Approval and conformity
This product conforms to the requirements
of the relevant EU guidelines.
The conformity declarations can be obtained from the following
address:
GROHE Deutschland Vertriebs GmbH
Zur Porta 9
D-32457 Porta Westfalica
Special accessory (infrared remote control 36 206)
• The following settings can be made and changed with the
infrared remote control (Prod. no.: 36 206).
• Set reception range (20 - 60cm)
• Set flush duration (flow volume 1 - 7 l)
• Trigger flushing
• Switch off fitting
• Restore basic setting
• Test mode = waterless simulation
• Switch on/off 24-hour flush
• Switch on/off intermediate flush
• Switch on/off pre-flush
• Set minimum delay time

Operation

The infrared-electronic system emits invisible,
pulsed light. If this light is reflected by a user for
approx. 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
230 V AC
Plaster and tile the wall, excluding the area of the structural
shell protection.

Making settings

Setting mode
The flow volume can be checked and changed in setting mode
(see Setting the flow volume).
The detection zone of the fitting can be checked. The indicator
lamp in the sensor system of the fitting illuminates in setting
mode when the detection zone of the fitting is reached
by an approaching user.
It is possible to set the detection zone via the optional
remote control.
Flushing is immediately triggered when the detection zone
is exited again. The minimum delay time is not available
in setting mode.
To activate setting mode, proceed as follows: Disconnect
the power supply to the electronics and reconnect after 5 s,
see Fig. [10].
Setting mode is activated. Setting mode is automatically
terminated after 3 min.
Setting the flow volume
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).
