See type plate on the appliance.

3. Appliance description

The appliance electrically heats up domestic hot water with the standard heating output or with rapid heating. You can adjust the temperature using the temperature selector. Subject to the power supply, the water is automatically heated to the required temperature.You can use the appliance in single circuit, dual circuit or instan-taneous water cylinder mode.The internal steel cylinder is coated in "anticor " enamel and is equipped with a protective anode. The anode protects the internal cylinder from corrosion.Frost protectionIn single circuit and instantaneous water cylinder mode, the ap-pliance 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 appliance does not protect the water supply lines and the safety assembly against frost. In dual-circuit operation, frost protection is only available during off-peak tariff periods.Instantaneous water cylinder modeIn this operating mode, the appliance works with normal heating output when drawing off small amounts of water.At high temperature settings and after large amounts of water have been drawn off, the appliance automatically switches over to booster heater (see chapter "Specification/ Data table").After the full amount of heated water in the cylinder has been drawn off, the appliance works in instantaneous mode with a booster heater. The available amounts of water that can be drawn off are reduced accordingly (see chapter "Specification/ Output tables").Following a longer power failure, the zero volt relay prevents the booster heater from being switched on straight away. Once the voltage returns, the appliance initially works with normal heating output until the temperature controller reacts for the first time. Subsequently, rapid heating is automatically ready for operation again.Dual circuit operationDuring off-peak tariff periods (power supply companies’ cheap rate periods), the appliance automatically heats up the water content with standard heating output at all temperature settings. In addition, you can start the booster heater during peak tariff periods.Single circuit operationIn this operating mode, the appliance heats up the water automat-ically subject to the connected heating output and temperature setting.OPERATION Settings ENGLISH www.stiebel-eltron.com SHD | 19

The temperature can be freely adjusted. In single circuit and dual-circuit operation, the temperature setting can be limited by the qualified contractor (see chapter “Installa- tion/ Settings”).

Instantaneous water cylinder operation following a power failure Following a longer power failure, you can switch the booster heater on manually straight away by first turing the temperature selector to the "cold" position and then up to 85 °C.

5. Cleaning, care and maintenance

Have the electrical safety of the appliance and the function of the safety valve regularly checked by a qualified contractor. The protective anode must be replaced by a qualified con- tractor as soon as the SERVICE ANODE indicator illumi- nates (see chapter "Maintenance/ Replacing the protective anode"). Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance. Scaling Almost every type of water will deposit limescale 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 regularly. Limescale deposits at the tap out- lets can be removed using commercially available descaling agents. Regularly activate the safety valve to prevent it from becom- ing blocked, e.g. by limescale deposits.

Problem Cause Remedy The water does not heat up. There is no power. Check the fuses/ MCBs in your fuse box/distribu- tion panel. The flow rate is low.

The aerator in the tap or the shower head is scaled up or contami- nated. Clean and/or descale the aerator or shower head. SERVICE ANODE indicator illuminates. Replace the protective anode. Notify your qualified contractor. If you cannot remedy the fault, notify your contractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-000000): Nr.: 000000-0000-000000Made in GermanyD000004794220 | SHD www.stiebel-eltron.com INSTALLATION Safety INSTALLATION
