I. SAFETY PRECAUTIONS
I.I LEVEL OF TRAINING AND
INFORMATION REQUIRED OF
MAINTENANCE TECHNICIAN
Maintenance Technician is a qualified
person that is specially trained and au-
thorised to carry out the machine con-
nection, installation, assembly and main-
tenance operations in compliance with
the applicable regulations.
MaintenanceTechnician must be properly
trained and informed as work on residual
risks resulting from these operations and
while the machine is in use.
A Maintenance Technician must be able
to apply all good practices in compliance
with food hygiene principles.
I.II SAFETY PRECAUTIONS
Even though the machine is provided with
all safety devices required to eliminate
possible risks for the Maintenance
Technician, there are still certain residual
risks.
These so-called residual risks are related
to machine parts that may pose a risk
to the Maintenance Technician, if used
improperly, evaluated or deactivated
incorrectly, because the prescriptions
contained in this Manual were
circumvented.
The machine is also equipped with
appropriate warnings placed on residual
risk areas, which must be scrupulously
observed.
Compliance with the installation and
machine’s safety standards is dependent
on the use, installation, maintenance
and correct operation of the machine.
These factors are the responsibility of
the purchaser, installer and installer’s
employer.
The installer’s employer is responsible for
hiring and training personnel to correctly
install, run and perform maintenance
work on the machine and its protection
systems:

I.III TRANSPORT AND HANDLING
Hand crushing hazard
Handling operations must always and
exclusively be performed by Maintenance
Technician and in compliance with the
current health and safety regulations.
Before starting the transport and/or
handling manoeuvres, check the route,
dimensions needed, safety distances,
places suitable for placing the load down,
and the appropriate equipment for the
operation.
Handling operations must be carried
out by at least 2 people, or with the help
of special lifting equipment.
In view of the substantial weight of the
equipment, exercise great caution during
the handling operations.
The Manufacturer is not responsible for
any injury or damage caused by clothing,
lifting equipment and personal equip-
ment which was not suitable for the type
of intervention that the operator had to
carry out.
The packaging material must not be
left within the reach of children, since it
is a potential source of danger.
I.IV INSTALLATION
Electrical hazard
Equipotential hazard
High temperature hazard
Do not perform maintenance
on moving components
Installation must always and exclusive-
ly be performed by Maintenance Techni-
cian and in compliance with the current

vide water which is suitable for human
consumption, and must conform with
the regulations in force in the place of
installation.
The installer must carry out the hydrau-
lic connections in accordance with the
hygiene norms and the hydraulic safety
norms for environmental protection in
force in the place of installation.
This appliance is to be considered com-
pletely safe only when it is connected to
an ecient earthing system which com-
plies with safety standards.

2.9 Energy Saving System
The machine is equipped with software that man-
ages the automatic stand-by system during breaks, the
night Energy-saving feature and the smart temperature
adjustment.
This allows saving a considerable amount of energy
during night breaks, whilst maintaining the machine in
a condition that permits a quickly return to operation.
Moreover, the software only distributes the power
where and when needed, thus allowing energy to also
be saved during normal operation.
If provided for in the programming, the software
automatically puts into stand-by one or more groups
when the workload decreases, also preparing them for
full capacity when needed.
Three choices are provided:
• : manual standby activation
• : programmed operation
• : self-learning management
For Energy saving activation see par. 7.13 on page 16.
2.9.1 Coee heating unit
Each dispensing group is tted with a thermally-
insulated coee heating unit (1) for dispensing hot water
for coees.
Heat is provided by an
electric heating element
(2). The heating unit in-
cludes a temperature sen-
sor (3) and a safety ther-
mostat (4).
The temperature sensor
(3) regulates and stabilises
the water temperature in-
side the coffee heating
unit. The safety thermostat (4) intervenes in the event
of a heating system malfunction. If the temperature
reaches 150°C, the safety thermostat intervenes by dis-
abling the heating element and reporting the problem
on the display.

2.9.3 Dispensing group
The dispensing group (A) is made up of a metallic
block which is hooked onto the coee heating unit (B).
The functions of the group are summarised as follows:
• When the motor pump and solenoid valve (C) are
activated, which are located on the side of the group,
this allows cold water to enter the heating unit (D),
and consequently the hot water in the heating unit is
carried towards the group to be dispensed (E);
• The electric cartridge heating element (F) which is in-
stalled inside the group, is controlled by the electronic
control unit and heats the group at a programmed
temperature;
• The temperature sensor (G) detects the group’s tem-
perature and sends it to the electronic control unit;
• The safety thermostat (H) cuts in to prevent any risks
if there is a failure in the electronic system.

2.9.4 Electronic control unit
The electronic control unit is the ma-
chine’s “brain”, since it monitors and con-
trols the appliance’s full operation.
The information concerning the in-
stalled software (date and version) can be
seen on the display when the machine is
turned on. The monitoring and control of
the appliance’s full operation.
The information concerning the in-
stalled software (date and version) can
be seen on the display when the machine is turned on.
2.9.5 Volumetric dosing
The volumetric dosing device measures the quantity
of water sent to the group in order to dispense coee.
The dosing device generates an electrical impulse
which is sent to the electronic
control unit.
The dosing device gener-
ates electrical pulses that are
sent to the control unit and
get counted when the dose is
being programmed.
2.9.6 Motor pump
THIS is a component that
feeds the machine, by raising
the water pressure to 8 - 9
bar in order to dispense cof-
fee and automatically ll the
heating unit.
2.9.7 Automatic Water Entry
The Automatic Water Entry system (AWE) is designed
to check the water level of the heating unit. It consists of:
• A level probe (short) (1) and safety probe (long) (2)
inserted in the heating unit, composed of a stainless
steel rod;
• An electronic control unit;
• A hydraulic circuit with a motor pump and solenoid
valve which are controlled by the electronic control
unit.
If the water level drops while the machine is operat-
ing normally, the level probe (1) sends a signal to the
electronic control unit, which activates the motor pump
and the lling solenoid valve, which in turn restores the
water level in the heating unit.
If the level is very low or there is no water in the
heating unit (during the machine's installation or due
to a failure), the safety probe (2) sends a signal to the
control unit which deactivates the heating element to
keep it from overheating and activates the motor pump
and the solenoid valve to restore the level of water in
the heating unit.
To prevent any ooding caused by machine mal-
functions or leaks in the hydraulic circuit, the electronic
control unit has a “Timeout” device which stops the
automatic water lling operation after a maximum op-
erating time.
When installing machines with three or four groups,
the initial water lling time may exceed the established
timeout limit. Should this occur, simply turn the machine
o and then back on to restore normal operating condi-
tions.

2.9.8 Pressure switch
The machine has two types of pressure switches:
COFFEE HEATING UNIT PRESSURE SWITCH
Each coee heating unit is equipped with
a pressure switch to adjust the pressure.
The calibration is set to 2 bar.
STEAM HEATING UNIT PRESSURE SWITCH
The steam heating unit is instead tted
with a safety pressure switch which prevents
the calibration value from being exceeded.
The calibration is set to 1.5 bar.
2.9.9 Overow device
The cover installed
on the pressure relief
valve makes it possible
to collect any water
and steam which may
leak from the heating
unit due to a malfunc-
tion and channel it to
the drain tray, via a
special hose.
2.9.10 Pressure relief safety valve
The pressure relief safety valve has a
calibration of 1.9 bar in order to ensure that
the pressure in the steam heating unit does
not exceed 2.1 bar. Should a fault occur, the
capacity of the valve is such as to be able
to eliminate all the excess pressure in the
heating unit.
Thesafetyvalveshouldbecheckedregularly,asindicatedinChap.
9.3, on page 18.
2.9.11 Pressure transducer
The pressure transducer converts the
pressure into an electrical signal that
can be managed remotely (e.g., from the
display).
2.9.12 Pre-infusion solenoid valve
The pre-infusion solenoid valve al-
lows hot water to reach the coee at
low pressure before the pressure of the
pump arrives.
2.9.13 Expansion - check valve
• check valve: the check valve is placed in series with
the hydraulic circuit that feeds the
water-coee boilers. It is used to block
expansion pressure.
• Expansion valve: the expansion valve
is placed in series with the hydraulic
circuit that feeds the water-coee boil-
ers. It is used to limit the expansion
pressure value.
2.9.14 Thermostat
The thermostat prevents any damage occurring to
the electrical heating element if there is no water in the
heating unit. The thermostat bulb (3) is located inside
a sheath (1) in the middle of the heating elements. The
thermostat contacts (4) are connected to the electric
heating element (2). If the electric heating element is
exposed due to a failure to ll the heating unit with
water, the temperature of the heating element increases
dramatically. At this point, the thermostat cuts the power
supply to the heating element in order to prevent dam-
age occurring.

To change the temperature of the cup warmer, see para. 9.1.4,
on page 19.
2.9.16 Water lter
In the mains water, non-soluble
salts are present which cause lime-
stone to form in the heating unit and
other parts of the machine.
Drinking water can also contain
heavy metals and substances, such as
chlorine which are harmful to health.
The filter makes it possible to
eliminate or substantially reduce the
presence of these mineral salts.
The cartridge contained in the
water lter must be replaced at the fre-
quency specied by the manufacturer.
To use and maintain the water filter, follow the instructions
provided in para. 9.4, on page 20.
2.9.17 Water softener
The resin softener can be used as an
alternative to the water lter.
This component has the property of
retaining the calcium contained in the
water. For this reason, the resins become
saturated after a certain period and must
be regenerated with coarse kitchen salt
(NaCl, sodium chloride) or special water
softening salt. It is very important to
regenerate the softener within the established times.
However, in locations where the water is very hard, it will
be need to be regenerated more frequently. The same
rule can be applied to locations where there is a large
consumption of hot water (for tea, etc.).
To use and regenerate the water softener, follow the instructions
provided in para. 9.5, on page 20.
