The medium to be measured must not be heavily soiled or contain coarse particles.
The level switch is not suitable for crystallising media. If the measuring element comes into contact
with a crystallising medium, the measuring element must be pulled out and cleaned immediately (see
chapter 7.2 "Cleaning").
6.2 Mounting
Do not expose the measuring element to high mechanical loads.
■
Do not expose the float to any impact loads.
■
The sealing faces at the instrument always have to be clean.
■
Only ever screw in, or unscrew, the instrument via the spanner
■
flats. Never use the case as a working surface.
The correct torque depends on the dimensions of the pressure
■
connection and the gasket used (form/material).
When screwing in, do not cross the threads.
