carried out 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.
Do not use adapters, multiple sockets and/or extensions.
It is good practice to install the water supply tap
outside the machine in an easily accessible position.
OVERFLOW DEVICE
The water inlet solenoid valve (see Fig. 13) is equipped
with an overflow device which mechanically stops the
water inlet if there is a malfunction in the solenoid valve or
in the boiler water level control device.
To restore normal operation, proceed as follows:
- disconnect the electricity from the machine;
- drain the water contained in the overflow hose;
- shut off the water supply using the tap outside the
machine;
- loosen the nut which secures the solenoid valve supply
hose to relieve the water mains residual pressure and
then tighten again (see Fig. 13);
- open the tap and switch the machine on.
CONNECTING THE MACHINE TO THE
POWER SUPPLY
The machine is designed to operate under single-phase
230 V~ voltage and is protected by 15 A fuses.
Before making the connection, ensure that the rating
corresponds to that of the power grid, and more specifically:
- the supply voltage rating must be within the range
recommended for the connection points;
- the main switch should be capable of withstanding the
peak load required, and at the same time ensure proper
omni polar 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.
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.
Fig. 13
THE MANUFACTURER DECLINES ALL RESPONSIBILITY FOR ANY DAMAGE CAUSED BY NON-COMPLIANCE WITH THE ABOVE MENTIONED PRECAUTIONS.
DOOR SWITCH
When opening the door a special micro-switch disconnects the power from the machine electrical system.
To energize the system with the open door, simply insert
the special key into the slot (see Fig. 11).
With the door open, there is no access to energised

INSTALLING THE PAYMENT SYSTEM
The machine is sold without payment system, therefore the installer of such a system has sole responsibility for any damage to the machine or to things and
persons caused by incorrect installation.
Install the coin mechanism paying attention, according to
the type used, to:
- securing the coin mechanism onto the support, choosing
the most suitable securing holes;
- loosening the fastening screw and adjusting the coin slot
chute according to the coin mechanism opening;
- loosening the fastening screws and adjusting the selector
opening lever.
Fig. 16
- 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. 15
CLEANING THE SOFTENER RESINS
(MODELS 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;
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 manually, 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.
INSTALLATION IN A BANK OF MACHINES
The machine control system is pre-arranged for the connection in a bank of vending machines using special kits.
This permits the use of a single payment system and
remote connection (GSM) for more machines.
In the event of installation in a bank of machines, it can be
configured a “Master”, i.e. having control over the second
machine, or as “Slave”, i.e. leaving the control to the other
machine.

COFFEE UNIT OPERATION
COFFEE DISPENSING CYCLE
When selecting coffee, the grinder is started and will
continue until the coffee doser chamber is full (see Fig. 20).
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 assembly rotates by 180°, making the brew
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 tea 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.
Fig. 17
Fig .18
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 coffee.
The dose weight of ground coffee.
The dispensing temperature.
The water dose.
For instant products
The weight of instant products.
The drink temperature.
The water dose.
Should the standard settings be varied, 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) 85-89°C approx.;
- instant product temperature (at the spout) 75°C approx.;
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 gr.
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 gr. doses;
.deeper notches for 6.5 to 8.5 gr. doses.
Fig. 19
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 gr.
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 gr. ± 0.5
- medium 7 gr. ± 0.5
- high 8 gr. ± 0.5
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. 20) and
more specifically:
- 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.
NB: After adjustment of the grade of grinding, at least
2 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.

PROGRAMMING PARAMETERS
CASH
This set of functions controls all parameters regarding the
payment systems and the sales prices.
SELECTION PRICES
Four different prices can be set for each selection according to the programmed time bands for when the time table
option is enabled.
For each of the 4 time bands prices (0 to 65,535) can be
programmed globally (same price for all selections) or for
the single selections.
Should the majority of products be sold at the same price,
it will be convenient to set the price globally and then
change the figure of the selections with different prices.
TIME BANDS
Four programmable time bands are provided for selling
products at different prices.
The time periods are programmable for beginning and end
time by hours (00 to 23) and minutes (00 to 59).
If the values for start and end of the time band are set to
00.00 the time period is disabled.
The reference time is kept by an internal clock, programmable as:
day/month/year week-day 1-7
and then
hour/minutes/seconds.
COIN MECHANISMS
