ble use or failure to follow the instructions re-

ported in this publication.

3. Installation and maintenance must be per-

formed by professionally qualifi ed personnel

as specifi ed in the relative paragraphs. Only

use original spare parts. Failure to observe

the above instructions can compromise the

safety of the appliance and relieves the man-

ufacturer of any liability for the consequences.

4. DO NOT leave the packaging materials (sta-

ples, plastic bags, expanded polystyrene, etc.)

within the reach of children they can cause

9. 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

enacted EN 1487, the safety group must be

calibrated to a maximum pressure of 0,7 MPa

and include at least a cock, check valve and

control, safety valve and hydraulic load cut-

out.

10. Do not tamper with the overpressure safety

device (valve or safety group), if supplied to-

gether with the appliance; trip it from time to

time to ensure that it is not jammed and to re-

move any scale deposits.

11. 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 down-

ward slope and in a place free of ice.

12. Make sure you drain the appliance and dis-

connect it from the power grid when it is out

of service in an area subject to subzero tem-

peratures.

13. Water heated to over 50 °C can cause imme-

diate serious burns if delivered directly to the

taps. Children, disabled persons and the aged

are particularly at risk. We recommend install-

ing a thermostatic mixer valve on the water

delivery line, marked with a red collar.

14. Do not leave fl ammable materials in contact

with or in the vicinity of the appliance.

15. Do not place anything under the water heater

which may be damaged by a leak..

16. The water heating heat pump is supplied with

a sufficient amount of R134a or R513a refrig-

erant for its operation. This refrigerant fluid

does not damage the atmosphere's ozone

layer, is not flammable and does not cause ex-

plosions; however any maintenance activities

or work on the refrigerant circuit must only be

carried out by authorised personnel and with

the use of suitable equipment.
