Save energy and water
The water storage heater operates most economically when set to 55 °C. Scale builds
up more rapidly in the appliance at higher water temperatures and the heat loss is also
higher.
Reducing the water flow will help to save valuable drinking water.

Relief valve for pressure-type installation
• The relief valve of a pressure-type system must be vented slightly at regular inter-
vals (once per month) to ensure proper functioning.
• Turn the valve cap (V) anticlock-wise until the valve opens and water drains from the
outlet into the funnel. Reclose the valve. If this does not work, disconnect the appli-
ance and call a professional to examine the relief valve.
• If water constantly drips from the relief valve, it is probably soiled. In this case too, it
should be examined by a professional.
