NOTICE
Malfunction due to changing the connection configuration
The pumping station connections are pre-configured at the factory. If the control lines on the connec-
tor are mixed up, this causes the pumping station to malfunction or fail.
► When removing components, note their original layout for subsequent re-assembly.
► Make a note of the accessories configuration and important setting values from the DCU before
disassembly of the pumping station or components.
