2. Safety
2.1 Intended use
This appliance is suitable for heating domestic hot water or for
reheating preheated water. The appliance can supply one or more
draw-off points.
Water will not be reheated if the maximum inlet temperature for
reheating is exceeded.
The appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in non-do-
mestic environments, e.g. in small businesses, as long as it is
used in the same way.
Any other use beyond that described shall be deemed inappro-
priate. Observation of these instructions and of the instructions
for any accessories used is also part of the correct use of this
appliance.
2.2 General safety instructions
CAUTION Burns
During operation, the tap can reach temperatures up
to 70 °C.
There is a risk of scalding at outlet temperatures in ex-
cess of 43 °C.
CAUTION Burns
If operating with preheated water, e.g. from a solar ther-
mal system, the DHW temperature may vary from the
selected set temperature.
!
WARNING Injury
The appliance may be used by children aged 3 and older
and persons with reduced physical, sensory or mental
capabilities or a lack of experience and know-how, pro-
vided that they are supervised or they have been in-
structed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they are
supervised.
Where children or persons with limited physical, sensory or men-
tal abilities are allowed to use this appliance, we recommend a
permanent temperature limit. The following limitation options
are available:
- User adjustable: Temperature limit (e.g. for childproofing)
- Qualified contractor adjustable: Internal anti-scalding
protection

Material losses
The user should protect the appliance and its tap against
frost.
3. Appliance description
The appliance switches on automatically as soon as you open the
hot water valve on the tap. When you close the tap, the appliance
switches off again automatically.
The appliance heats water as it flows through it. The DHW outlet
temperature can be variably adjusted. From a certain flow rate,
the control unit regulates the correct heating output, subject to
the temperature selected and the current cold water temperature.
The electronically controlled instantaneous water heater with au-
tomatic output matching maintains a consistent outlet tempera-
ture. It is irrespective of the inlet temperature, up to the maximum
output of the appliance.
If the appliance is operated with preheated water and the inlet
temperature exceeds the selected set temperature, the word "hot"
and the inlet temperature are displayed alternately, and the "hot"
LED flashes. The water is not heated further.
You can save and quickly call up different temperatures. With
the ECO function, the flow rate is limited to 3 preset levels. The
appliance is equipped with functions to permanently limit the
temperature (e.g. for childproofing). The backlight switches on
automatically as soon as water starts to flow through the appli-
ance or you make a change on the user interface. The backlight
switches off automatically 5 seconds after water stops flowing or
if no operation has been performed for 30 seconds.
You can set the temperature unit and operating lock individually.
Heating system
The bare wire heating system is enclosed within a pressure-tested
plastic jacket. The heating system with its stainless steel internal
indirect coil is suitable for hard and soft water areas and is largely
insusceptible to scale build-up. The heating system ensures rapid
and efficient DHW provision.
