Appliance description

The appliance electrically heats domestic hot water, with the temperature controlled via the temperature selector. Subject to the power supply and operating mode, the water is heated automatically to the required temperature. You can use the appliance to supply one or several draw-off points.

The steel cylinder is coated on the inside with special directly applied enamel and is equipped with a thermometer and a protective anode. The anode with consumption indicator protects the cylinder interior from corrosion. The cylinder is enclosed by thermal insulation and a casing.
The appliance 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 water supply line and the safety assembly are not protected against frost by the appliance.

Single circuit operation
The appliance automatically heats up at any temperature setting subject to the availability of power.

Dual circuit operation
During off-peak tariff periods (cheap rate periods of power supply utilities), the appliance automatically heats up the water content with standard heating output at any temperature settings. In addition, you can switch on rapid heating during peak tariff periods.

Settings

The temperature is infinitely adjustable. Depending upon the system, the temperatures may vary from the set value.

1. Thermometer
2. Temperature selector
3. • Cold (frost protection)
4. I Low temperature setting, 35 °C
5. E Recommended energy saving position, low scaling, approx. 60 °C
6. III Maximum temperature setting, 82 °C

Temperature selection is limited in the delivered condition. This limitation can be cancelled by a qualified contractor (see chapter “Installation / Settings”).

Dual circuit operation with rapid heat-up function
You can switch on rapid heating with the pushbutton whenever necessary. Rapid heating stops and will not restart once the selected temperature has been reached.

1. Pushbutton for rapid heating

Cleaning, care and maintenance

• Have the electrical safety of the appliance and the function of the safety assembly regularly checked by a heating contractor.
• Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.

Signal anode with consumption indicator

Material damage
If the consumption indicator changes colour from white to red, have the signal anode checked by a heating contractor and if necessary replaced.

1. Signal anode with consumption indicator
2. White = anode OK
3. Red = ask your heating contractor to check

Scaling

Almost every type of water deposits lime at high temperatures.
This settles inside the appliance and affects both the performance and service life. The heating elements must therefore be descaled from time to time. A qualified contractor who knows the local water quality will tell you when the next service is due.

• Check the taps/valves regularly. You can remove limescale deposits at the tap outlets using commercially available descaling agents.
• Regularly activate the safety valve to prevent it from becoming blocked e.g. by limescale deposits.

Troubleshooting

If you cannot remedy the fault, notify your heating contractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (no. 000000-0000-000000):
