8.2. Switching Pump/System on and off
Switching pump on
The pump may not start up against overpressure during
switch-on. This also applies in operation following a brief powe
failure. If a pump starts against pressure, it may block. This
activates the thermal switch, and the pump switches off.
Make sure that no pressure is present in the lines during
switch-on.
Switch on pump with mains switch (see fig. 2/19)
Switching off the pump/removing from operation
When transferring aggressive media, flush the pump prior to
switch-off to increase the service life of the diaphragm (see
chapter 9.2.1, page 37).
Switch off pump with mains switch (see fig. 2/19).
Open pressure and suction lines to normal atmospheric pres-
sure.
Disconnect the power source.
