N.B.: On the long run the water characteristics considerably affect the correct operation of the machine and
increase the need of maintenance, particularly regarding
the boiler and the dispensing solenoid set.
Run water from the mains until it is clear and without any
traces of impurities.
Use a hose capable of withstanding the water mains
pressure and suitable for use with foodstuffs (minimum
insidediameter of 8 mm) to connect the water supplyto the
314" gas-type union of the water inlet solenoid valve.
As an optional, a "water supply hose kit", composed of a
1.5 m hose and all necessary fittings, is available.
INSERTING THE PRODUCT LABELS
It is good practice to install a suitable cutoff valve on
the water supply outside the machine in an easily
accessible position.
The labels indicating the available product selections in
the current language shall be inserted into the special slots
following the procedure shown in Figure 2.
OVERFLOW DEVICE
INSTALLING THE TILTING GRATINGS
Tilting stainless steel gratings are supplied, used to support cups in alternative to jugs.
To facilitate positioning of the cups by the user, plastic
made, red colour markers are also supplied, to be inserted
in the gratings.
The water inlet solenoid valve (see Fig. 5) is fitted with an
overflow device which mechanically stops the water flow
when there is a malfunction to the valve or to the boiler
water level control device.
To restore normal operations, proceed as follows:
-Turn off the external main switch and disconnect the
electrical plug;
-
Drain the water contained in the overflow pipe;
- Shut off the water supply valve outside the machine;
Before installing the machine the same procedure planned
for the annual sanitising should be carried out (see relevant section) to eliminate any bacteria which may have
formed during storage.
-
Loosen the nut which secures the solenoid valve supply
hose to relieve the water mains residual pressure and
then tighten it again;
-Open the valve and switch on the machine.
CONNECTING THE MACHINE
TO THE WATER MAINS
The machine must be connected to the drinking water
mains. The water pressure must be O,O5 to 0,851MPa (0,58,5 bar).

CONNECTING THE POWER SUPPLY
The electrical connection, as indicated in the diagram of
Fig. 7, is made using the special plates housed in the
term~nalbox as jumpers.
The machine is designed to operate under single-phase
230 V- voltage and is protected by 15 A fuses on each
phase and on neutral.
Considering the power absorbed by the machine, it is
advisable to connect it to a three-phase 400 V 3N line; a
line with the following characteristics can be used for the
power connection:
- Three-phase + N
-
Single-phase

400 V- 50 Hz (recommended)
(see Fig. 6)
230 V- 50 Hz (see Fig. 6 and 7)
The machine is supplied without power cable; for connection to the power grid use only cables type H05 VV-F or
H05 VV H2-F with adequate section. Before making the
connection ensure that the ratings correspond to those of
the power grid, and more specifically that the supply
voltage rating is within the range recommended for the
connection points
A main switch, suitable for withstanding the required peak
load required, must be located within easy reach, and at
the same time must ensure proper omnipolar disconnection from the power grid with the opening gap of the
contacts of at least 3 mm.
Single-phase connection
230 V50 Hz
3 x 4 rnrn2cable

If the line is not suitable for withstanding a load of 7400 W,
it is possible to reduce the absorbed power to 3150 W, by
excluding one of the two heating elements in the instant
product boiler when making the electrical connection.
In this case the performance of the machine regarding hot
water output will be halved.
The electrical connection, as indicated in the diagram of
Fig. 8, is made using the special plate housed in the
terminal box as jumper.
The machine electrical connections must be permanent. Do not use adapters, multiple sockets and/or
extensions.
The electrical safety of the machine is ensured only
when it is correctly earthed according to the safety
regulations in force.
This fundamental safety requirement must be duly verified, and if in doubt the system must be carefully tested by
qualified technicians.
The power cable must be connected to the specific terminal box located on the back panel of the machine, ensuring
correct position of the phases as indicated in the diagrams.

To carry out the machine setting and configuration operations it is sufficient to insert the special key into the slot (see
Fig. 1).
The door can be closed only after removing the key from
door switch.
However, it is possible to make simple changes to the
preset machine configuration by appropriately rearranging the piping and setting the minidip switches on the CPU
card differently (see the selection dose table), thus obtaining the "self service" version, i.e. preset for dispensing
drinks into cups from one single point (refer to Figure 9-B)
and with the pre-selection buttons disabled (see Figure 2).
The different options of each configuration can be modified
in the programming mode (refer to relevant section).
Also the disabled keys can be activated, regardless of the
selected configuration.
THE MANUFACTURER DECLINES ALL RESPONSIBILITY FOR ANY DAMAGE CAUSED BY THE NONCOMPLIANCE WITH THE ABOVE MENTIONED PRECAUTIONS.
FILLING THE WATER SYSTEM
Great care should be taken for the compatibility between the selection push-button configuration and
the piping layout.
For example, with the "hotellerie" configuration, the white
coffee selection can be enabled only if the whitener and
coffee pipes are fitted in the same position (Figure 9-A).
Before switching the machine on, ensure that it is correctly
connected to the water mains and that the check valve is
open.
If the air-break device indicates a water failure for more
than 10 seconds after switching the machine on, an
installation cycle will start automatically, and namely:
INSTANT PRODUCT DISPENSING CYCLES
- t h e message "Installation" will be shown on the display
for the entire duration of the cycle;
According to the type of product the dispensing cycles of
the different selections are designed to obtain the best
possible results concerning drink quality and output .
With the cup selection, the powder for chocolate-based
drinks is dispensed intermittently, whereas for instant
coffee-based drinks the powder is dispensed before the
water.
On the other hand, with the jug selection the powder is
dispensed intermittently for all types of drink; the correct
waterlpowderproportion is always maintained, even in the

the air from the boiler allowing it to be filled with 600 cc.
of water.
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.
-
This operation must be carried out manually after any
maintenance requiring the boilerto beemptied but not
the air-break, using key 1.
It is therefore important not to alter the flow rate of the
solenoid valves which is factory preset.
Only in the case of replacement or accidental tampering
with the solenoid valves, the flow regulators should be
adjusted to dispense 25 cclsec for chocolate and coffee,
20 cclsec for milk, and 30 cclsec for water.
CONFIGURING THE MACHINE
The vending machine is supplied as "hotellerie" version,
i.e. preset for dispensing more products in variable doses
at the same time (see Figure 9-A).
CLEANING CYCLES
A mixer cleaning cycle can be started either with the
special button on the push-button card (for qualified
personnel only), orwith button "A" on the external panel,
if enabled (see Figure 2). To prevent any unintentional
operations of the external cleaning button, this must be
pressed twice in ashort sequence and then a programmable 5-digit password should be entered. The default password is "55555".
During the cleaning cycle all mixers are operated at the
same time, and all solenoid valves are actuated intermittently. Such intermittent operation ensures easier removal
of the scaling.
The cleaning cycle can be interrupted with the "STOP"
button.

COFFEE DISPENSING CYCLE
When selecting coffee, the grinder is started and will
continue until the coffee dosing unit chamber is full (see
Figure 13).
When the dosing unit is full, the ground coffee dose is
released into the coffee unit.
The coffee is dropped into the vertical brew chamber (1)
(see Figure 10).
CHECKING AND ADJUSTING
THE MACHINE SETTINGS
To get the best resultsfrom the product used, the following
should be checked:
for coffee
That the used coffeedose is lightly compressed anddamp.
The grade of the ground coffee.
The weight of the ground coffee.
The dispensing temperature.
123456-
Brew chamber
External disk
Upper piston
Lower piston
Pre-brewing spring
Swinging lever
The water dose.
for instant products
The weight of the instant products.
The drink temperature.
Fig. 10
The water dose.
Should the standard settings be varied, proceed as indicated in the next paragraphs of this manual.
The weight of the instant products, the water dose and
temperature are directly controlled by the microprocessor.
To change them it is therefore necessary to follow the
programming procedures.
The gearmotor handle engaged with the disk (2) located
outside the assembly rotates by 180", swinging the brew
chamber and lowering the upperpiston (3) (see Figure 11).
STANDARD SETTINGS
The vending machine is supplied with the following standard settings:
- coffee temperature (at the spout) approx. 85-89°C;
-
Fig. 11
123456-
Brew chamber
External disk
Upper piston
Lower piston
Pre-brewing spring
Swinging lever
instant product temperature (at the spout) approx. 75°C.
The standard setting of the machine assigns the same
price, expressed in number of basiccoins, to all selections.
ADJUSTING THE SETTING OF THE
COFFEE UNIT PISTON STROKE
When the upper piston is correctly positioned, the coffee
unit can operate with coffee doses of 5.5 to 7.5 g.
To change the piston position (see Figure 12):
- remove the snap ring from its seat;
-
place the piston in the proper adjusting notches:
.less deep notches for 5.5 to 6.5 g. doses;
.deeper notches for 6.5 to 7.5 g. doses.
Due to the water pressure, the pre-brewing spring (5) sinks
and the lower piston (4) is lowered 4 mm, thus forming a
water cushion which allows an even use of the coffeedose.
At the end of the dispensing cycle and during a pause of 3
seconds, the pre-brewing spring (5) will discharge the
water through the third way of the dispensing valve, lightly
pressing the used coffee dose.
By completing its rotation, the gearmotor causes the
swinging lever (6) to lift the pistons and the coffee dose. At
the same time, when the brew chamber returns to its
vertical position, the scraper on the coffee hopper holds
the used coffee dose and drops it. The lower piston then
returns to the bottom dead centre.

To refit the coffee unit, pay special attention to the
piston position. Reference notches on the external
disk and on the unit case must match (see Figure 17).

2 - Upper piston
3 - Reference fins
ADJUSTING THE GRADE OF GRINDING
When a variation in the grade of grinding is necessary,
turn the relevant adjusting knob on the grinder (see
Figure 13) as follows:
Fig. 13
1 - Coffee grinder
2 - Grinding adjusting knob
3 - Dose regulator
4 - Dose adjusting lever
5 - Reference notches
-turn the knob anticlockwise for coarser grinding;
- turn the knob clockwise for finer grinding.
For optimum results, it is good practice to vary the grade
of grinding with the coffee grinder motor running.
COFFEE TEMPERATURE CONTROL
N.B.: After adjusting the grade of grinding, at least 2
test selections must be made to check the new
granulometry of the ground coffee:
the finer the grade of grinding the longer the time necessary for dispensing the coffee and vice versa.
If the temperature needs to be changed, adjust the special
trimmer (see figure 21), keeping in mind that:
-
- loosening reduces the temperature;
-
ADJUSTING THE COFFEE DOSE
- the dose is increased by lifting the lever;
the dose is reduced by lowering the lever;
-
every notch changes the dose by approx. 0.25 g.
The machine is supplied with a preset boiler temperature
of 86°C. Water temperature adjustments can be made by
qualified technicians by turning the thermostat screw by
hand (see Figure 14).
In addition, when the lever is fully rotated upwards, the
ratchet can be released from the dose regulator groove
(see Figure 13) and replaced into a different groove to
change the average dose setting to:
- IOW
6 g. k 0.5
-
medium
- high
every 2 turns the temperature varies by approx. 1"C.
INSTANT PRODUCT
TEMPERATURE CONTROL
The dose adjusting lever can be positioned in one of the
6 reference notches, bearing in mind that:
-
tightening increases the temperature;
However, temperature should never exceed 90°, to
prevent water from boiling.
7 g. k 0.5
8 g. f 0.5
To take the dose simply remove the coffee unit and press
key "2" from the "maintenance" menu (see relevant
section).

Access to the machine interior for maintenance andlor
repairs is via the back panel.
Therefore the machine is designed to be rotated, thus
allowing removal of the back panel.
The integrityof thevending machine and itsconformity
with the rules and regulations in force for its relevant
systems must be checked by qualified personnel at
least once a year.
Turn the unit off before any maintenance operations
which require removal of components.
The following operations must be carried out only by
personnel who have the specific knowledge of the
machine functioning from a point of view of electrical
safetyand health regulations.
INTRODUCTION
To ensure perfect 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 onlyageneral 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. boilerdescaling) 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).

lmportant notice!!
Access to the machine interior for maintenance andlor
repairs is via the back panel.
Therefore the machine is designed to be rotated, thus
allowing removal of the back panel.
The integrityof thevending machine and itsconformity
with the rules and regulations in force for its relevant
systems must be checked by qualified personnel at
least once a year.
Turn the unit off before any maintenance operations
which require removal of components.
The following operations must be carried out only by
personnel who have the specific knowledge of the
machine functioning from a point of view of electrical
safetyand health regulations.
INTRODUCTION
To ensure perfect 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 onlyageneral 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. boilerdescaling) 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).
