user could adapt the water storage temperature to the weather conditions and his particular needs.
The indications at regulation knob corresponds to the below approximate water temperatures inside the
tank:
Position '●': 7ºC. To avoid water freezing.
Position 'ECO': 55ºC approximately. Optimal temperature to reduce heat loses to environment and
reduce scales inside the appliance in hard water areas.
Position '+': 75ºC. Maximum water temperature inside the tank.

3.- LEGIONELLA THERMAL DISINFECTION CYCLE
In order to reduce the proliferation of Legionella inside the electric water heater, disinfection cycles should be carried out
with the recommended frequency in the following cases:
1) If the device is disconnected for more than a month, a disinfection cycle must be carried out when it is switched on.
2) If the water temperature is kept constantly below 55°C on a regular basis, a disinfection cycle should be carried out at
least every three months.
To carry out the aforementioned cycle, the temperature regulation knob must be placed in its maximum position (> 70ºC).
Once the aforementioned temperature has been reached, leave the adjustment knob in this position for 10 '. After this time,
the water heater can be adjusted to the desired temperature as usual.
WARNING!: When the thermal disinfection treatment has just been carried out, the temperature of the water in the water
heater can instantly cause severe burns. Children, disabled and the elderly are the people at highest risk for burns. Check the
water temperature before taking a bath or shower.
