2. Safety
2.1 Intended use
The appliance is intended for installation in cylinders in a sealed unvented heating or DHW heating system.
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.
Using the appliance for heating fluids other than water or water supplemented with chemicals, such as brine, is also deemed in­appropriate.
2.2 General safety instructions
WARNING Electrocution Never spray the appliance with water or other liquids.
WARNING Burns There is a risk of scalding at outlet temperatures in ex­cess of 43 °C.
!
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
Condensate can drip from the appliance.
Never store objects below the appliance.
Note
The appliance is under pressure. During the heat-up process, expansion water will drip from the safety valve.
If water continues to drip when heating is complet-
ed, please inform your heating 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

3. Appliance description
The appliance electrically heats DHW and heating water.The temperature of the water is set by a qualified contractor via the temperature selector. Once the selected temperature has been reached, the appliance switches off and restarts automatically when required.
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 tap and the mains water supply line are not protected against frost by the appliance.

4. Settings
The temperature can be freely selected by the qualified contractor (see chapter "Installation / Settings").
Factory setting: 60°C
5. Cleaning, care and maintenance
Have the electrical safety of the appliance regularly checked
by an electrician.
Scaling
Almost every type of water will deposit lime at high tempera-
tures. Limescale will settle inside the appliance and affect its function and service life. The heating elements must there­fore be descaled from time to time. A qualified contractor who is aware of 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 becom-
ing blocked e.g. by limescale deposits.
6. Troubleshooting
Fault Cause Remedy
The water does not heat up.
There is no power. Check the fuses/MCBs in
your fuse box.
The temperature is incor-
rectly adjusted.
Check the temperature setting.
The flow rate is low. The aerator in the taps or
shower heads is dirty or scaled-up.
Clean or descale the aerator or shower head.
Water drips from the safety assembly after heating has stopped.
The valve seat is con­taminated.
Depressurise and isolate the appliance from the power supply. Request your qualified contractor to attend.
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):
