Start-up
Attention! Sensitive electrical components.
Possible consequence: The unit will be destroyed.
Protective measure: Do not connect the unit to a dimmable power supply.
When started up, the pump automatically performs a pre-programmed self-test of approx. two minutes length (Envi-
ronmental Function Control (EFC)) . The pump detects if it is running dry / blocked or submerged. The pump
switches off automatically after approx. 90 seconds if it runs dry (is blocked). In the event of a malfunction, disconnect
the power supply and flood the pump or remove the obstacle. Following this, the unit can be restarted.
Switching on: Connect the unit to the mains. The unit switches on as soon as the power connection is established.
Switching off: Disconnect the unit from the mains.
