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 children or persons with limited physical, sensory
or mental capabilities use the appliance, a permanent
and unchangeable temperature limit is necessary. Ask
a qualified contractor to set the internal anti-scalding
protection.
CAUTION Burns
If operating with preheated water, e.g. if using a solar
thermal system, observe the following information:
The DHW temperature may exceed the set temperature
or a set temperature limit.
f
In this case, limit the temperature with an upstream
central thermostatic valve.
!
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. 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.
Note
In order to comply with protection rating IP 25, coun-
tersunk screws must be used to secure the appliance to
the wall.
2.3 Test symbols
See type plate on the appliance.
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 set tempera-
ture is adjustable. Upwards of a certain flow rate, the control unit
selects the required heating output, subject to the temperature
selected and the cold water temperature.
The compact instantaneous water heater with electronic control
and automatic output matching maintains a consistent outlet
temperature. 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 set temperature, the water is not heated
further.
Heating system
The bare wire heating system is enclosed within a pressure-tested
plastic jacket. The heating system with its stainless steel heater
spiral is suitable for hard and soft water areas and is largely in-
susceptible to scale build-up. The heating system ensures rapid
and efficient DHW provision.
