5.2 Reverse rinsing
During reverse rinsing, an inlet (dynamic) pressure of at least
1.5 bar is required. The reverse rinsing interval depends on
the degree of dirt in the water. At the latest every 6 months,
reverse rinsing should be carried out according to EN 806-5.
Our 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 Z11S.
Filtered water can also be tapped during reverse
rinsing.
5.2.1 Manual 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 button
to the stop point
• Select bar 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.
5.2.2 Automatic reverse rinsing with the
Z11S
The automated reverse rinsing system Z11S is available as
an accessory. The automated system reliably takes over
reverse rinsing of the filter at intervals which can be set
between 4 minutes and 3 months.

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:
6.1 Inspection
6.1.1 Pressure reducing valve
1.
Close shut-off valve on outlet
2.
Check outlet pressure using a pressure meter when
there is zero through-flow
• If the pressure is increasing slowly, the valve may
be dirty or defective. In this instance, carry out
servicing and cleaning (See 6.2 Maintenance)
3.
Slowly open shut-off valve on outlet
6.1.2 Filter
•
The filter must be cleaned by reverse rinsing regularly,
at least every 6 months. (acc. to EN 806-5)
Our recommendation at least every 2 months!
•
Non-compliance can lead to the filter becoming
blocked This results in a drop in pressure and
decreased water flow
•
The filter meshes are made of stainless steel. A red
coating as a consequence of rust from the pipelines
has no influence on function or the way the filter works
CAUTION!
Do not forget to do a visual check of the ball valve.
Replace if it is dripping!
6.2 Maintenance
If necessary, the outside surface of the filter
combination can be cleaned.
Use only cold, clear drinking water to clean the
surfaces! Any other cleansers cause damage to the
plastic components!
6.2.1 Pressure reducing valve
1.
Close shut-off valve on inlet
2.
Release pressure on outlet side (e.g. through water
tap)
3.
Close shut-off valve on outlet
4.
Loosen slotted screw
• Do not remove slotted screw
CAUTION!
There is a spring in the spring bonnet. It may cause
injuries if the spring is derailing.
• Make sure tension in compression spring is
slackened!
5.
Slacken tension in compression spring
• Turn adjustment handle counter clockwise (-) until
it does not move any more
• Do not turn in too far!
6.
Unscrew spring bonnet
• Use double ring wrench ZR10K
7.
Remove slip ring
8.
Remove valve insert with a pair of pliers
9.
Unscrew filter bowl and guide piece
• Use double ring wrench ZR10K
10.
Remove old filter insert and replace by a new one!
11.
Remove slotted ring
12.
Place O-ring onto filter bowl
13.
Screw in filter bowl hand-tight (without tools)
