Switching on the pump
In order to ensure that the pump starts every time, make sure
that counterpressure is reduced to an acceptable level before
start-up. This should also be done during operation after a brief
power cut. Please contact your local KNF partner for further in-
formation (www.knf.com).
Switching off the pump
KNF recommends: if transferring aggressive liquids, the pump
should be flushed thoroughly prior to switch off (see Section
8.2.1), as this will help to lengthen the service life of the dia-
phragm.
Restore the system to normal atmospheric pressure (release
hydraulic pressure in pump).

CAUTION
Overpressure on the suction side causes medi-
um to flow through the switched-off pump
Take steps to ensure that this cannot produce a
hazardous situation.
