15.3 Water-side 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 tank

.

3.

Cleaning condensation water discharge

.

15.3.2

Checking the anodes

Timely replacement of the anodes extends the service life of the appliance. 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 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 tank, the appliance is equipped with two cleaning openings.
