General safety instructions

WARNING Burns
During operation, the tap/valve and safety assembly can
reach temperatures in excess 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 aged 8 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 resulting risks. Children must never play
with the appliance. Children must never clean the ap-
pliance or perform user maintenance unless they are
supervised.
Material losses
!
The user should protect the water lines and the safety
assembly against frost.
Note
The appliance is pressurised. During the heat-up process,
expansion water will drip from the safety valve.
f If water continues to drip when heating is complet- f
ed, please inform your qualified contractor.

3. Appliance description
The appliance electrically heats up domestic hot water with the
standard heating output or with rapid heating. You can adjust
the temperature using the temperature selector. Subject to the
power supply, the water is automatically heated to the required
temperature.
You can use the appliance in single circuit, dual circuit or instan-
taneous water cylinder mode.
The internal steel cylinder is coated in "anticor
equipped with a protective anode. The anode protects the internal
cylinder from corrosion.

Frost protection
In single circuit and instantaneous water cylinder mode, the ap-
pliance is also protected against frost on the temperature setting
"cold", as long as the power supply is guaranteed. The appliance
switches on in good time and heats the water. The appliance does
not protect the water supply lines and the safety assembly against
frost. In dual-circuit operation, frost protection is only available
during off-peak tariff periods.
Instantaneous water cylinder mode
In this operating mode, the appliance works with normal heating
output when drawing off small amounts of water.
At high temperature settings and after large amounts of water
have been drawn off, the appliance automatically switches over
to booster heater (see chapter "Specification / Data table").
After the full amount of heated water in the cylinder has been
drawn off, the appliance works in instantaneous mode with a
booster heater. The available amounts of water that can be drawn
off are reduced accordingly (see chapter "Specification / Output
tables").
Following a longer power failure, the zero volt relay prevents the
booster heater from being switched on straight away. Once the
voltage returns, the appliance initially works with normal heating
output until the temperature controller reacts for the first time.
Subsequently, rapid heating is automatically ready for operation
again.
Dual circuit operation
During off-peak tariff periods (power supply companies' cheap
rate periods), the appliance automatically heats up the water
content with standard heating output at all temperature settings.
In addition, you can start the booster heater during peak tariff
periods.
Single circuit operation
In this operating mode, the appliance heats up the water automat-
ically subject to the connected heating output and temperature
setting.
