Operation
Switching the device on
Once you have completely installed the device as described in
the Start-up chapter, you can switch it on.
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
Info
The device has an automatic ventilation function. If the
liquid level is low, any air that is sucked in or that
remains in the pump will escape. In addition, liquids
may escape at this point.
If the device has trouble with the air intake when the
liquid level is low, you can repeatedly unplug and plug
in the mains plug to support the air suction process.
1. Plug the mains plug into a sufficiently fused mains socket.
ð
The device will be switched on when the float switch is
situated above the adjusted or the maximum switch-on
height.

The device will be switched off as soon as the float
switch reaches the set or the minimum switch-off
height.
Info
Once the device has been switched off, any water still
remaining in the line can flow back through the device.
