5.1 Reverse Rinsing Water Drainage
1.
Direct Connection Connect drainage according to
EN 806-5 or to national standards
CAUTION!
Drainage connection must have a minimum cross
section 'A' as indicated in table below to prevent
overflow from the pipework.

When our drain connector is used, the free 20 mm
discharge dimension required in EN 806-5 is integral
with the connector.

5.2 Setting of the Reverse Rinsing
Interval
EN 806-5 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 on the housing cover
Press pushbutton until the required programme
appears on display
Display indicates the number of completed reverse
rinsing cycles. This number can be reset by briefly
pressing pushbutton.
Service Indicator Displays
If programme pushbutton and reset pushbutton (for five
seconds) are pushed at the same time, the remaining time to
the next timed reverse rinsing cycle is indicated on and
display will indicate the corresponding time interval between
reverse rinsing cycles (0= minutes, 1 = hours and 2 = days).
After electrical power has failed, when it is restored a reverse
rinsing cycle will automatically occur. The set timed
programme and counter reading are retained. Counter can be
reset to 0 by pressing reset button.

Manual Actuation of the Reverse Rinsing
Reset - press pushbutton for five seconds
Manual Reverse Rinsing when Electrical
Power is off
Push the housing against the ball valve and towards the filter
and turn the housing 90° anticlockwise. After approximately
15 seconds return the housing to the original outlet position.

Additional connection options
6.1 Remote switching
The Z11AS can be remotely actuated by:
a)
A volt-free switching circuit
b)
Via an open-collector output.
In both cases the minimum 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 10 V 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 5 V 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 DDS76 differential pressure switch with
voltage free switching. It is recommended that the differential
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".
CAUTION!
The DDS76 differential pressure switch can only be
used where F76 / F76S / F76S-F fine filters are also
installed.
