Protect the water lines and the safety assembly against
frost.
Note
The appliance is under pressure. During the heat-up pro-
cess, expansion water will drip from the outlet side of the
safety valve and/ or of the T&P valve. If water continues
to drip when heating is completed, please inform your
qualified contractor.
2.3 CE designation

3. Appliance description
The appliance heats domestic hot water electrically subject to the
connected heating output or with rapid heat-up. You can adjust
the temperature using the temperature selector. Subject to the
power supply, the water is heated automatically to the required
temperature. The currently available heat content is displayed.
The internal steel cylinder is coated with special directly applied
enamel and is equipped with a protective anode. The anode pro-
tects the internal cylinder from corrosion.
Dual circuit operation
During off-peak tariff periods (power supply utilities' enable
times), the appliance automatically heats up the water content
subject to the connected heating output and temperature setting.
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 automati-
cally subject to the connected heating output and temperature
setting.
Manual rapid heat-up operation
The appliance heats the water if the rapid heat-up button is
pressed. Once the selected temperature has been reached, the
appliance switches off and does not restart.
3.1 Frost protection
The appliance is also protected against frost on the temperature
setting "cold" subject to it being switched 'live'. The appliance
switches on in good time and heats the water. The water supply
lines and the safety assembly are not protected against frost by
the appliance. You can use the appliance in single circuit, dual
circuit or manual rapid heat-up operation.
