6 Maintenance
6.1 Maintenance safety instructions
Hazard due to toxic and harmful fumes, gases and substances (e. g. bacteria, viruses). If the pumping station
is located in a chamber, any necessary work must always be carried out by skilled personnel only (see 3.2).
Before opening housing covers, plugs and cables (including those on floating contacts) they must be safely
isolated from the power supply (de-energised). Work on electrical components may only be carried out by
skilled personnel (see 3.2).
If the floating contact is connected to an external device / connection, follow the manufacturer's operating
instructions for this device / connection.
Do not climb on electrical components, cable connections or cables during maintenance work.
Drowning hazard in the system chamber. In the event of a flood, a system chamber can fill with water within a
very short time. If there is a risk of penetrating water, the inspection chamber must not be entered until there
is no danger involved.
After all maintenance work, carry out a functional test on the pumping station (see 3.10.2).
6.2 Maintenance intervals
Note: A maintenance date can be set at the control unit. If the maintenance date has arrived, this is indicated by
a plain text message on the display.

maintenance following EN 12050). The intervals must not exceed:
- 3 months for systems in commercial use
