modus to the Service position!

– Only tighten diaphragms by hand and do not use any tools!

– operating temperature
– and metering medium
We recommend that you check the diaphragm more frequently in extreme
operating conditions and if metering abrasive substances.
NOTICE!

ensure the leak-tightness of the system and secondly to ensure the integrity
of the thread.
The tightening torques of the metering head screws are given on an
