POSSIBLE REPLACEMENT OF COMPONENTS
To work on the electronic board (Fig. 3, Rif. T), first disconnect the power cord from the outlet..
Remove it from its housing, as shown (Fig. 3), paying attention to the components that compose it, by
disconnecting the cable (Fig. 3, Rif. Y) from the card.
Use only original parts from authorized service centres authorized by the manufacturer.
PERIODICAL MAINTENANCE
To maintain good appliance efficiency, it is advisable to descale the heating element (Fig. 8, Rif. R) every
two years (frequency must be increased if the water is very hard).
If you do not want to use a liquid descaler (in this case, read the safety data sheets for the descaler),
simply break up the deposit, taking care not to damage the heating element coating.
The magnesium anode (Fig. 8, Rif. N) must be replaced every two years, otherwise the guarantee will
be invalidated. In the presence of aggressive water or water rich in chlorides, it is advisable to check
the state of the anode annually. To remove it, dismantle the heating element and unscrew it from the
support bracket.
Advice for user
- Avoid positioning any objects and/or appliances that could be damaged by water leaks beneath the
water heater.
- Should you not use any water for an extended period of time, you should:
• disconnect the appliance from the electrical supply by switching the external switch to ''OFF";
• turn off the plumbing circuit taps;
- Hot water at above 50°C flowing out of the taps at the point of use could cause serious scalds or even
death from burns. Children, the disabled and the elderly are more exposed to the risk of burns. It is
strictly forbidden for the user to perform any routine or extraordinary maintenance.
To clean the external parts use a damp cloth soaked in soap and water.
TEMPERATURE ADJUSTMENT AND FUNCTION ACTIVATIONS (Fig. 3)
To turn on the appliance, press the ON / OFF button ON/OFF " ", for at least one second.
When first switched on, the product is positioned at a temperature of 70°C. Set the desired temperature by
choosing a level between 40 ° C and 80 ° C, by pressing the "SET" button. After 3 seconds without any
action, the set point will be confirmed and stored. During the heating phase, the LEDs (40°C -> 80°C)
relating to the temperature reached by the water are steady on; the following ones, up to the set temper-
ature, flash progressively. If the temperature drops, for example as a result of a water withdrawal, the
heating is reactivated automatically and the LEDs between the last steady lit and the one relating to
the set temperature start flashing progressively again. In the event of a power failure, or if the product
is turned off using the ON/OFF " " button. The last set temperature is stored.
During the heating phase, a slight noise may occur due to the heating of the water.
ANTI-FREEZE FUNCTION
The anti-freeze function is the appliances automatic protection to avoid damages caused by very low tempe
ratures below 5 °C, in the event in which the product is turned off during winter. It is recommended that the
product remains plugged in to the mains power, even if iiis inactive for a long time.
Attention: the function is enabled, but it is not indicated in case of activation. Once the temperature rises to a
safer level such as to avoid damage from ice and frost, the water heating is switched off again.
ECO FUNCTION
The ECO function is activated by pressing the "SET" button until the ECO LED is on.
The ECO function aims to produce hot water by learning the user's habits. So, for the first week the
product stores the withdrawals and the timings in which these take place. From the following week water
heating is performed with respect to what the water heater has previously learnt.
