Safety devices are not working or were removed.
•
Malfunctions have been detected on the valve.

Conversion Work
You should never make any technical modifications to the valve. Otherwise you will
have to undergo a new conformity process in accordance with the EC Machinery Direc-
tive on your own.
In general, only original spare parts supplied by GEA Tuchenhagen GmbH should be
fitted. This ensures the reliable and economical operation of the valve.
