Flow volume setting
The factory-set flow volume is approx. 3 litres at a flow
pressure of 3 bar.
The flow volume can be changed as follows:
1. Activate setting mode (see above).
2. Hold hand at a distance of approx. 5 - 10cm in front of
the sensor system in the fitting. The indicator lamp
in the sensor system of the fitting flashes quickly.
3. The indicator lamp extinguishes automatically after
approx. 5 s.
4. Remove hand from the detection zone (at least 60cm).
5. Again hold hand at a distance of approx. 5 - 10cm in
front of the sensor system. The flow volumes are
indicated via the indicator lamp in the sensor system
by groups of flashing signals separated by a pause.
6. Flow volumes and display:
The number of flashing signals of the consecutive
groups corresponds to the following flow volumes:
1 = flow volume 1 litre
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 litre
...
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 within 20 s of
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.
