Operation
Automatic operation
After the appliance has been connected to the mains power supply, it is
switched on and off automatically by the float switch:
• The pump begins to deliver when the float switch is lifted up by the liquid (1).
• The pump switches off when the float switch has sunk to the bottom (2).
The cable for the float switch can be adjusted in the cable holder (3). The dis-
tance between cut-in and cut-off point is adjusted in this way:
• Short cable: Cut-in and cut-off points are very close together.
• Long cable: Cut-in and cut-off points are very far apart.
Manual operation
– Attach the float switch in such a way that it points vertically upwards.
• The pump remains switched on irrespective of the water level.

of the contained metal balls.
