ELECTRICAL CONNECTION
The machine requires a single phase voltage of 230-240
V∿ and it is protected by a 15 A fuse.
For the connection, make sure that the plates data cor-
respond to the mains data, and in particular:
-The value of the voltage shall be within the recom-
mended limits;
-The general switch shall have suitable characteristics
for supporting the maximum load requested and it shall
ensure an omnipolar switch-off with a switch-contact
gap of at least 3 mm.
The switch, the socket and the plug shall be placed
in an accessible position.
The electrical safety of the machine is ensured only
when the machine is correctly connected to an efficient
earthing system, as foreseen by the current safety regu-
lations.
It is necessary to verify this fundamental safety
requirement and, in case of doubt, request an ac-
curate check of the system by qualified personnel.
The power supply cable has a non-separable plug. The
replacement of the connection cable (see Fig. 18) shall
be carried out only by qualified personnel and using
only cables of the type HO5 RN - F or HO5 V V-F or H07
RN-F 3x1-1.5 mm

cross section.
The use of adapters, multiple plugs and/or exten

sion cables is forbidden.
THE MANUFACTURER SHALL NOT BE HELD RE-
SPONSIBLE FOR ANY DAMAGE CAUSED BY THE
NON-OBSERVANCE OF THE ABOVE-MENTIONED
PRECAUTIONS.
FIRST START-UP
At the first start-up of the machine, it is necessary to fill
the hydraulic circuit (installation).
The filling procedure varies depending on whether the
machine obtains its water supply from a tank.

The display shows the message “water empty”
-Enter the “Engineer” programming mode and use the
special function “Manual installation” of the “Test” menu.
The machine performs an installation cycle
-When the installation cycle terminates, reset the fault

-Upon start-up, the mains solenoid valve is opened
automatically until the air-break is filled.
-The solenoid valve of the boiler opens to release the air
in the boiler and the hydraulic circuit.
-During the entire cycle, the display will show
“INSTALLATION”
N.B.: In case of a lack of water during the installa
-
tion cycle, the machine will stop to wait for water.
If substantial water pockets form in the hydraulic
circuit, then the hydraulic circuit must be filled us
