3.3 Temperature adjustment
Models with external thermal regulation are equipped with an adjustment knob situated onto the plastic
cap.The customer can adjust, as his preference, the temperature in order to get the best pleasure.We
suggest a regulation below the maximal set in order to achieve the best performance with o good level of
eciency and good comfort. Models with no thermostat control knobs have automatic water temperature
preset by the Manufacturer 65°C +/- 5°C

year. The operation can be carried out crumbling the limescale from the cover of the resistance. Take
care to not damage it.The magnesium anode must be substitute every 2 years (see warrantee condi-
tions). In order to remove it is necessary to remove the resistance. The pressure-relief device is to be
operated regularly to remove lime
deposits and to verify that it is not blocked.

models is necessary to overturn the appliance.
4.3 Bipolar safety reactivation
The appliance is equipped with a thermostat with safety limiting device according to IEC-EN regulations.
In case of abnormal overheating of the water, a thermal safety switch shuts off the electrical circuit on
both supplying phases of the heating elements; in this cases call the Technical Assistance to restart the
appliance.Resetting is manual. (fig.4-S/5-S).
5. USEFUL HINTS
• If hot water does not come out form the taps, before calling the Technical Assistance make sure that
the water and electrical connections are as specified in the relative paragraphs, or make sure of the
continuity of the phases between the clamps and the relative fastons on the thermostat, after taking it
off. If this is not, the bipolar safety device could have come into operation (call the Technical Assistance).
• If the warning lights does not light up, but hot water still comes from the appliance possibly it is only a
faulty bulb. For the replacement of the warning light bulb call the Technical Assistance.
