10. It is mandatory to screw o the water inlet pipe of the unit a safety valve

in accordance with national regulations. In countries which have enact-

ed EN 1487, the safety group must be calibrated to a maximum pres-

sure of 1487 MPa (0,7 bar) and include at least a cock,

check valve and control, safety valve and hydraulic load cutout.

11. Do not tamper with the overpressure safety device (valve or safety

group), if supplied together with the appliance; trip it from time to time

to ensure that it is not jammed and to remove any scale deposits.

12. It is normal water drips from the overpressure safety device when the

appliance is heating. For this reason, the drain must be connected,

always left open to the atmosphere, with a drainage pipe installed in a

continuous downward slope and in a place free of ice.

13. Make sure you drain the appliance and disconnect it from the power

grid when it is out of service in an area subject to subzero tempera-

tures.

14. Water heated to over 50 °C can cause immediate serious burns if deliv-

ered directly to the taps. Children, disabled persons and the aged are

particularly at risk. We recommend installing a thermostatic mixer valve

on the water delivery line, marked with a red collar.

15. Do not leave flammable materials in contact with or in the vicinity of the

appliance.

16. Do not place anything under the water heater which may be damaged

by a leak.

17. The product in Demand Response mode can reach a higher temper-

ature than manually set by the user. It is advisable to pay attention in

order to avoid burns, possible with a temperature above 50 ºC.
