General safety instructions

CAUTION Burns
The tap can reach temperatures of up to 60 °C. There is a
risk of scalding at outlet temperatures in excess 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 up and
persons with reduced physical, sensory or mental capa-
bilities or a lack of experience and know-how, provided
that they are supervised or they have been instructed on
how to use the appliance safely and have understood
the resulting risks. Children must never play with the
appliance. Children must never clean the appliance 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. A qualified contractor can set the
limit for you.
Material losses

The electronically controlled instantaneous water heater with au-
tomatic output matching keeps the outlet temperature constant
up to the output limit. The temperature is then adjusted via the
draw-off tap.
DHW temperature
The DHW outlet temperature can be variably adjusted.
Internal temperature limit (qualified contractor)
On request, the qualified contractor can activate a permanent
temperature limit.
If supplying a shower, the qualified contractor must activate the
temperature limit.
Heating system
The bare wire heating system has a pressure-tested plastic cas-
ing. The heating system is suitable for hard and soft water areas
and is largely insusceptible to scale build-up. This heating system
ensures rapid and efficient DHW availability.

f Turn the temperature selector to the required position. f
If the outlet temperature fails to reach the required level with the
tap fully open and the temperature selector set to maximum, then
more water is flowing through the appliance than can be heated
by the heating element.
f Reduce the flow rate at the tap. f
4.1
Your instantaneous water heater offers maximum precision and
maximum convenience in DHW provision. Should you nonetheless
be operating the appliance with a thermostatic valve, we recom-
mend that you:
