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.
