Maintenance And Cleaning - AL-KO Sub 8000 Bedienungsanleitung

Take suitable measures, e.g. installation
of an alarm or a back-up pump, to ensure
that flooding will not occur if the pump
should malfunction.
Make sure that the pump does not run on
a blocked or closed pressure hose.
Pumping out any remaining
liquid
Before you can pump out any remaining liquid
below the cut-off (= STOP) level (see technical
data), you will have to operate the float switch
manually:
1. Unplug the electric cable.
2. Fix the float switch so that it remains in an
upright position.
3. Plug in the electric cable. The pump will
automatically switch on and pump out any
remaining liquid.
While pumping out remaining liquid, make
sure to keep the pump under observation
and turn it off by pulling the plug when the
liquid has been completely pumped out,
so that the pump does not suck air, as
this may damage your pump.
If the level of the remaining water drops
below 10/40 mm, the pump will suck in
air. Before using the pump again to drain
liquid, the air trapped in the pump will
have to be let out (see Setting up and
Operating the Pump).

Adjusting the cut-in and cut-off levels
The float switch cable is attached to the pump
housing. You can adjust the cut-in = START and
cut-off = STOP levels for operation by simply
changing the height of the switch as desired.
Recommended length of the float switch cable is
approx. 120 mm.
Switching off the Pump
1. To switch off the pump, just pull the plug of
the electric cable from the socket.
