Health risk and potential environmental damage due to toxic contaminated parts or devices
Toxic process media result in contamination of the devices or parts thereof. During maintenance work
there is a health risk due to contact with these poisonous substances. The non-permitted disposal of
toxic substances results in environmental damage.

7.3 Removal of components for their maintenance
Maintenance work performed by the customer on the pumping station's components may require the
components to be removed from the pumping station frame.
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.
