Operation (see page 9)
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 =
enabled, 2 x = disabled
Permanent rinse
After setting the parameters for the hygiene rinse or making a net reset, wait for
approx. 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 approx. 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.
