6. Flow volumes and display:
The number of flashing signals of the consecutive groups
corresponds to the following flow volumes:
1 = flow volume 1 litres
Pause
2 = flow volume 2 litres
Pause
3 = flow volume 3 litres (factory setting)
Pause
...
7 = flow volume 7 litres
Pause
After the group with 7 flashing signals, the routine starts
from the beginning
1 = flow volume 1 litres
...
7. Selecting the flow volume
The flow volume is selected by removing the hand from the
detection zone (at least 60cm) in the pause after a group
of flashing signals. Once the hand is removed, the fitting
immediately flushes with the selected flow volume
(the corresponding flashing signals are displayed
again during flushing).
8. The flow volume can be readjusted within the next 20 s
if necessary by again holding the hand at a distance
of 5 - 10cm in front of the sensor system (see point 5).
The selected flow volume is accepted as the new setting and
setting mode is automatically terminated if there is no hand in
front of the sensor system 20 s after flushing. The area directly
in front of the sensor system must be kept free from objects for
these 20 s as otherwise the flow volume will be unintentionally
adjusted once more.
Maintenance
Inspect and clean all components and replace if necessary.
Shut off the water supply and switch off the voltage
supply.
Cleaning or replacing filter
1. Remove locking screw (E1), see Fig. [9].
2. Remove plate (E) upwards from frame (I), see Fig. [9].
3. Disconnect plug-in connector between solenoid valve (D)
and electronics (E), see Fig. [11].
4. Close isolating valve (H), see Fig. [12].
5. Remove solenoid valve (D), see Fig. [13].
6. Remove filter (K) and clean or replace, see Fig. [14].
7. Insert filter (K).
8. Fit solenoid valve (D), during this process pay attention to
the seals (D1) and the direction of flow, see Fig. [15].
9. Connect electronics (E) to solenoid valve (D), see Fig. [16].
10. Open isolating valve (H), see Fig. [7].
Assemble in reverse order.

Replacing the transformer
Switch off voltage supply!
1. Remove locking screw (E1), see Fig. [9].
2. Remove plate (E) upwards from frame (I), see Fig. [9].
3. Disconnect plug-in connector between transformer (F)
and electronics, see Fig. [17].
4. Pull headpart (F) of the transformer off the base (G),
see Fig. [17].
5. Attach new headpart, see Fig. [18].
6. Connect electronics and transformer (F), see Fig. [18].
Assemble in reverse order.
Replacing the top plate with electronics
1. Remove locking screw (E1), see Fig. [9].
2. Remove plate (E) upwards from frame (I), see Fig. [9].
3. Disconnect plug-in connectors from the electronics
module (E) to the solenoid valve (D) and to the
transformer (F), see Fig. [19].
4. Remove screws (E2) and holder (E3), see Fig. [20].
5. Replace old electronics module (E4) and assemble new
electronics module in reverse order on plate (E),
see Fig. [20].
6. Connect solenoid valve (D) and battery box (F)
to electronics (E), see Fig. [6].
Assemble in reverse order.
