INSTALLATION
Before proceeding to the operations of installation, maintenance and reparation of
the machine, read the manual carefully, where there is contained the necessary
information for the correct use of the machine.
Install the machine in a dry and not dusty place.
Put to level the machine through the regulation of the feet.
ELECTRIC CONNECTION
Before connecting the machine to the power, follow the following instructions:
o check that the electric line has a suitable course for the absorbed power
(1600W)
o check that the voltage corresponds to the data indicated in the plate on the left
side of the machine.
o The power has to have the efficient earth connection..
o In case of substitution of the cable of feeding, use only original cables (ask to
the manufacturer the special cable with type M connection)
The manufacturer will not take on any responsibility if these instruc-
tions are not respected.
All the electric devices in the machine work with a 24Vdc produced by the transformer except the boiler heating element and the same transformer, that use a tension of 230Vac or 120Vac on request.
The main light switch is a bipolar type and it supplies all the machine.
There are two fuses, 2A and 12A, which respectively protect the transformer and
the circuit in low voltage 24Vdc.
In case you have to extract the breakdown fuses, unscrew the hood container.
The 20Vac low-power circuit is interrupted by a safety button, situated on the
chassis, that cuts the current to the electronic board when the door is open.
Extracting the button, it is possible to reestablish the feeding with the door open
(by only technical staff).

TROUBLESHOOTING GUIDE
The machine is provided with a program of self-diagnosis, that allows to visualize
on the display the messages of breakdown or machine stopped :
Message
ERR. CUP-RELEAS.
ERROR ARM 0
ERROR ARM 1
ERROR ARM 2
ERROR GROUP 1
ERROR GROUP 0
Description
during the cup-releasing, the board has not
received the change of state of the cup-releaser
micro switch.
The electronic board has not received the “sugar
position” of the cup -arm signal by the relative
sensor on the cup-station board.
The electronic board has not received the “cup
position” of the cup -arm signal by the relative
sensor on the cup-station board.
The electronic board has not received the
“supply position” of the cup -arm signal by the
relative sensor on the cup-station board.
the coffee-group has not reached the “supply
position” given by its right micro switch.
the coffee-group has not reached the “normal
position” given by its left micro switch.
Probable cause
Fuses, cup-releaser motor, cup-releaser micro
switch, electronic board.
Fuses, cup blocked in the cup-arm, cup-arm
motor, position sensor, electronic board.
Fuses, cup blocked in the cup-arm, cup-arm
motor, position sensor, electronic board.
Fuses, cup blocked in the cup-arm, cup-arm
motor, position sensor, electronic board.
Fuses, group right micro switch, group motor,
electronic board.
Fuses, group left micro switch, group motor,
electronic board.
HYDRAULIC CONNECTION
INSIDE TANK
The machine is already set for the inside tank working.
WATER SYSTEM CONNECTION (OPTIONAL)
• disconnect the silicon pipe, which comes from the tank, from the limestone
filter.
• connect the silicon pipe coming from the water resevoir to the filter.
• connect the connector with the two grey wires coming from the water reser-
voir to the connector with two grey wires of the machine.
• disconnect the wires of the float and connect the black and green wires com-
ing from the water reservoir to the black and green wires into the machine.
• check that the net-system pressure doesn't overcome the 2 bars, otherwise it is
necessary to install a pressure reductor.
• Connect the water inlet tube to the inlet electrovalve with a ¾ " fitting.
