Safety Notes
Gloves should be worn during installation to prevent crushing and cutting
injuries.
Any work may only be carried out in a de-energized state. Here, the voltage
supply must be safely separated via the main switch or mains plugs.
Installation Instructions
• At the start of operation, or after maintenance, function of the faucet may be de-
layed due to reflections during adjustment of the operating distance. The faucet
will automatically calibrate itself. The self-calibration will start after 10-15 minutes.
• During initial start-up and after servicing, air in the fittings can cause an unattrac-
tive jet pattern. The jet pattern is okay again after switching the jet on and off
about 15 times.
Adjustment
This mixer has the following feature: background fade-out with integrated range
adjustment, that means the mixer is automatically adjusted on to the local condi-
tions (washbasin, brightness, reflection) by the sensory mechanism.
Battery operation
The indicator LED signals that the battery must be changed.
Battery voltage ≤ approx. 5.5 V: The indicator LED in the sensor window blinks
when the fitting is operated, water withdrawal continues to be possible
Battery voltage ≤ approx. 5.3 V: The indicator LED in the sensor window lights
continuously, water withdrawal is no longer possible, the battery must be replaced.
Attention! After insertion of the battery, the fitting should not be activated for ap-
prox. 30 seconds. This time is required for self-adjustment.
Replacement, installation and disposal of batteries is subject to the regulations speci-
fied in EN 60335-1 Appendix 3 Section 7.12.
Normal operation
The range of the detection area or the removal of the switch-on/off point from the
fittings depends on the ambient optical conditions (for example, the shape and
reflection of the washstand and the ambient light) as well as on the shape, the size,
the speed and the reflection of the object that was brought into the detection area.
The detection area of the fittings or the distance of the switch-on/off point from the
fittings is approx. 160 to 200 mm in normal operation.
The detection of dark (for example grey-black) objects by the fittings is inadequate
because of their low reflection. The range of the detection area or the distance
of the switch-on/off point can be smaller than 160 mm. The detection of bright or
reflecting objects by the fittings is very good as a result of their high reflectivity. The
range of the detection area or the distance of the switch-on/off point can be greater
than 200 mm. Strong light sources should not shine directly on the sensor window
of the fittings. Drops of water or condensed water on the sensor window of the fit-
tings can initiate unintended running of the water.
Range setting for infrared proximity electronics
It may be necessary to reduce the range of the infrared proximity electronics by
manual mode switching when the fittings are connected to very small or highly
reflecting washstands. The following two modes can be selected:
• "Maximum range" (factory setting)
• "Reduced range" (maximum range reduced by approx. 50 mm)
The LED behind the sensor window signals which mode the fittings are currently in:
• Short blinking when the fittings are closed = "reduced range"
• No blinking when the fittings are closed = "maximum range"
Perform the following steps to change from "maximum" to "reduced" range or vice
versa:
• Interrupt voltage supply of the fittings for approx. 10 s (disconnect electrical plug
connection between fittings and battery housing or power pack and reconnect
after 10 s)
• The LED blinks to indicate the software version (e.g. blinking once = software
version 1)
• When the LED lights permanently (-> calibration of infrared proximity electronics),
cover sensor window completely with your hand or a white piece of paper
• Remove your hand or the paper after 20 s to 40 s
• The LED indicates the currently activated mode by blinking: Once = "maximum
range", twice = "reduced range"
English
• The LED then lights permanently until the calibration of the just set range of the
infrared proximity switch has completed
• When the LED goes off again, the fittings are ready for operation
Cleaning washbasin (see page 34)
After setting the parameters for the hygiene rinse or making a net reset, wait for ap-
prox. 90 s before you can enable the "Clean wash basin" function.
Operation
(see page 34)
Hansgrohe recommends not to use as drinking water the first half litre flowing from
the tap in the morning, after the hygiene rinse is enabled, or after prolonged non-
use. The hygiene rinse opens the tap for 10 seconds every 24 hours following the
last operation.
Hygiene rinse
To enable or disable the hygiene rinse, proceed as follows:
• Interrupt voltage supply of the fittings for approx. 10 s (disconnect electrical plug
connection between fittings and battery housing or power pack and reconnect
after 10 s)
• The LED blinks to indicate the software version (e.g. blinking once = software
version 1)
• permanent light from the LED indicates that calibration of the infrared proximity
electronics is in progress
• wait for LED to go out
• cover sensor window completely with your hand or a white piece of paper
• Remove your hand or the paper after 10 s
• the currently enabled mode is indicated by the flashing of the LED: 1 x = ena-
bled, 2 x = disabled
Permanent rinse
After setting the parameters for the hygiene rinse or making a net reset, wait for ap-
prox. 90 s before you can enable the "Permanent rinse" function.
• cover sensor window completely with your hand or a white piece of paper
• The tap opens briefly and then closes immediately. When the tap opens again
after approx. 5 s, remove the hand or the paper from the sight glass.
• Permanent rinse is enabled for 180 s and can be interrupted at any time by a
movement in the field of vision.
Thermal disinfection
• Thermal disinfection pursuant to process sheet DVGW W 551(≥ 70°C / > 3 min)
must only be carried out by qualified personnel.
• Risk of scalding with thermal disinfection!
• The cold water feed must be locked during thermal disinfection. Afterwards,
"Permanent rinse" can be enabled.
Net reset
A net reset causes the fittings to re-adjust
• Interrupt the voltage supply to the fittings
• Briefly reach into the field of vision of the fittings to cause the capacitor to
discharge
• Wait for approx. 10 s, then plug the connectors in again
• The fittings will re-adjust during the next 30 s. Do not reach into the field of vision
during this period of time.
