CAUTION!

Danger resulting from unnoticed diaphragm rupture

If the pump has been ordered with an electric diaphragm rup‐

ture sensor, it still has to be installed.

– Screw the enclosed diaphragm rupture sensor into the

liquid end (no seal necessary).

CAUTION!

Warning of unnoticed diaphragm rupture

Only above approximately 2 bar system back pressure is a

signal generated upon a diaphragm rupture.

– Only rely on the diaphragm rupture sensor at back pres‐

sures greater than 2 bar.
