N O T E
The unit will be destroyed if it is operated with a dimmer. It contains sensitive electrical components.
• Do not connect the unit to a dimmable power supply.
This is how to connect the power supply:
Switching on: Connect the unit to the mains. The unit switches on immediately.
Switching off: Disconnect the unit from the mains.
When started up, the pump automatically performs a pre-programmed self-test (Environmental Function Control
(EFC)). The pump detects if it is running dry / blocked or submerged. The pump switches off automatically after ap-
prox. 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. Afterwards, the unit can be restarted.
