Operation
Hansgrohe recommends not to use as drinking water
the first quart flowing from the tap in the morning,
after the hygiene rinse is enabled, or after prolonged
non-use.
Hygiene rinse
The hygiene rinse turns the faucet on for 10 seconds
every 24 hours following the last use.
To enable or disable the hygiene rinse, proceed as
follows:
• Interrupt voltage supply of the fittings for approx.
10 s (disconnect electrical plug connection be-
tween 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 immedi-
ately. 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 (158°F) / > 3 min) must
only be carried out by qualified personnel.
• Risk of scalding with thermal disinfection!
• The cold water feed must be locked during ther-
mal 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.
