■ The sealing faces at the instrument have to be undamaged and
clean.
■ When screwing the instrument in, the force required to do this must
not be applied through the casing, but only through the spanner flats
provided for this purpose and using a suitable tool.
The correct torque depends on the dimensions of the process
connection and the gasket used (form/material).
Do not exceed the following tightening torque:
max. 30 Nm
■ When screwing in, do not cross the threads.
