5. MAINTENANCE INSTRUCTIONS (qualified personnel only)
IMPORTANT: repair and/or maintenance operations must be carried only using original spare parts and by
qualified personnel. Before performing any maintenance operation, disconnect the appliance from the power
mains.
5.1. Safety limiting device (manual reset )
Reset, after eliminating the causes of intervention, as follows:
- disconnect the power supply;
- remove the protection cover fixing screws;
- lightly press the thermostat reset button, using an insulated object with round tip, in the position indicated in Fig. 1, until hearing a
click.
5.2. Control/Replacement of anode (only for versions with counterflange)
Its function is very important for protecting the tank against corrosion caused by stray currents or the aggressiveness of the water.
Anode wear is proportional to the protection work carried out and the quality of the water inside.
Make sure to check its efficiency at least every two years or in any case according to the quality of the water. Protection efficiency
is linked to its integrity. When checking, also check wear; replace if excessively worn or insufficient to guarantee protection until the
next foreseen control. Spare parts are available from the distributor and/or the manufacturer.
IMPORTANT: Remember that damage caused by excessive anode wear (insufficient tank protection) is not due
to manufacturing defects and is therefore not covered by the warranty.
5.3. Descaling (periodical).
To ensure good appliance efficiency it is advisable to periodically descale the heating element. The frequency of this operation
depends on the water hardness; proceed as follows:
- switch off the power to the appliance;
- empty the tank (see section on emptying the appliance);
- remove the electrical protection cover by undoing the fixing screws;
- disconnect the electrical wires from the respective terminals and remove the thermostat;
- remove the thermostat from its housing;
- remove the heating element with a suitable hexagon spanner;
- remove any scale and clean, taking care not to damage the heating element armour.

5.4. GENERAL NOTES

Use equipment suitable for the purpose.
Always replace the seal gaskets and/or O-rings.
Only use original spare parts.
When refitting, make sure:
- the heating element is correctly housed and that the seals are correctly fitted;
- the thermostat is inserted in the housing of the heating element, pushing it all the way in but without any striking that can damage it;
make sure the internal male/female contacts are correctly inserted;
- before reconnecting the power, fill the appliance (see the relevant section) and check for any water leaks.
