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.
