Switching ON/OFF
Switching on
The pump must be connected to the controller before the controller is switched on.
• First connect the controller to the mains supply, then switch on the pump at the controller.
Switching off
• Switch the pump off at the controller.
– Disconnect the controller from the mains before performing any work on the unit.
Environmental Function Control (EFC)
When started up and then every 20 ... 40 minutes the pump automatically performs a pre-pro-
grammed self-test (Environmental Function Control (EFC)). The pump detects if it is running dry
/ clogged or submerged. The pump shuts down automatically after 60 to 120 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.
