Appliance description

The closed (pressure-tested) appliance heats DHW electrically. You can adjust the temperature using the temperature selector. Subject to the power supply, the water is heated automatically to the required temperature.
The internal steel cylinder is coated with special “Co Pro” enamel and is equipped with a protective anode. The anode protects the internal cylinder from corrosion.

Frost protection
The appliance is also protected against frost by the temperature setting “*”, provided that the power supply is guaranteed. The appliance switches on in good time and heats the water. The ap-pliance does not protect the water supply lines and the safety valve from frost.

Settings

The temperature can be freely adjusted.

1. ON/OFF indicator
2. Temperature selector

• Frost protection
  E Recommended energy saving position, low scaling, 60 °C
  Max Maximum temperature setting, 80 °C
  Depending upon the system, the actual temperatures may vary from the set value.

ON/OFF indicator
The ON/OFF indicator illuminates when water is being heated.

Temperature indicator

1. Pointer position at approx. 30 °C
2. Pointer position at approx. 50 °C
3. Pointer position at approx. 80 °C

The current temperature is measured inside the cylinder, at the position of the temperature indicator (see chapter “Specification / Dimensions and connections”).

Holiday and absence

• If the appliance is not to be used for a few days, set the tem-perature selector to a position between the frost protection and energy saving settings.
• If the appliance is not to be used for a longer period, set it to frost protection to conserve energy. If there is no risk of frost you may disconnect the appliance from the power supply.
• For reasons of hygiene, heat up the content of the water heater once to above 60 °C before initial use.

Cleaning, care and maintenance

• Have the electrical safety of the appliance and the function of the safety valve regularly checked by a qualified contractor.
• Have the protective anode initially checked by a qualified contractor after the first year. The qualified contractor will then determine the intervals at which it must be checked thereafter.
• Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.

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 contrac-tor 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 becoming blocked e.g. by limescale deposits.

Troubleshooting

If you cannot remedy the fault, notify your qualified contractor. To facilitate and speed up your enquiry, please provide the numbers from the type plate (000000 and 0000-000000):
