SPECIAL INFORMATION
- 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 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.
- Use a permanent connection to the power supply. 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 "Specification/ Data table").
- The appliance is under pressure. During the heat­up 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 the 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.
- Fit the discharge pipe of the safety valve with a constant downward slope and in a room free from the risk of frost.
- The safety valve discharge aperture must remain open to the atmosphere.

Note
General information is identified by the symbol shown on the left.
Read these texts carefully.

This symbol indicates that you have to do something. The ac-
tion you need to take is described step by step.
2. Safety
2.1 Intended use
This pressure appliance is designed to heat DHW. This appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in a non-do­mestic 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. Any modifications or conversions to the appliance void all war­ranty rights.
2.2 General safety instructions
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 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.
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 qualified contractor.
2.3 Test symbols
See type plate on the appliance.
3. Appliance description
The appliance electrically heats domestic hot water, the temper­ature of which you can control with the temperature selector. Subject to the power supply, the water is automatically heated 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 “anticor
®
” enamel and is equipped with a protective anode. The anode with consumption indicator protects the cylinder in­terior from corrosion.
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.
3.1 Appliance type with single circuit operation
The appliance automatically heats up at any temperature setting subject to the availability of power.
3.2 Appliance type with 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 start the booster heater during peak tariff periods.

4. Settings
The temperature can be freely adjusted.
26�02�79� 0027
• Cold I Low temperature setting, 35°C II Recommended setting for energy saving,
low scaling, 60°C
III Maximum temperature setting, 85°C Depending on the system, the actual temperatures may vary from
the set value. In the delivered condition, temperature selection is limited. This
limitation can be cancelled by a qualified contractor (see chapter "Installation/ Settings").
4.2.1 Appliance type with dual circuit operation and quick heat-up function
The contractor needs to install a remote control to start the quick heat-up function. The rapid heat-up function stops and will not restart when the selected temperature has been reached.
5. Cleaning, care and maintenance
Have the electrical safety of the appliance and the function
of the safety assembly regularly checked by a qualified contractor.
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Signal anode with consumption indicator
!
Material losses
If the consumption indicator changes colour from white to red, have the signal anode checked by a heating con­tractor and if necessary replaced.

Scaling
Almost every type of water will deposit 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 spouts using commercially available descaling agents.
Regularly activate the safety valve to prevent it from becom-
ing blocked, e.g. by limescale deposits.
6. Troubleshooting
Problem Cause Remedy
The water does not heat up.
There is no power. Check the fuses/MCBs in
your fuse box.
The flow rate is low.
The aerator in the valve or the shower head is scaled up or contami­nated.
Clean and/or descale the aerator or shower head.
If you cannot remedy the fault, notify your qualified contractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-000000):
Nr.: 000000 - 0000 - 000000
