The steps described here apply to all connections (input, output and bypass) equally.

on page 22 Pos. 1, 2, 3).
CAUTION!
Since the MFV is not an absolutely tight shut-of
f device, the bypass line
(vent line) must always be connected and led back into the dosing medium
tank!
In the case of dosing media which tend to crystallize, the overpressure
function cannot be guaranteed under certain circumstances.
It is not permitted to connect the bypass line to the suction line, otherwise
the venting function cannot be guaranteed.
The minimum cross section of the hose connections must be observed
accordingly (
Ä
Chapter 11.3 ‘Recommended minimum nominal diameter
for connecting lines’ on page 40), as otherwise the flow velocity and the
pressure conditions may increase inadmissibly. Translated with
