■ 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 case, 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 overwind the process connection, do not exceed the permissible torques.
■ When screwing in, do not cross the threads.
