2. Safety
2.1 Intended use
This appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in a non-do-
mestic environment, e.g. in a small business, as long as it is used
in the same way.
This pressure appliance is designed to heat DHW. The appliance
can supply one or more draw-off points.
Any other use beyond that described shall be deemed inappropri-
ate. Observation of these instructions and of 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 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 aged8 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.
!
Material losses
Protect the appliance and its tap against frost.
2.3 CE designation
The CE designation shows that the appliance meets all essential
requirements according to the:
- Low Voltage Directive
- Electromagnetic Compatibility Directive
-
The maximum permissible mains impedance is indicated in
chapter "Specification".
2.4 Test symbols
See type plate on the appliance
Information for Australia/New Zealand:
Installation complies with standard AS/NZS 3500.4.
3. Appliance description
The hydraulically controlled instantaneous water heater heats
water as it flows through the appliance. When a tap is opened,
the heating output starts automatically as soon as the start-up vol-
ume has been exceeded (see chapter "Specification / Data table").
Adjust the DHW flow rate and temperature by mixing it with cold
water at the tap.
You can choose between 2 output stages. In addition, 2 output
stages are controlled hydraulically depending on the flow rate.
The flow rate controller compensates for pressure fluctuations,
thereby ensuring largely stable temperatures. The controller limits
the throughput, 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 "Specification / Data table").
4. Settings
D0000042703
1 2
1 Low power
This setting is suitable, for example, for washing your hands.
At low flow rates, half the heating output is applied.
2 Full power
This setting is suitable, for example, for baths, showers and
washing up. At low flow rates, half the heating output is ap-
plied; at higher flow rates, the full heating output.
Switch the output selector to the required position.
For start volumes, see chapter "Specification/ Data table/ On".
