3. Appliance description

The open vented (non-pressurised) appliance constantly maintains the water content at the pre-selected temperature. During heating, expansion water drips from the tap. The appliance may only be installed with taps for open vented (non-pressurised) water heat- ers (see chapter “Installation/ Appliance description/ Required accessories”).

You can set any required DHW outlet temperature at the tem- perature selector. The heat-up indicator illuminates during the heat-up process.

1 Heat-up indicator 2 Temperature selector Depending on the system, the actual temperatures may vary from the set value. °C = Cold. On this setting, the appliance is protected from frost. The tap and the water line are not protected. E = Recommended energy saving setting (approx. 60°C), minor scaling 85 = Highest selectable temperature Note A qualified contractor can set a temperature limit on the appliance (see chapter "Installation/ Settings/ Setting the temperature limit").

4. Cleaning, care and maintenance

Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance. Check the tap regularly. You can remove limescale deposits at the outlet using commercially available descaling agents. 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 should therefore be des- caled if necessary. A qualified contractor who is aware of the local water quality will tell you when the appliance should next be descaled.

Problem Cause RemedyThe appliance does not supply hot water. The temperature se-lector is set to “°C”. Switch the appliance ON by turning the temperature selector.

No power at the ap-pliance. Check the plug and the fuses/MCBs in the fuse box/distribution panel.Water can only be drawn at a reduced rate.The aerator in the tap is scaled up.Descale / replace the aer-ator.Loud boiling noises in-side the appliance. The appliance is scaled up. Have the appliance des-caled by a qualified con-tractor. If you cannot remedy the fault, notify your qualified contractor.
