General information
SPECIAL INFORMATION
- 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, 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.
- The connection to the power supply is only per­missible as a permanent connection in conjunc­tion with the removable cable grommet. Ensure the appliance can be separated from the power supply by an isolator that disconnects all poles with at least 3mm contact separation.
- Observe the maximum permissible pressure (see chapter Installation/ Specification/ Data table).
- The appliance is pressurised. During the heat-up process, expansion water will drip from the safety valve.
- Regularly activate the safety valve to prevent it from becoming blocked, e.g. by limescale deposits.
- Drain the appliance as described in chap­ter „Installation/ Maintenance/ Draining the appliance“.
- Install a type-tested safety valve in the cold water supply line. Please note that, depending on the static pressure, you may also need a pressure re­ducing valve.
- Size the drain so that water can drain off unim­peded when the safety valve is fully opened.

2. Safety
2.1 Intended use
The appliance is intended for heating domestic hot water and can supply one or more draw-off points.
This appliance is designed for domestic use. It can be used safely by untrained persons. The appliance can also be used in a non­domestic environment, e.g. in a small business, as long as it is used in the same way.
Any other use beyond that described shall be deemed inappropri­ate. 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
WARNING Burns During operation, the tap and safety assembly can reach temperatures in excess of 60°C. There is a risk of scalding at outlet temperatures in ex­cess of 43°C.
Note
The appliance is under pressure. During the heat-up pro­cess, 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
The CE designation shows that the appliance meets all essential requirements according to the:
- Electromagnetic Compatibility Directive
- Low Voltage Directive
2.4 Test symbols
See type plate on the appliance.
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 pro­tects 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 automati­cally 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.
WARNING Injury
!
The appliance may be used by children aged 8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience 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 water lines and the safety assembly against frost.

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.

ON/OFF indicator
The ON/OFF indicator illuminates in single circuit and manual rapid heat-up operation while the water is heated, in dual circuit operation, it only illuminates during rapid heat-up.
Dual circuit operation with rapid heat-up
You can switch on rapid heat-up with the corresponding key. A remote control can also be installed for this purpose. The rapid heat-up function stops and will not restart when the selected temperature has been reached.
Manual rapid heat-up operation
You have to start the appliance with the rapid heat-up key. Once the selected temperature has been reached, the appliance switch­es off and does not restart.

5. Cleaning, care and maintenance
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Check the taps/valves regularly. You can remove limescale
deposits at the spouts using commercially available descaling agents.
Have the electrical safety of the appliance and the func-
tion of the safety assembly regularly checked by a qualified contractor.
The protective anode must be replaced by the qualified
contractor as soon as the SERVICE ANODE indicator illumi­nates (see chapter "Maintenance / Replacing the protective anode").
Heat content indicator
The currently available mixed water volume is displayed at 40°C with a cold water temperature of 15°C and a temperature setting of 65°C. The number of lights indicates the minimum available mixed water volume at 40°C.
This enables you to match the temperature setting to your draw-off pattern to ensure optimum efficiency and save energy. We recom­mend you set the temperature initially to 65°C. You can lower the set temperature if more than one indicator illuminates when your maximum draw-off volume is reached.
