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 distance 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.
