1. Installation
It is necessary during installation to
observe codes of good practice, to comply
with local requirements and to follow the
installation instruc-tions. The installation
location should be protected against frost
and be easily accessible.
2. Assembly
2.1 Close isolating valves 1 and 2 .
2.2 Open the ball valve on the filter by
turning the reverse rinsing knob.
The marker bar must be vertical.
Check availability of a suitable
drainage outlet or catchment vessel.
2.3 Pull off the reverse rinsing knob on the filter
2.4 Fit the automatic reverse rinsing
actuator with the bayonet connector
Plug in the Z 11 S
Push the housing in the direction of the
filter against the ball valve and at the
same time firmly restrain filter and turn
the housing through 90°.
2.5 Plug in the mains plug.
This will cause a reverse rinsing cycle
to occur.
3. Reverse Rinsing Water Drainage
3.1 Direct Connection
Connect drainage according to DIN 19886
or to national standards.
Drainage connection must have a
minimum cross section 'A' as indicated
in table below to prevent overflow from
the pipework.

DIN 1988 is integral with the connector.

4. Fitting Batteries and Fuses
The batteries provide a power supply to
close the ball valve in compliance with
regulations if the mains current fails during
the reverse rinsing cycle.
Batteries are not supplied with the
appliance.
4.1 Pull out the electrical mains plug
4.2 Unscrew the housing screws and
remove the lid.
4.3 Insert the batteries (Four LR 6 - 1.5 V -
Mignon/AA size alkali-manganese)
4.4 Change fuses if necessary
4.5 Reassemble in reverse order.
Do not leave the mains unplugged for
too long when batteries are fitted.
5. Setting of the Reverse
Rinsing Interval
DIN 1988 requires that a reverse rinsing
cycle must occur at intervals of not more
than two months. The time interval
should be set according to the level of
contamination present.
Setting of Other Intervals
Select required interval from the table 1
on the housing cover
Press pushbutton 2 until the required
programme appears on display 3
Display 5 indicates the number of
completed reverse rinsing cycles. This
number can be reset by briefly
pressing pushbutton 4 .
After electrical power has failed, when it is
restored a reverse rinsing cycle will automati-

mm
cally occur. The set timed programme and
counter reading are retained. Counter 5 can
be reset to 0 by pressing reset button 4 .
Manual Actuation of the Reverse Rinsing
Reset - press pushbutton 4 for five seconds

Service Indicator Displays
If programme pushbutton 2 and reset
pushbutton 4 (for five seconds)are pushed
at the same time, the remaining time to the
next timed reverse rinsing cycle is indicated
on 3 and display 5 will indicate the
corresponding time interval between reverse
rinsing cycles (0 = minutes, 1 = hours and
2 = days)
6. Additional connection
options
6.1 Remote switching
The Z 11 S can be remotely actuated by:
a)A volt-free switching circuit (e.g.
Honeywell Centra Bürkle type REL 2)
b)Via an open-collector output.
In both cases the minimium holding
period is one second. Reverse rinsing
occurs when the inputs "Start" and "U+"
have been separated.
6.2 Remote monitoring
For remote monitoring of the open/closed
position of the ball valve the installation of a
building management system with 0 to 10V
input is recommended. The maximum current
is 10 mA. With a current of 0.5 V the ball valve
is open and with a value between 5V and 6 V
the ball valve is closed.
6.3 Differential pressure switch
The reverse rinsing function can be actuated
according to demand using the DDS 76 dif-
ferential pressure switch with voltage free
switching. It is recommended that the diffe-
rential pressure be set to 1.0 bar. Operation
occurs when the inputs "Start" and "U+" have
been separated, that is, after the differential
pressure has fallen below the set value.
Through this it is guaranteed that a maximum
quantity of water is available for reverse
rinsing. If reverse rinsing starts immediately
irrespective of the duration of the differential
pressure signal, then the inputs should be
connected instead to "U+" and "SIGN" .
The DDS 76 differential pressure switch
can only be used where F 76 S fine
filters are also installed.

7. Safety Guidelines
7.1 Use appliance only:
In good condition
According to regulations
With due regard to safety
7.2 Follow installation instructions
7.3 Immediately rectify any malfunctions
which may influence safety.
7.4 The Z 11 S automatic reverse rinsing
actuator is exclusively for use in
reverse rinsing applications with
Honeywell Braukmann filters and filter
combinations. Any variation from this
or other use will not comply with
requirements.
All electrical work must be carried out
by authorised specialists and comply
with local regulations.
Materials containing solvents must not
be used for cleaning.
For safety reasons it is required that a
fuse be fitted to protect the electrical
junction box.
