CAUTION!
Warning against leaks
Feed chemical which remains in the overflow line at the
bleeder valve, can attack the valve or cause it to leak
– Route the overflow line with a continuous slope and
moreover with the tube nozzle pointed downwards - see

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.
