corresponds to that of the power grid, and more specifically:
- the supply voltage rating must be within the range
recommended for the connection points;
1 - Connection terminal strip
2 - Cable clamp
3 - Power supply cable
The electrical safety of the machine is ensured only when
it is correctly earthed according to the safety standards in
force.
This fundamental safety requirement must be duly
verified, and if in doubt the system must be carefully
tested by qualified technicians.
- the main switch should be capable of withstanding the
peak load required, and at the same time ensure proper
omnipolar disconnection from the power grid with an
opening gap of the contacts of at least 3 mm.
The switch, the power outlet and the plug must be
located in an easily accessible position, so that the
cable can be disconnected in the event of intervention..
The power supply cable is of the type with a fixed plug. Any
replacement of the power cable (see Fig. 13) should be
made by qualified and suitably trained personnel only using
cables type HO5 RN - F or HO5 V V-F or H07 RN-F with a
3x1-1.5 mm2 section.

- the milk solenoid valve is opened so that the air may
be bled from the boiler and from the hydraulic system,
and 400 cc. of water filled.
N.B.:If there is no water flow from the mains during the installation
cycle, the machine will stop until water is resumed or the machine
is switched off.
IMPORTANT NOTICE!!!
If a considerable amount of air bubbles is formed in the
water system, for example during maintenance, it is possible that an installation cycle is automatically started when
the machine is switched on.
Versions with internal tank
For models with an internal tank, when the machine is
first switched on, the installation procedure MUST BE
carried out manually (see relevant chapter).
N.B.:When the machine is switched on for the first time or
in any case after initialising, as well as the list of controls
to be performed, also the language used for the messages
on the display is proposed.
The available languages can be scrolled with the “ ” and “ ”
buttons, and the selection is confirmed with button “ ”.
Unless the machine is initialised, the language request is

The dispensing valve opens, allowing the pump to push the
boiler water onto the coffee for the brewing cycle.
At the end of the dispensing cycle, the purge valve opens
and the coffee dose is lightly pressed, permitting the
discharge of residual water through the third way of the
dispensing solenoid valve. The purge solenoid valve opens,
depressurising the upper piston.
By completing the rotation of the ratiomotor (see Fig. 16) the
pistons and the coffee dose are lifted by means of the
swinging lever (6).
At the same time, when the brewing chamber returns to its
vertical position, the scraper on the coffee hopper stops the
used coffee dose and drops it.
The lower piston now returns to the top dead centre.
VARIABLE CHAMBER COFFEE UNIT
COFFEE DISPENSING CYCLE
When confirming the switch on cycle of the machine, by
pressing a selection button, the coffee unit is rotated
completely twice before the normal cycle, to ensure that the
device is in the correct start position.
When making a coffee based selection, the grinder will run
for the time necessary to fill the brewing chamber with the
coffee dose set via software.
When the ground coffee dose is reached, the ratiomotor
engaged with the handle (11) located outside the assembly
rotates by 180°, making the brew chamber swing (8) (see
Fig. 15).
The pump is started and, by effect of the water pressure, the
upper piston (5) is lowered enough to close the brewing
chamber and lightly compress the ground coffee.

CHECKING AND ADJUSTING
THE MACHINE SETTINGS
DECAFFEINATED DISPENSING CYCLE
The machine is supplied with a door, for manually inserting
ground coffee, locked by default.
According to the location needs, it is possible to
unlock the door to be able to manually insert decaffeinated
coffee or similar.
It is necessary to ensure that other product types are not
inserted.
The door for introducing the decaffeinated coffee is fitted
with a magnet that, through a sensor located on the door,
signals to the machine that the door was opened.
To get the best results from the product used, the following
should be checked:
That the used coffee dose is lightly compressed and
damp.
The grade of grinding of ground coffee.
The dose weight of the instant products.
The drink temperature.
The water dose.
Should the standard settings need to be changed, proceed
as indicated in the next sections of this manual.
The weight of products, the water dose and temperature are
directly controlled by the microprocessor.
To adjust them it is therefore necessary to follow the
programming procedures.
STANDARD SETTINGS
The vending machine is supplied with the following settings:
- coffee temperature (at the spout) approx. 70÷80° C;
- instant product temperature (at the spout) 70÷80°C
approx.;
The machine standard settings assign the same price to all
selections, as indicated in the selection dose table.

WATER TEMPERATURE CONTROL
ADJUSTING THE COFFEE DOSE
The boiler temperature is controlled by the software
and can be adjusted directly from the menu.
The grinder is fitted with a sensor that can count the number
of rotations of the grinding wheels.
This allows the control software of the machine to determine the number of rotations, and therefore grams of
coffee, for each single selection.
With the programming procedures it will be possible to set
the grams (5.5 to 11.5 g) of ground coffee for each selection.
To take the dose just remove the coffee unit and select the
special item from “Special functions” of the “Technician”
menu (see relevant section).
Important notice!!!
ADJUSTING THE GRADE OF GRINDING
When a variation in the grade of grinding is desired, turn the
relevant adjusting knob on the grinder (see Fig. 18) and
more specifically:
To refit the coffee unit, pay special attention to the
piston position.

- turn the knob anticlockwise for coarser grinding;
- turn the knob clockwise for finer grinding.
For optimum results, it is advisable to vary the grade of
grinding with the coffee grinder motor running.
N.B.: After adjustment of the grade of grinding, at least
3 test selections must be performed in order to check
the new grade of grinding for ground coffee:
The finer the grade of grinding the longer the time necessary
for dispensing the coffee and vice versa.
After the adjustment it will be necessary to check also the
amount of ground coffee, which can have small variations.

MAINTENANCE
Important notice!!
Access to the machine interior for maintenance and/or
repairs is via the back panel and from the side panels.
Therefore the machine is designed to be rotated, thus
allowing removal of the back panel and of the side panels.
The integrity of the machine and compliance with the
standards of the relevant systems must be checked at
least once a year by qualified personnel.
With the main switches turned off, the terminal strip
connected to the line cable, the fuses and the noise
suppressor stay energised in any case.
Before starting any maintenance operations requiring
parts of the unit to be removed, the machine must
always be switched off.
The operations described below must be carried out
only by personnel who have the specific knowledge of
the machine functioning from a point of view of electrical safety and health regulations.
INTRODUCTION
Fig. 21
To ensure correct operation for a long period, the machine
must be subjected to regular maintenance.
The following sections contain the procedures and the
maintenance schedule, which are only a general indication,
as they greatly depend on the operating conditions (e.g.
water hardness, environmental humidity and temperature,
type of product used, etc.).
The procedures described in this chapter are not exhaustive of all maintenance operations to be carried out.
More complex operations (e.g. boiler descaling) should be
carried out by qualified technicians only having specific
knowledge of the machine.
To prevent oxidation or the action of chemical agents, the
stainless steel and varnished surfaces should be kept
clean by using mild detergents (solvents must not be used).
Under no circumstances should water jets be used to
clean the machine.

AND FOODSTUFF CIRCUITS
When installing the machine, and then at least once a week
or even more frequently according to the use of the machine
and the quality of the inlet water, the mixers and the
dispensing conduits must be thoroughly sanitised (cleaned
and disinfected), to guarantee proper hygiene of the dispensed products.
The parts to be cleaned are as follows:
- powder deposit drawers, mixer and instant drink dispensing conduit;
- dispensing spouts;
- spout support tray;
- remove the powder and the water funnels, the feeders, the
powder deposit drawers and the mixer wheels from the
mixers (see Fig. 22);

- in order to remove the water funnel the green ring nut must
be rotated anticlockwise;
Wash all parts with detergent being sure that all visible
residue and product layers are mechanically removed,
using a brush if necessary.
pay special attention to closing it fully during
reassembly;
Disinfection should be carried out using sanitising products.
- soak all components for approx. 20 minutes in a container
filled with the previously prepared chlorine-based detergent;
- reinstall the feeders and the water funnels;
- reinstall the powder deposit drawers and the powder
funnels after thoroughly drying them.
After reinstalling all parts the following is however

PRINTED BOARD FUNCTIONS
AND INDICATOR LAMPS
ACTUATION BOARD
This board, placed at the back of the machine, (see Fig. 25)
processes the information from the push-button card and
from the payment system; it also controls the actuations,
the input signals and the boiler board.
The 15 V AC voltage required for board operation is supplied
by a transformer which is protected by a 125 mAT fuse on
the primary and by a 1.25 AT fuse on the secondary
winding. The voltage supply is rectified and stabilised
directly by the board.
This board houses the Flash EPROM. The control software
of the board is installed directly (via RS232 or UpKey) in the
microprocessor.
- the red LED (7) indicates the operating status of the boiler
heating element;
- the red LED (9) for resetting the CPU glows during the
board reset;
- the green LED (11) blinking indicates that the microprocessor is working correctly;
- the yellow LED (12) indicates the presence of 5 V DC.
