Special accessories
• Infrared remote control (Prod. no. 36 206) for changing the
factory settings and selecting special functions.
Operation
The infrared electronics emit invisible, pulsed light. If this light
is reflected by a user for a minimum of 10 s (= minimum delay
time) and is then received again by the electronic system, the
solenoid valve is activated approx. 1 second after the user
moves away. The solenoid valve opens and the bowl is
flushed.
The range of sensitivity is dependent upon the reflective
properties of the object.

Installation
Plaster and tile the wall, excluding the area of the structural
shell protection.

Final installation

1. Cut off structural shell protection (A) flush with the wall,
see Fig. [1].
2. Open isolating valve (B) and flush pipe for at least 5 s,
then close isolating valve (B) again, see Fig. [2].
230 V AC
Switch off voltage supply!
1.8 VA
3. Fit upper part (C) of the transformer to base (D),
see Fig. [3a] or [3b], remove protection from contact
pins first.
45cm
4. Remove flushing aid (E) and screw in solenoid valve (F) by
2 l (factory setting)
hand, see Fig. [4].
Every 2 min (max. 14x)
5. Align frame (G) and fasten using screws (H), see Fig. [5].
6. Connect upper part (C) of the transformers and solenoid
valve (F) with electronics (J), see Fig. [6].
IP 55
7. Open isolating valve (B), see Fig. [2].
0.5 bar
8. Engage plate (K) at bottom of frame (G) and snap into
max. 10 bar
position at bottom by gently pushing upwards, see Fig. [7].
1 – 5 bar
9. Fasten plate (K) using locking screw (K1).

Setting mode
The flow volume can be checked and changed in setting mode
(see Setting the flow volume).
A
The detection zone of the fitting can be checked. The indicator
2
lamp in the sensor system of the fitting illuminates in setting
2500 V
mode when the detection zone of the fitting is reached by an
100 °C
approaching user.
Flushing is immediately triggered when the detection zone is
exited again. The minimum delay time of 10 s is not available
in setting mode.
To activate setting mode, proceed as follows:
1. Remove locking screw (K1), see Fig. [8].
2. Remove plate (K) upwards from frame (G).
3. Disconnect the power supply to the electronics and
reconnect after 5 s, see Fig. [9].
Setting mode is automatically terminated after 3 min.
Setting the flow volume
The factory-set flow volume is approx. 2 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 5 – 10cm in front of the fitting
sensor system.
The indicator lamp in the sensor system of the fitting flashes
quickly.
3. After approx. 5 s, the indicator lamp extinguishes
automatically.
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.
