4. Operation
If the water level reaches the ON sensor
3
, the pump auto-
matically switches on. Depending on water volume and
environment, it can take 1 to 3 minutes until pumping out
commences. As soon as the water level falls below the OFF
sensor
4
, the pump is automatically switched off (the pump
continues to run for approx. 10 seconds).
1. Stand the pump on a firm surface
– or –
use a rope attached through the bore hole in the carrying
handle
5
to immerse the pump in a well or shaft.
2. Plug the power cable
6
into a mains socket.
The switch-on and switch-off height (see 8. Technical Data) can
be adjusted for automatic mode. The relevant sensor pin defines
the height of the water level.
