CAUTION!
When connecting to an existing flange of another
make ensure that the inlet flow is through the outer
ring of holes. If this is not so, the whole connection
piece must be installed the other way round, even if
the arrow does not then indicate the actual flow
direction.
3. Install filter with sealing to rotatable connector
4. Tighten the connecting nuts (7Nm)
5. Screw in discharge connection
4.3 Discharge of reverse rinsing water
The reverse rinsing water must be routed to the drain channel
in such a way that no backwater can occur.
To do this there are 3 options:
• Direct connection:
• Connector DN 50/70 as well as the necessary
pipes and siphon (3 elbows 90°) in DN 70.
• Discharge into floor drain
• Drain into open container.

5.2 Reverse rinsing
During reverse rinsing, an inlet pressure of at least
1.5 bar is required.
The filter must be cleaned by reverse rinsing at the latest
every 6 months! (According to EN 806-5.) Producer
recommendation at least every 2 months!
To ensure convenient and regular adherence to the reverse
rinsing interval, we recommend installing an automated
reverse rinsing system.

CAUTION!
Filtered water can also be tapped during reverse
rinsing.
If reverse rinsing water is not to be discharged via a direct
connection, a collecting container must be positioned
beneath before reverse rinsing.
1. Open ball valve by turning the reverse rinsing handle
to the stop
• Handle must be upright
• The patented reverse rinsing system starts
2. Close ball valve again after approx. 3 seconds.
Repeat procedure three times
• If the filter is extremely dirty, the procedure may
have to be repeated additional times
With aid of the memory ring, the next deadline for
manual reverse rinsing can be booked.

Maintenance

In order to comply with EN 806-5, water fixtures must
be inspected and serviced on an annual basis.
As all maintenance work must be carried out by an
installation company, it is recommended that a
servicing contract should be taken out.
In accordance with EN 806-5, the following measures must
be taken:
