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).
5.1

General maintenance information

Risk caused by toxic and hazardous vapours, gases and substances (e. g. bacteria, viruses). If the backwater
pumping 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 inspection chamber must not be entered until there is no
danger involved.
After all maintenance work, carry out a function test on the backwater pumping station.
5.2

Maintenance intervals

Maintenance of backwater pumping stations
The backwater pumping station must be maintained regularly by a technical specialist. The intervals must not
exceed 6 months.
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.
Device may not come into contact with mineral or partially mineral lubricants (such as WD-40). Mineral lubricants
can compromise the functionality of the product. Use fully synthetic lubricants only!
5.3
