5. MAINTENANCE INSTRUCTIONS (

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
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.
