12.3.3 Descaling and cleaning the tank
Scale and lime build-up prevent effective conduction of the heat to the water.
Periodic cleaning and descaling prevents build-up of these deposits. This
increases the service life of the water heater, and also improves the heating
process.
Take the rate of scale formation into account when deciding on the service
interval. Scale formation depends on the local water composition, the water
consumption and the water temperature setting. A water temperature setting of
maximum 60°C is recommended for the prevention of excessive scale build-up.
To guarantee a good, watertight seal around the cleaning opening, replace the
gasket (6), the O-ring (7), washers (4), bolts (3) and if necessary the lid (5) with
new parts before reassembly (see diagram). A special set is obtainable from the
supplier/manufacturer.
To simplify descaling and cleaning of the tank, the appliance is equipped with
two cleaning openings.
1. Remove the cover plate (1) on the outer jacket (see the figure).
2. Carefully remove the insulation (2) and set it to one side. This will be needed
again later.
