General safety instructions

CAUTION Burns
During operation, the tap can reach temperatures in ex-
cess of 60 °C.
There is a risk of scalding at outlet temperatures in ex-
cess of 43 °C.
WARNING Injury
!
The appliance may be used by children over 3 years of
age and persons with reduced physical, sensory or men-
tal capabilities or a lack of experience and expertise,
provided that they are supervised or they have been
instructed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Cleaning and user maintenance must
not be carried out by children without supervision.
Material losses
!
The user should protect the appliance and its tap against
frost.

See type plate on the appliance.
3. Appliance description
The hydraulically controlled instantaneous water heater heats the
water as it flows through the appliance. When a tap is opened, the
appliance starts heating automatically at the selected output as
soon as the starting flow rate is exceeded (see chapter "Installa-
tion / Specification / Data table"). You can adjust the DHW amount
and temperature at the tap by mixing in cold water.
You can choose between 2 output stages. At stage 2, the hydraulic
control system regulates the electrical output automatically in two
output stages, subject to the flow rate.
The flow meter compensates for pressure fluctuations. The flow
meter ensures largely stable temperatures. The control unit limits
the flow rate, thereby ensuring an adequate increase in the DHW
temperature at all times.
Heating system
The tubular heater heating system has a pressure-tested copper
cylinder. The heating system is suitable for soft water areas (for
application range, see chapter "Installation / Specification / Data
table").

Settings

1
1 Partial output:
This setting is suitable for hand washing at a basin, for ex-
ample. At low flow rates, the appliance starts heating at half
the selected output.
2 Full output:
This setting is suitable for showers and washing up, for ex-
ample. At low flow rates, the appliance starts heating at half
the selected output and at higher flow rates, the full selected
output.
f Click the output selector into the required position.
For starting flow rates, see chapter "Specification / Data table /
ON".

Recommended tap/valve settings

Note
If the outlet temperature is not high enough when the
draw-off valve is fully open at full output, then more
water is flowing through the appliance than can be heat-
ed by the heating system (appliance is at its output limit).
f Reduce the water volume at the draw-off valve.
Low draw-off rate = high outlet temperature
High draw-off rate = low outlet temperature

f Turn the tap lever to the highest temperature.
f Fully open the tap.
f Increase the outlet temperature by closing the tap slowly.
f Reduce the outlet temperature by adding cold water or open-
ing the tap further, if possible.
