5
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.
Additional functions of the urinal fitting
The following settings can be made and changed with the
remote control (Prod. no.: 36 206):
Switch on/off 24-hour flush
(factory setting: switched on)
1. Press and hold the
RESET button.
2. Then additionally press the OFF AUTO button within 2 s.
The indicator lamp in the sensor system of the fitting flashes:
–
4 x short = 24-hour flush is switched on,
– 2 x long = 24-hour flush is switched off.
No-use flush interval: 24 hours.
Switch on/off intermediate flush
(factory setting: switched on)
1. Press the
TEST button => test mode is switched on.
2. Press the OFF AUTO button as required.
The indicator lamp in the sensor system of the fitting flashes:
–
4 x short = intermediate flush is switched on,
– 2 x long = intermediate flush is switched off.
Setting mode is quit by pressing the TEST button, or
automatically after 60 s.
Maintenance
Inspect and clean all components and replace if necessary.
