maintenance
15.3.1
Introduction
The following steps must be carried out on the water side:
1.
Checking the anodes
.
2.
Descaling and cleaning the appliance and storage tank
.
3.
Cleaning condensation water discharge
.
15.3.2
Checking the anodes
Timely replacement of the anodes extends the service life of the appliance and
storage tank. The appliance's anodes must be replaced as soon as they are
60% or more consumed (take this into consideration when determining the
maintenance frequency).
1. Loosen the anodes using suitable tools.
2. Check the anodes, and if necessary, replace them.
15.3.3
Descaling and cleaning the appliance and storage tank
Scale and lime buildup prevent effective conduction of the heat to the water.
Periodic cleaning and descaling prevents buildup of these deposits. This
increases the service life of the appliance, and also improves the heating
process.
Take the rate of scale formation into account when deciding on maintenance
frequency. 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 prevention of excessive scale buildup.
To guarantee a good, watertight seal around the cleaning opening, replace the
gasket, washers, bolts and, if necessary, the lid with new parts before
reassembly (see the figure). A special set is obtainable from the
supplier/manufacturer.
To simplify descaling and cleaning of the appliance and storage tank, both are
equipped with a cleaning opening.
1. Remove the cover plate (1) on the outer jacket (see the figure).
2. Undo the bolts.
3. Remove the cover and the gasket.
4. Inspect the tank and remove the loose scale deposits and contamination.
