2.6.1 Coee boiler
Each dispensing group is equipped with a thermally
insulated coee boiler (1) for coee hot water dispensing.
Heat is provided by an electric heating element (2).
The boiler includes a tem-
perature sensor (3) and a
safety thermostat (4).
The temperature sensor
(3) regulated and stabilizes
the water temperature in-
side the coee boiler. The
safety thermostat (4) in-
tervenes in the event of a
malfunction of the heating
system. After reaching 150
°C the safety thermostat
intervenes to disable the heating element and to report
the problem on the display.
2.6.2 Services boiler
The totally insulated services boiler (5) is used to
produce steam for hot water, for milk frothing with the
cappuccino maker or auto steamer (optional), and to
heat/foam beverages.
The water in the boiler is heated by an electric heat-
ing element (6).

2.6.3 Dispensing group
The dispensing group (A) is made up of a metallic
block which is hooked onto the coee boiler (B).
The features of the group are summarized as follows:
• the activation of the motor pump and solenoid valve
(C) located on the side of the group allows the cold
water to enter the boiler (D), consequently the hot
water in the boiler is carried towards the dispensing
group (E);
• the electrical cartridge heating element (F) installed
in the group is controlled by an electronic control unit
and allows the group to be heated at a programmed
temperature;
• the temperature sensor (G) detects the value of the
temperature of the group and sends it to the elec-
tronic control unit;
• the activation of the safety thermostat (H) prevents
risks if there is a failure in the electronic system.

2.6.4 Electronic control unit
The electronic control unit is the nerve
center of the machine. It monitors and
controls all operation of the unit.
By entering the section "Menu" (see
instructions in the next chapters) and se-
lecting the key , you can view the
information about the installed software
(date and version).
2.6.5 Volumetric dosing
The volumetric dispenser serves the purpose of
measuring the quantity of water sent to the group for
coee dispensing.
The dispenser generates an electrical pulse which is
sent to the electronic control unit.
The dispenser generates
electrical pulses that are
sent to the control unit and
counted during program-
ming of the dose.
The ashing of the LED (X)
indicates that the electrical
impulse has been sent from
the dispenser to the control
unit.
2.6.6 Motor pump
This is a component that
feeds the machine, raising
the water pressure to 8 - 9
bar for coffee dispensing
and automatic lling of the
boiler.
X
2.6.7 Automatic Water Entry
The AutomaticWater Entry system is for checking the
boiler level. It is composed of:
• level probe (short) (1) and safety probe (long) (2)in-
serted in the boiler, composed of a stainless steel rod;
• electronic control unit;
• hydraulic circuit controlled by a motor pump and so-
lenoid valve controlled by the electronic control unit.
When, during the normal operation of the machine,
the water level drops down, the level probe (1) sends a
signal to the electronic control unit, which activates the
motor pump and the lling solenoid valve, thus restoring
the level of water in the boiler.
If the level is very low or there is no water in the
boiler (during the machine's installation phase or due
to a failure), the safety probe (2) sends a signal to the
control unit which de-activates operation of 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 boiler.
To avoid possible ooding due to machine malfunc-
tions or leaks in the hydraulic circuit, the electronic
control unit includes a “Time-out” feature that cuts o
automatic lling after a maximum operating time.
During the installation of machines with three or four
groups the initial water lling time may exceed the estab-
lished time limit. In this event, just switch the machine o
and then back on to restore normal operating conditions.

2.6.8 Pressure switch
The machine includes two types of pressure switches:
COFFEE BOILER PRESSURE SWITCH
Each coee boiler is equipped with a pres-
sure switch to control the pressure.
The calibration is xed at 2 bars.
SERVICES BOILER PRESSURE SWITCH
The services boiler is provided with a
pressure safety switch which prevents exceeding the
calibration value.
The calibration is xed at 1.5 bars.
2.6.9 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 boiler due to
malfunction and chan-
nel it to the drain pad,
by means of a special
hose.
2.6.10 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 boiler services does
not exceed the value of 2.1 bar. In case of
malfunction, the valve can eliminate all the
excess pressure from the boiler.
The safety valve should be checked regularly as indicated in
Chapter"10.3 Maintenance" on page 48 ".
On all machines with 4 groups, two safety valves are installed.
2.6.11 Expansion - non-return valve
This is a valve consisting of an expansion valve and
a non-return valve.
• expansion valve (A):
the cold water sent from the pump to the coee boil-
ers is heated. This heating causes an increase in the
volume of water. To limit pressure
increases in the hydraulic circuit,
the valve limits the maximum in-
ternal pressure of the circuit to 12
Bar.
• non-return valve( (B):
its function is that of preventing
the backow of water from the cof-
fee boilers in the hydraulic circuit.
2.6.12 Safety thermostat
The thermostat allows to avoid damage to the heat-
ing element in case of lack of water in the boiler. The
thermostat bulb (3) is located inside a sheath (1) placed
at the center of resistance. The contacts of the thermo-
stat (4) are connected to the heating element (2). If the
heating element is exposed due to failure to load water
to the boiler, the temperature of the resistance increases
dramatically. At this point, the thermostat interrupts the
power supply to the resistance thus preventing damage.

2.6.15 Autosteamer (optional)
This system can be used for automatically heating and
foaming milk at the programmed temperature.
Below is listed its operating principle:
• select the desired key on the display, for example
;
• opening of the solenoid valve (2) with consequent
ow of steam from the boiler to the Autosteamer
nozzle (9);
• simultaneously, the system activates the air pump
(6) which is controlled by the control unit (3)and
powered by a processor (8). The regulation of milk
foaming can be made by changing the amount of air
intake operating the valve (5);
• after passing through the non-return valve (4), the air
mixes with the steam in the "Mixing interface" (11) ;
• leakage of steam from the nozzle (9);
• the probe (10) connected to the electronic unit of the
machine detects the temperature of the heating milk;
• Once the set temperature of the milk has been
reached, the electronic system blocks the ow of air
and steam.

2.6.16 Water lter
Mains water contains insoluble salts, which cause the
build-up of lime scale deposits in the boiler and other
parts of the machine.
Drinking water can also contain traces of heavy met-
als and substances, such as chlorine, harmful to health.
The lter makes it possible to eliminate or substan-
tially reduce the presence of these mineral salts.
The cartridge contained in the water lter must be
replaced at the frequency specied by the manufacturer.
For the water lter use and maintenance, follow the provisions in
par. "10.4 Water lter maintenance" on page 51.
2.6.17 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 chlo-
ride) or special water softening salt. It is very important
to regenerate the softener within the established times.
However, in locations where water is very hard, it will be
necessary to regenerate it more frequently. The same is
true of places in which there is a large consumption of
hot water for tea or other uses.
For the softener use and regeneration, follow the provisions in
par. "10.5 Softener regeneration" on page 53.
