IN CASE OF FAILURE
In most of the cases technical problems can be solved
by means of small interventions; we therefore suggest to
read this manual carefully before contacting the manufacturer.
In case of anomalies or malfunctioning which cannot be
solved, please contact:
Foreword
The technical documentation forms an integral part
of the equipment and must therefore accompany
any movement or transfer of ownership in order to
allow further consultations by the operators.
Before installing and using the equipment you need to
scrupulously read and understand the contents of the
documentation, as it provides important information
related to installation safety, to the utilisation standards
and to the maintenance operations.
The manual is divided into three chapters.
The first chapter describes the loading and ordinary
cleaning operations to be performed in the areas of the
machine which can be accessed through just the use
of the door opening key, without the need of using other
tools.
The second chapter contains the instructions related
to a correct installation and the information required to
make the best use of the machine.
The third chapter describes the maintenance operations which require the use of tools for accessing potentially dangerous areas.
The operations described in the second and third
chapter shall be carried out only by personnel with
specific knowledge of the operation of the machine
both from the point of view of electrical safety and
of hygiene.

3
In accordance with current health and safety regulations,
the operator of a vending machine is responsible for the
hygiene of the materials which are in contact with food
products; the operator shall therefore carry out maintenance interventions on the machine so as to prevent the
formation of bacteria.
When the machine is installed, the hydraulic circuits and the parts in contact with the food products need to be sterilised in order to eliminate any
bacteria which could have formed during storage.
It is recommended that sterilising products also be used
when cleaning the surfaces which are not directly in contact with the food products. Some parts of the machine
can be damaged by aggressive detergents.
The manufacturer shall not be held responsible for any
damage caused by the non-observance of the above or
by the use of aggressive or toxic chemical products.

WATER SUPPLY
Anti-flooding device
The water inlet solenoid valve (see Fig. 18) is equipped
with an anti-flooding device which allows the mechanical
blocking of the input of water following a malfunction of
the solenoid valve or of the control system of the level of
water in the boiler.
For restoring the normal operations, do as follows:
- empty the water contained in the anti-flooding pipe;
The water used by the vending machine is drinking water, taking into account the regulations in force where the
machine is installed.
The machine should be connected to the drinking water
mains with water pressure between 0.05 and 0.85 MPa
(0.5-8.5 bar).
Let the water come out from the mains until it is clear and
free from dirt.
Connect the water mains to the 3/4” connection of the
water inlet solenoid valve (see Fig. 18) with a pipe having
minimum internal diameter of 6 mm (also available as a
kit), suitable for supporting the mains pressure and of a
type suitable for food products.
Installing a tap on the water system outside the machine, in an accessible position, is recommended.
To connect the machine to the water mains use only
one set of new gaskets and hoses. Do not reuse the
material that may exist.
- close the water mains tap outside the machine;
- loosen the connection which fixes the input pipe of the
solenoid valve for lowering the residual water pressure
and tighten it again (see Fig. 18);
- open the tap and apply voltage to the machine.
Descaler
The machine is supplied without descaler.
In the event that the machine is connected to very hard
water, it is necessary to install a descaler.
Use descalers with a capacity which is adequate to the
actual use of the machine.
In case the machine uses a water tank, it is possible to
use appropriate filtering cartridges.
The cartridges will need to be replaced periodically
depending on the water quality and the indications given
by the manufacturer.
The descalers, also available as an accessory, need to
be periodically regenerated or replaced according to the
manufacturer's instructions.

ELECTRICAL CONNECTION
It is necessary to verify this fundamental safety
requirement and, in case of doubt, request an accurate check of the system by qualified personnel.
The power supply cable has a non-separable plug. The
replacement of the connection cable (see fig. 19) shall
be carried out only by qualified personnel and using
only cables of the type HO5 RN - F or HO5 V V-F or H07
RN-F 3x1-1.5 mm2 cross section.
The use of adapters, multiple plugs and/or extension cables is forbidden.
The machine requires a single phase voltage of 230 V~
and it is protected by a 15 A fuse.
For the connection, make sure that the plates data correspond to the mains data, and in particular:
- the value of the voltage shall be within the recommended limits;
- the general switch shall have suitable characteristics
for supporting the maximum load requested and it shall
ensure an omnipolar switch-off with a switch-contact
gap of at least 3 mm.
THE MANUFACTURER SHALL NOT BE HELD RESPONSIBLE FOR ANY DAMAGE CAUSED BY THE
NON-OBSERVANCE OF THE ABOVE-MENTIONED
PRECAUTIONS.
The switch, the socket and the plug shall be placed
in an accessible position.
The electrical safety of the machine is ensured only
when the machine is correctly connected to an efficient
earthing system, as foreseen by the current safety regulations.

First sanitization of the mixers and
Installation in series
The machine control system is arranged for connection
in series with other vending machines, by using appropriate kits.
This connection permits the use of one payment and remote connection system only (GSM) for several machines.
In case of installation in series, the machine can be
configured as “Master”, therefore assuming control of
the second machine, or as “Slave”, therefore leaving the
control to the other machine.
of the food product circuits
When the machine is installed it is necessary to carry
out an accurate sanitization of the mixers, of the instant
drinks dispensing pipes and of the internal tank in order
to ensure the hygiene of the distributed products.
Jets of water are to be absolutely avoided for cleaning.
The sanitization is performed by means of sterilising
products.
Wash the mixers and add a few drops of sterilising solution
Once the sanitization has been performed, rinse the
mixers well for removing any possible residue of the solution
used.
For letting water inside the mixers, use the button “mixer
wash”; if necessary, enable it from the menu (see paragraph on the dispenser's parameters)
Important!
The machine is equipped with an automatic washing system for the mixers with relative hydraulic
circuit and the infuser unit.
If the use of the machine is subject to idle periods (weekends, etc.), even for less than two days, it is good practice to enable the automatic washing functions (before
beginning to use the DA for example)
(see “Engineer menu - Configuration - Mixer wash and
Infuser unit wash”)

ESPRESSO UNIT
At the end of the coffee dispensing phase, the upper
piston goes down in order to mechanically squeeze the
coffee pod, facilitating the expulsion of excess water
through the 3rd route of the dispensing solenoid valve.
At the end of the cycle the gear motor is activated in the
opposite direction, lifting the upper piston and rotating
the infusion chamber towards the emptying side, on the
opposite side of the dispensing side; the lower piston (8)
rises.
Once the emptying position is reached, the gear motor
inverts its rotation direction again, bringing the infusion
chamber back to the idle position.
The scraper (3) holds the coffee pod and lets it fall, while
the lower piston (8) returns to the idle position.
After each start-up of the machine, the coffee unit performs a full rotation before performing the normal cycle in
order to ensure that the device is positioned in the initial
position.
Coffee dispensing cycle
If a coffee-based selection is requested, the grinder is
activated until the coffee doser chamber is full.
When the doser is full, the coffee dose is released into
the infusion chamber which is located vertically inside
the coffee unit (see Fig. 20-1).
The gear motor engaged on the pinion (6) lets the cranks
(5) rotate, which cause the infusion chamber (1) to rotate
by 30° (Fig. 22, Item 7).
The upper piston (1) aligns itself with the infusion
chamber (Fig. 22 -7) and descends inside it. The position
where the piston stops for the infusion will depend on the
quantity of ground coffee in the chamber.
Volume of the infusion chamber
The coffee unit can operate with coffee doses between
5.5 and 8.5 g.
The upper piston positions itself automatically.

Checks and settings
Reposition it differently to vary the average adjustment as:
Low
6 g. ± 0.5
Average
7 g. ± 0.5
High 8 g. ± 0.5
For collecting the dose it will be sufficient to remove the
coffee unit and use the appropriate function of the "test"
menu in "engineer" mode (see relevant paragraph).
To obtain the best results for each product used, we
recommend the following checks:
--The coffee pod shall be slightly compressed and moist.
--Granulometry of ground coffee.
Grammage of ground coffee.
--Dispensing temperature.
Manual grinding setting
--Dose of water.
If the grinding grade needs to be changed, adjust it using the relevant knob on the grinder (Fig. 23), and more
precisely:
- rotate anti-clockwise for obtaining a larger grinding;
COFFEE GRINDER
On the appliance, according to the model, can be
mounted one or two grinders.
Only one of the two grinders can be (optionally)
equipped with a device for automatic adjustment of the
grind.
The operations described in this section refer to a single
grinder.
- rotate the knob clockwise to obtain finer grinding.
It is good practice to change the grinding grade when the
coffee grinding motor is working.
NB: after varying the grinding grade, it is necessary
to carry out at least 2 selections for checking the
new ground coffee granulometry:
Coffee grammage adjustment
The dose adjustment lever can be positioned on
one of the 6 reference notches, taking into consideration that:
The finer the grinding grade, the longer the dispensing
time will be and vice versa.
- if the lever is lifted the dose increases:
8
- if the lever is lowered the dose decreases:
7
- each notch varies the dose by approx. 0.25 g.
Furthermore, by fully rotating the lever upwards, it
is possible to release the tooth from the notch on
the dose adjustment device (see Fig. 23)

Automatic grinding setting
Blades wear control
The control function of the blades gives a warning message of "Worn blades" when the machine is turned on,
when the grinding time increases too much compared to
the grinding time of when the blades were new.
The replacement of the blades, the saved average grinding time will be reset with the special menu.
Software adjustment of the grinding
If for any reason, such as maintenance on the blades,
major changes in the distance are required, you can set
the desired changed value manually via software.
This value is expressed as 1/6 of a turn of blade-holder
ring.
for increasing grain size (larger grinding), the automatic
adjustment takes place in a single operation;
for decreasing the grain size (finer grind) the automatic
adjustment takes place with the coffee grinder engine
running.
Warning! If the variation is large, the dispensing
chamber is filled, the coffee is dropped. It 's better
to intercept it to prevent clogging of the infuser.
On one of grinders can be fitted a device that automatically regulates the distance between the blades, and
therefore the grinding, by default or optionally.
The device for automatic adjustment of the blades (Figure 23) allows for the quality of the dispensed beverage
to stay constant, by compensating for variations due to
the product, the environment and wearing of the blades.
Reference selection
To properly monitor the parameters of the automatic
adjustment of the grinding (grinding time and infusion
time), the machine makes a selection as a reference for
the implementation of automated devices.
The device monitors the infusion time required (software
programmable) for the delivery of a quantity of water
corresponding to a (fixed) number of pulses of the flow
meter (cdv) is actually be achieved, otherwise the degree of grinding varies acting on the bi-directional motor
that controls the distance between the blades.
When, from the programming menu, you choose to
intervene on the grinder, the LED of the selection set as
a reference lights up.
Based on this selection, and on those with comparable
doses, the infusion time and the time to grind the coffee
dose will be measured, so subsequent measurements
will be made on this selection.
The change of the grinding is due to the variation of the
infusion time required; the grinders are placed closer to
one another gradually (finer grain), to avoid compressing
the coffee.
Please Note: To check for sure the new infusion
time, keep in mind that the effect of the automatic
adjustment of the grind, is seen after a few selections.
After the adjustment has been stabilized, you should
also check the amount of ground coffee that can undergo small variations.
Automatic setting lock
For whatever reason it should prove necessary, it is possible to stop the operation of the automatic adjustment.
The grinders are stopped at the distance they have when
the automatic adjustment is stopped.

Calibration
Other selections
The selected layout defines the dose of a given selection. For selections of reference, the infusion time is a
non-changeable value and is linked to the selection of
reference.
Water Dose
The amount of water (expressed in cdv) to be dispensed
on each selection can be defined via software. Coffee
dose and infusion time are those defined for the selection of reference.
Coffee dose combination
Even though this combination can be changed, the
choice to do so should be made very carefully since it
has a substantial effect on the quality of the dispensed
drink.
Reference selection
The reference selection LED lights up when you select
the grinder on which you intends to intervene.
The selection is determined by default and you cannot
change it.
Coffee dose
The maximum coffee dose used by the infuser group is
9 grams.
The dose adjustment should be made first, by acting
manually on the coffee dispenser lever.
Water Dose
The type of selection determines the amount of water to
be delivered in terms of volumetric meter pulses (cdv).
After setting the value of water on the selection of reference, the machine will ask you to enter the infusion time.
Infusion time
The degree of the grinding has a direct effect, if the
coffee and water doses are the same, on the time of
infusion.
By changing this value, the system of automatic adjustment of the grinding, acts to align the actual time with
that required.
During normal operation, continuous monitoring of this
time allows the optimum degree of grinding.

INSTANT DRINKS DISPENSING
Preselections
Based on the layout that has been set on the machine,
it is possible to have different preselections; the preselections foreseen for each layout are described in the
doses-selections table (layout selections) supplied with
the machine.
The dispensing cycles of the various selections are studied for obtaining the best result in terms of productivity
and quality of the drinks.
The instant drinks are dispensed following a recipe in
which the ingredients (max 4) are identified with a number and the product name and described by the water
and product quantities and the dispensing and mixing
times.
Dosers calibration
For the correct conversion of the amounts of the product
dose it is possible to set the value of the rate of each
of the dosers in g/sec for calculating the grams to be
dispensed.
These values are programmable via software with appropriate functions.
Even the dispensing order of the individual ingredients
within a recipe is programmable.
The powder for chocolate-based selections is dispensed
intermittently, whereas the powder for coffee-based
selections is dispensed before the water.
-Warning !!!
Adjustment of the water temperature
The temperature of the boiler is controlled by the software:
Default condition:
-99.6° C for the espresso boiler
and it can be adjusted directly from the menu.
Make sure that the mixer is rinsed correctly without
leaving any powder residue.
Variation of the setting for instant products
The grammage of the instant products, the dose of water
and the temperature are controlled directly by the microprocessor.
The variation of these values is therefore performed
through the programming procedures.

ESPRESSO UNIT MAINTENANCE
Chapter 3
Every 10,000 dispensed items or, however, every 6
months, a small maintenance intervention on the coffee
unit is required for optimising its operation.
For performing the maintenance operations it is necessary to remove the unit by following these steps:
--Disconnect the coffee outlet nozzle (2) from the unit by
rotating it by 90° from the rod (4) and pulling it outside.
Maintenance
The integrity of the machine and compliance of the
corresponding systems with the regulations shall
be verified, at least once a year, by qualified personnel.
Always switch off the machine before starting
maintenance operations which require the disassembling of components.
--Act the unit end stop lever (8) rotating it until the horizontal position.
--Extract the coffee unit.
The operations described below shall be carried
out only by personnel with specific knowledge of
the operation of the machine both from the point of
view of electrical safety and of hygiene.
Disassemble/replacement of the filter and upper seal
In order to disassemble or replace the filter and the upper seal, follow these steps:
--Unscrew the key (6) fixing lateral screw (5) of the upper
piston.
GENERALITIES
In order to ensure its correct operation, the machine
shall be subject to periodical maintenance.
Listed below are the operations to be carried out and
the related expiry dates; they are, obviously, indicative
because they depend on the conditions of use (i.e. water
hardness, environment humidity and temperature, type
of product used, etc.).
The operations described in this chapter do not include
all the maintenance interventions.
More complex interventions (i.e. descaling of the boiler)
shall be carried out by an engineer with specific knowledge of the vending machine.
In order to avoid risks of oxidation or of chemical aggressions in general, the painted surfaces and the surfaces
in stainless steel need to be kept cleaned by using neutral detergents (avoid solvents).
Jets of water are to be absolutely avoided for washing the machine.
--Rotate the upper piston (1) upwards.
--Remove and replace the upper seal (7).
--Unscrew the upper filter (9) so that it can be removed
and replaced.
Disassembling/replacement of the filter and
lower seal
In order to disassemble or replace the filter and the lower
seal, follow these steps:
--Manually bring the unit to the discharge position with
the lower piston (12).
--Unscrew the central fixing screw for removing the filter
(10).
--Press on the end of the piston stem guide (14) for obtaining an extra run of the lower piston (12).
--Pull with a small screwdriver for sliding the lower piston
(12) out from the piston stem (14) being careful not to
damage the piston or the sealing elements
--Remove and replace the lower seal (13).

BOILER CONTROL BOARD
BOILER MAINTENANCE
Depending on the mains water hardness and on the
number of selections made, a descaling of the boiler
could be required.
Warning!
The boiler is sealed (cannot be open); therefore, the
scaling operation must be performed only by qualified
service personnel. using liquid descaling products.
To perform the descaling it is necessary to disassemble
the boiler from the apparatus.
For descaling only use non-toxic and non-aggressive biodegradable products.
Rinse well before reassembling the components.
When reassembling, make sure that:
--the electrical connections (terminals, faston, etc...) are
perfectly dry and well connected

BOILER THERMAL PROTECTION
FAN REPLACEMENT
The espresso boiler has 2 contact safety thermostats
(klixon), which deactivates the boiler resistance in case
the temperature of the water exceeds the safety temperature (125°C).
An additional thermostat with capillary will stop the power
supply when the boiler reaches a temperature of 130° C
without the presence of water (dry).
In case of intervention of one or more thermostats, the
system shall be restored manually with the proper button, after having eliminated the cause of the fault.
To restore the dry functioning protection thermostat remove the protective cover of the reset button and press
the button itself, then replace the cover.
Important!
In case of intervention of one or more safety devices it is
necessary to replace the boiler temperature probe and
seals of the fittings on the boiler itself, as they might be
potentially damaged irreversibly.

Access to the vapor suction fan occurs from the inside of
the unit.
If for any reason it becomes necessary to intervene on
the fan, remove the soluble containers from the device
and remove the appropriate cover
Important!
The covers need to be removed after disconnecting
the machine from the power supply.
