SAFETY
Safety
2.1 Intended use
The appliance is intended for installation in cylinders in a sealed 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 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 inappropri-ate.
Observation of these instructions is also part of the correct use of this
appliance. Any modifications or conversions to the appliance void all warranty
rights. It is also incorrect to use the appliance to heat liquids other than
water, or water containing chemicals such as brine.
2.2 General safety instructions
WARNUNG Electrocution Never spray the appliance with water or other
liquids.
WARNUNG Burns Bei Temperatur-Einstellung grdcr 43 °C kann sofort Wasser
hoher Temperatur fliegen.
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 result-ing risks.
Children must never play with the appliance. Children must never clean the
appliance or perform user maintenance unless they are supervised.
Note: While the threaded immersion heater is in use, the cyl-inder is
under mains water pressure. During the heating process, expansion water will
drip from the safety valve. If water continues to drip when heating is
completed, please inform your heating con-tractor.
2.3 Test symbols See type plate on the appliance.
**Equipment description
**
The appliance heats DHW electrically. You can adjust the tempera-ture using the temperature selector. Once the selected tempera-ture has been reached, the appliance switches off and restarts automatically when required.
Settings
The temperature is infinitely adjustable. Temperature selection is
limited at the factory and can be adjusted by the heating contractor (see
chapter “Installation / Settings”). You can interrupt the heating process by
setting the temperature selector to “cold” (see figure).
Cleaning, care and maintenance
- If the appliance is installed in a DHW heating system, please note that almost every type of water deposits limescale at high temperatures. Limescale builds up on the heating ele-ment in particular and has to be removed occasionally by the heating contractor.
- Always take the increased anode wear into consideration when using the threaded immersion heater in cylinders with protective magnesium anodes. Protective anodes and heat-ing elements should be checked after approx. one year.
- Regularly activate the safety valve to prevent it from becom-ing blocked e.g. by limescale deposits.
Troubleshooting
| Fault | Cause | Remedy |
|---|---|---|
| The water does not heat up. | There is no power. | Check the fuse/MCB in your |
fuse box/distribu- tion panel.
| The temperature is incor- rectly adjusted.| Check the temperature selection.
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):
INSTALLATION
7. Safety
Only qualified contractors should carry out installation, commis-sioning,
maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free operation and operational reliability only if the
original accessories and spare parts intended for the appliance are used.
7.2 Instructions, standards and regulations
Note: Observe all applicable national and regional regulations and
instructions.
7.3 Water connection and safety assembly
** Note Carry out all water connection and installation work in accordance
with regulations.
The cylinder must be connected with water inlet and outlet pipes made from
metal. Other metal parts of the cylinder that can be touched and that are in
contact with water must be permanently and reliably connected with the earth
conductor.
The max. permissible pressure must not be exceeded (see chapter “Specification
/ Data table” and cylinder specification).
► Install a type-tested safety valve in the cold water supply line. For this
bear in mind that, depending on the static pres-sure, 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.
8. Equipment description

► If you install the appliance in a cylinder with thermal insula-tion, use a
threaded immersion heater with extension. You can also use the extension to
reduce the immersion depth (see chapter “Specification / Data table”). The
maximum clearance between the threaded immersion heater and cylin-der (see
diagram) must not be exceeded.
Connecting the power supply
WARNUNG Electrocution Carry out all electrical connection and
installation work in accordance with relevant regulations.
WARNUNG Electrocution Make the power supply only as a permanent
connection. The appliance must be able to be separated from the mains power
supply by an isolator that disconnects all poles with at least 3 mm contact
separation.

Commissioning
Material losses
Boiling dry destroys the high limit safety cut-out and the controller-limiter
combination must then be replaced.
Material losses
If a heat exchanger is installed in the same cylinder, you must limit the
maximum temperature for this heat ex-changer. This prevents the high limit
safety cut-out of the threaded immersion heater from responding.
► Fill the system with water.
► Turn the temperature selector to maximum temperature.
► Switch the mains power ON.
► Check the function of the appliance.
► Check the function of the safety assembly.
10.1 Appliance handover
► Explain the appliance function to users and familiarise them with its
operation.
► Make users aware of potential dangers, especially the risk of scalding.
► Hand over these instructions.
11. Settings

selection limitation beneath the temperature selector. At the factory, the
appliance is limited to 60 °C.
► Isolate the appliance from the power supply.
► Set the temperature selector to “cold”.
► Pull off the temperature selector.
- Limiter disc
- Without limiter disc, maximum 80°C
► You can set the limit to 45°C / 60°C by rotating the limiter disc. By removing the limiter disc, the maximum temperature can be set.
► Replace the temperature selector.
12. Troubleshooting
Note: The high limit safety cut-out can respond at temperatures below -15
°C. The appliance may be subjected to these temperatures during storage or
transport.
| Fault | Cause | Remedy |
|---|---|---|
| The water does not lee up. | The high limit safety cut-out has responded | |
| because the controller is faulty. | Remedy the cause of the fault. Replace the |
controller-limiter com-bination.
| The high limit safety cut-out has responded because the temperature has
dropped below -15°C.| Press the reset button.
| The high limit safety cut-out has responded be-cause a heat exchanger In the
same cylinder is set too high.| Limit the maximum temperature of the heat
exchanger.
| The flanged immersion heater is faulty.| Replace the flanged im-mersion
heater.
The safety valve drips when the heating is ;witched off.| The valve seat is
con-taminated.| Clean the valve seat.
