INSTALLING THE PAYMENT SYSTEM
The machine is sold without payment system, therefore
the installer of such a system is responsible for any
damage to the machine or to things and persons
caused by faulty installation.
- Install the desired coin mechanism according to the
appropriate instructions and make sure that the relevant
parameters are programmed correctly.
- adjust the selector opening lever bracket to allow complete
opening of the selector;
- adjust the coin chute according to the type of coin
mechanism installed.
CLEANING THE SOFTENER RESINS (MOD-
ELS C ONLY)
Before filling the machine water system the resins contained in the softener unit must be cleaned, operating as
follows:
- remove the hose connected to the air-break from the
softener unit fitting (see Fig.16);
- insert a new hose, provided with the machine, onto the now
free hose fitting and direct it towards a drain;
- switch the machine on;
- bleed air out of the softener unit by loosening the plug, wait
until it is full of water and tighten the plug, let a few litres
of water flow out until it is clear;
- re-insert the hose connected to the air-break.
Fig. 16
FILLING THE WATER SYSTEM
If the air-break device indicates the no-water condition for
more than 10 seconds after the machine has been switched
on, an installation cycle will automatically be started, and
namely:
- the display will show
"INSTALLATION"
for the entire duration of the cycle;
- the air-break and the instant product boiler are filled;
- (for espresso models only) the coffee solenoid valve is
opened so that air may be bled from the boiler and 800 cc.
of water filled.
N.B.: If there is no water flow from the mains during the
installation cycle, the machine will be blocked until the
water is resumed or the machine is switched off.
This operation must be carried out by hand, using the
special function from the "test" menu in "Technician" mode,
if the kit (optional) for water supply from an internal tank
is fitted or after any maintenance requiring the boiler to be
emptied but not the air-break.

COFFEE UNIT OPERA TION
COFFEE DISPENSING CYCLE
When selecting coffee, the grinder is started and will
continue until the coffee doser chamber is full (see Figure
17).
When the doser unit is full, the ground coffee dose is
released into the coffee unit.
The coffee falls into the vertical brewing chamber (1) (see
Fig. 18).
The ratiomotor handle engaged with the disk (2) located
outside of the unit rotates by 180°, making the brewing
chamber swing and lowering the upper piston (3) (see Fig.
18).
Due to the water pressure, the pre-brewing spring (5) sinks
and the lower piston (4) goes down 4 mm, thus forming a
water cushion which allows an even use of the coffee dose.
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 solenoid valve,
lightly pressing the used coffee dose.
By completing its rotation, the ratiomotor makes the swinging lever (6) lift the pistons and the coffee dose.
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 bottom dead centre.

CHECKING AND ADJUSTING THE MACHINE SETTINGS
To get the best results from the product used, the following
should be checked:
For coffee
That the used coffee dose is lightly compressed and damp.
The grade of grinding of ground coffee.
The dose weight of ground coffee.
The dispensing temperature.
The water dose.
For instant products
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 instant 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. 85-89°C;
- instant product temperature (at the spout) approx. 75°C;
The machine standard settings assign the same price,
expressed in number of basic coins, to all selections.
ADJUSTING THE BREWING
CHAMBER VOLUME
When the upper piston is correctly positioned, the coffee
unit can operate with coffee doses of 5.5 to 8.5 g.
To change the piston position (see Fig. 19) do as follows:
- remove the snap ring from its seat;
- place the piston in the proper adjusting notches:
.less deep notches for 5.5 to 7.5 g doses;
.deeper notches for 6.5 to 8.5 g doses.
Fig. 19
1 - Snap ring
2 - Upper piston
3 - Reference fins
ADJUSTING THE COFFEE DOSE
The dose adjusting lever can be positioned in one of the 6
reference notches bearing in mind that:
- 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.
In addition, when the lever is fully rotated upwards, the
ratchet can be released from the groove in the dose
regulator (see Fig.20) and replaced into a different groove
to change the average dose setting to:
- low 6 g ± 0,5
- medium 7 g ± 0,5
- high 8 g ± 0,5
To take the dose it will be sufficient to remove the coffee
unit and use the special function from the “test” menu in
“Technician” mode (see relevant paragraph).
Important notice!!!
To refit the coffee unit, pay special attention to the
piston position. Reference notches on the external disk
and on the unit case should match (see Fig. 23).
ADJUSTING THE WATER TEMPERATURE
The boiler temperature is controlled by the software and can
be adjusted directly from the menu.
ADJUSTING THE GRINDER
When a variation in the grade of grinding is desired, turn the
relevant adjusting knob on the grinder (see Fig. 20) and
more specifically:
- 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.
N.B.: After adjustment of the grade of grinding, at least
2 test selections must be performed in order 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.

credit is available for further selections. When pressing the
coin return button, the available credit is returned if its value
is lower than the maximum change value.
Credit control
This function enables/disables the return of credit if no
selections are made.
If enabled, this function will hold the credit until the first
selection has been made. If however a selection fails for
any reason, the change will be returned if requested.
Maximum credit
This function is used to define the maximum accepted
credit.
Maximum change
It is possible to set a limit to the total amount of change
returned by the coin mechanism when pressing the coin
return button or after a single dispensing serving.
The value can be 0 to 250 basic coins. Any credit exceeding
the amount programmed with this function will be cashed.
Accepted coins
It is possible to define which, among the coins recognised
by the validator, are to be accepted.
Check the label on the coin mechanism for the correct coin
to value matching, indicating the position of the coins.
Rejected coins (BDV only)
This function programs the rejection of coins when in “exact

to value matching, indicating the position of the coins.
Disabled coin return (MDB only)
This function disables the return of a specific coin.
Dispensing buttons (BDV only)
This function enables or not the buttons on the coin
mechanism used to release the coins in the change return
tubes.
Value of “exact amount” (BDV only)
This value defines the combination of empty coin tubes,
setting the coin mechanism in “exact amount” mode. The
possible combinations of empty coin tubes are indicated
below. For greater simplicity, the combination is described
with reference to tubes A, B and C, where tube A receives
the lower value coins and tube C the greater value coins.
0 = A or (B and C)
1 = A and B and C
2 = A and B only
3 = A and (B or C)
4 = A only
5 = A or B only (default)
6 = A or B or C
7 = A or B only
8 = A or C only
9 = B and C only
10 = B only
11 = B or C only
12 = C only

C.P.C. devices (BDV only)
It dialogues with the coin mechanism if devices are installed or removed from the serial interface (C.P.C.-type
devices - the monitoring unit is always enabled by default).
Minimum level of tubes
It brings forward the “Insert exact amount” message for the
user, by adding a number of coins between 0 and 15 to the
programmed number of coins, to set the “full change tubes”
status.
Free Vend (BDV only)
Most payment systems with the BDV protocol control the
free vend function.
However, there are some payment systems without such
function.
In this case, if free selections are to be dispensed, free
vending must be enabled with VMC (vending machine
control, disabled by default) and the price of the selections
must be set to zero.
COMMON FUNCTIONS

SELECTIONS
The selection menu is composed of various sub-menus
which allow setting of the different parameters.
WATER DOSE
The water dose, expressed in cc, can be set for each
selection button and therefore each product assigned to it;
the display indicates the name of the product being selected.
It is also possible to set the water flow rate of the single
solenoid valves expressed in cc/s (the default value setting
in cc/s is indicated in the selection dose table) to calculate
the amount of water to be dispensed.
WHIPPER CONTROL
The whipping duration can be set for each selection button
and therefore for each water dose composing the selection.
The duration can be set in two main modes:
absolute
that is, independently from the solenoid valve opening
time. The whipping duration is set in tenths of a second for
the instant models and volumetric counter pulses for the
Espresso models.
relative
that is, as the difference, more or less, from the moment
of closing the solenoid valve.
The whipping duration is always expressed in tenths of a
second.
POWDER DOSE
The powder dose, expressed in grams, can be set for each
selection button and therefore each product assigned to it;
the display indicates the name of the product being selected.
For correct conversion of product dose values, the flow rate
of the single dosing units, expressed in g/s, can be set to
calculate the amount of powder to be dispensed.
It also possible to program the doses of a product “Globally”, i.e. setting all selections with a single operation.
ACCESSORIES
Dispensing of sugar, stirrer and cup can be enabled or
disabled for each single selection button.
SELECTION STATUS
Each single selection button can either be enabled or
disabled.
