Problem Cause Remedy
Water not flowing • Water supply interrupted • Open isolating valves fully
• Filter upstream of solenoid valve blocked • Clean or replace filter, see Cleaning or replacing filter
• Solenoid valve defective
• Replace, see Solenoid valve maintenance
• Plug-in connector of solenoid valve without contact • Attach plug-in connector
• Battery discharged
• Replace, see Battery maintenance
Indicator lamp • Battery almost discharged
• Replace, see Battery maintenance
flashing
Undesired flushing • The detection zone of the sensor system is
set too high
• An opposing object is detected. Reduce
detection zone using remote control (special
accessories 36 206).
Water flowing • Solenoid valve defective
• Replace, see Solenoid valve maintenance
continuously • piston blocked
• Clean piston, see Maintenance
Continuous running • Isolating valve not fully open
• Open isolating valves fully
/ persistent low • Nozzle blocked
• Clean piston, see Maintenance
water flow • Piston seal damaged
• Replace, see Maintenance
No flushing or • Leather seal dry or damaged
• Expand or replace
flushing too short • Flow volume set too low
• Adjust flow volume, see Setting flow volume
Flushing too long • Leather seal not yet saturated • trigger repeated flushing (approx. 5x) in order
to saturate seal
• Flow volume set too high
• Adjust flow volume, see Setting flow volume
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 if it is
necessary to make an alteration/adjustment to the factory
settings (Figs. 1 to 7)
1. Remove battery and replace after approx. 5 seconds
(Fig. 1).
2. Hold hand at a distance of approx. 5 to 10cm in
front of the sensor windows, LED flashes quickly
(Fig. 2).
3. The indicator lamp extinguishes automatically after
approx. 5 seconds (Fig. 3).
4. Remove hand from the detection zone (at least 60cm)
(Fig. 4).
5. Again hold hand at a distance of approx. 5 to 10cm in
front of the fitting (Fig. 5). LED starts to flash:
- 2 flashes (approx. 2 litres)
- Pause
- 3 flashes (approx. 3 litres = factory setting)
- Pause
- and so on until
- 7 flashes (approx. 7 litres)
6. Remove hand following a flashing sequence (desired
flow volume). The installation is then flushed with the
set flow volume. The selected flow volume is indicated
by the number of flashes (Fig. 6).
7. Checking the flow volume (Fig. 7):
- If the flow volume is ok, wait for > 20 s (fitting
automatically switches to normal operating mode),
then fit the cover.
- If not, set the flow volume again.
