-pressure steam.
4. Observe the degree of protection of the device.

Cleaning agents can damage the surfaces!
Incorrect cleaning agents can damage the surfaces!

e.g. benzyl alcohol, methylene chloride, xylene, concentrated glycerol cleaners or
acetone.
13.1.2 Cleaning of surfaces in contact with the medium
Note the following for cleaning and sterilization in place (CIP/SIP):
• Use only cleaning agents to which the materials in contact with the medium are
sufficiently resistant.
• Observe the permitted maximum medium temperature.

Cleaning with pigs

It is essential to take the internal diameters of the measuring tube and process connection
into account when cleaning with pigs. All the dimensions and lengths of the measuring
instrument are provided in the separate "Technical Information" document.

Replacing seals

The measuring instrument seals (particularly aseptic molded seals) must be replaced
periodically.
The interval between changes depends on the frequency of the cleaning cycles, the
