Switching on the pump
NOTICE
à
Ensure that no pressure or vacuum is present in the lines
when switching on.
à
Switch the pump on with the power switch.
Switching off/decommissioning the pump
à
When transferring aggressive media, flush the pump be-
fore switching off to extend the service life of the di-
aphragm (see Chapter 9 Servicing [} 28]).
à
Switch the pump off with the power switch.
à
Establish normal atmospheric pressure in the lines (re-
lieve pump pneumatically).
à
Pull out power plug of the pump.
The pump must not be started up
against pressure or vacuum during

brief power interruption during opera-
tion. If a pump starts up against pres-
sure or vacuum, the pump may block,
causing the thermal switch to respond
and the pump to switch off.
