6 Maintenance
Before housing covers, plugs and cables (including those on potential-free contacts) are opened they must be
switched voltage-free. Work on electrical components may only be carried out by specialist staff (see 2.2).
6.1 General maintenance information
No climbing on electrical components, pipe connections or cables during maintenance work.
Risk caused by toxic and hazardous vapours, gases and substances (e. g. bacteria, viruses). If the backwater
lifting station is located in an inspection chamber, any necessary work must always be done by specialist staff
(see 2.2).
Risk of drowning 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 water entering, the chamber must not be entered until there is no danger
involved.
After all maintenance work, carry out a function test on the backwater lifting station (see 6.2.1).
6.2 Maintenance intervals
The maintenance date can be set in the menu 2. Maintenance / 2.4 Maintenance date (see control unit
instructions). When the maintenance date has arrived, this will be indicated by a plain text message on the
display.
Maintenance of lifting stations
The backwater lifting station must be maintained regularly by an appropriate expert. The intervals must not
exceed:
- 6 months for systems in commercial use
- 1 year for systems in private use
A maintenance protocol with details of all the work carried out and the main data must be prepared for all
maintenance work.
In as far as faults are found which cannot be eliminated, the system operator must be notified immediately in
writing by the maintenance expert, and must confirm receipt of this notification.
