The reverse rinsing water must be piped to
the drain in such a way that no back
pressure can occur.
To ensure this, there are three possibilities:
1. Direct connection to drainage pipework
A DN 50/70 reducing connector and
required DN 70 tundish and pipe
(maximum three 90º bends).
2. Free discharge into existing floor drain.
3. Discharge into an open container.

2. Reverse Rinsing

An inlet pressure of at least 1.5 bar is required
for reverse rinsing. The reverse rinsing interval
is dependent on the degree of contamination
of the water. DIN 1988, Part 8 requires that
the reverse rinsing interval shall be no longer
than every two months.
To ensure that convenient and regular reverse
rinsing takes place, we recommend that a
Z 11 S automatic reverse rinsing actuator be
fitted.
Water can still be drawn during the
reverse rinsing cycle
2.1 Manual Reverse Rinsing
If reverse rinsing is not via a direct drainage
connection, then a suitable container must
first be put underneath.
1. Open the ball valve by turning the
reverse rinse knob 1 until it reaches
stops
Indicator bar must be vertical
The patented reverse rinsing system
will start operating.
2. Close the ball valve after approximately
15 seconds.
A longer reverse rinsing period may be
necessary if the filter is very dirty.
The date of the next scheduled reverse rinsing
can be marked using the memory ring 2 .
2.2 Automatic Reverse Rinsing with
the Z 11 S
The Z 11 S automatic reverse rinsing actuator
is available as an accessory. The actuator
automatically controls reverse rinsing at any
preset interval between four minutes and
three months.
