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.

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.
