6. Operation
You can put the equipment into operation after
you have thoroughly read the installation and ope-
rating instructions. Pay attention to the following
points:
•
Make sure that the equipment is set up secu-
rely.
•
Check that the discharge line is fitted correct-
ly.
•
Make sure that the electrical connection is
220-240 V ~ 50 Hz.
•
Check that the electrical socket-outlet is in
good working order.
•
Make sure that no moisture or water can ever
reach the power connection.
•
Make sure that the equipment does not run
dry.
•
To switch off the equipment, pull the power
plug out of the socket outlet.
Note:
1. Lower the pump into the well or shaft by the
securing cable.
2. Ensure that the pump is at least 12 cm under
the surface of the water and approx. 30 cm
above the bottom.
3. Connect the mains plug to the socket.
The pump will start 3 seconds after the power
cable has been plugged in.
6.1 Automatic mode
The pump builds up pressure (e.g. the water tap
is closed) and then switches off automatically.
Thanks to the integrated non-return valve, the
pressure in the hose will be maintained until water
is removed again.
When the pressure drops below 2.5 bar, the
pump will switch on again automatically.
6.2 Dry-running protection
The pump will be switched off automatically when
there is no longer any water for pumping.
Now the pump will check for water in cycles of 10
seconds ON / 5 seconds OFF (2x).
In other words, the test cycle will be repeated af-
ter 1 hr, 5 hrs, 24 hrs, 24 hrs ....
As soon as the pump is immersed again in water
to a depth of at least 12cm, it will be ready for
operation again.
