2.6.1 Boiler
The boiler is constructed in copper sheet metal (1), to
which the heat exchangers are assembled which in turn
are connected to the dispensing group. Water for coee
dispensing is taken directly from the heat exchanger.
During dispensing, cold water is sent to the inside of the
exchanger by means of the motor pump. Inside the heat
exchanger, cold water and the pre-existing hot water
are mixed, thus obtaining optimal water temperature
for coee infusion.
2
1
ELECTRIC HEATING
The water is heated in the boiler by means of an electrical
heating element that is immerged in the water (2).
GAS HEATING
Gas heating is obtained by supplying the ame of the
burner located under the boiler
ELECTRIC + GAS HEATING
In machines equipped with both systems, it is possible
to combine the heating types.
2.6.2 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 channel it to the
drain pad, by means of a special hose.
2.6.3 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 "8.3 Maintenance" on page 34 ".
On all machines with 4 groups, two safety valves are installed.
2.6.4 Expansion + non-return valve
This is a valve consisting of an expansion valve and
a non-return valve.
t expansion valve (A):
the cold water sent from the exchanger pump to the
exchangers is heated.This heating causes an increase
in the volume of water. To limit
pressure increases in the hydraulic
circuit, the valve limits the maxi-
mum internal pressure of the cir-
cuit to 12 Bar.
t non-return valve (B):
its function is that of preventing
the backflow of water from the
exchangers in the hydraulic circuit.
2.6.5 Negative pressure valve
The purpose of the negative pressure valve
is to prevent the backow of liquids through the
steam nozzle when they are being heated. Fur-
thermore, the excess air is eliminated inside the
boiler during the heating phase of the machine.
2.6.6 Pressure switch
The pressure switch makes it possible to
control boiler pressure by activating or
bypassing the heating element in the boiler.
Any calibration of the pressure switch which
may be required can be carried out with the
machine in operation by means of the screw
(6) located on the body of the component.

2.6.7 LEVER groups
Lever groups us the boiler pressure and water. This
system does not require heat exchangers.
When the lever (1) is lowered, the spring (2) inside
the group is compressed: the piston (3) raises, allowing
water to enter the pre-infusion jacket.
When the lever is released, the piston compresses the
water to 8-10 bar, allowing dispensing of espresso coee.
The non-return ball valve (4) keeps water from owing
back into the boiler (5).

2.6.8 TOGGLE groups
For the toggle group is used a system similar to the
one shown for the Dispensing Group see par. "2.6.9
DISPENSING group" on page 13.
In this case the dispensing is controlled by a spring
system. The opening and closing of the valve for the
water ow is done by pressing a lever on the side of the
group that, in turn, moves a camme within the group,
allowing or not allowing the passage of water:

13 of 68
TECHNICIANS manual
ENGLISH
2.6.9 DISPENSING group
In this system, the dispensing group (1) is heated
by a thermosiphonic circuit (2) connected to the heat
exchanger (3). The same water is used for the coee
dispensing, thus ensuring the same temperature for all
coee servings:
t activation of the solenoid valve and of the pump
allow cold water to enter the exchanger (3) through
the injector (4);
t from the exchanger (3) the boiler water is carried to
the group (4) for dispensing;
t the pump allows the increase of the pressure of the
water ow up to 8-9 bar for dispensing.
The injector (4) and the ow reducer (5) are important
components for the operation of the dispensing group.
To increase the coee extraction temperature, remove
the ow reducer (5) or replace it with one of a larger
diameter. To decrease the temperature, replace it with
one of a smaller diameter.

2.6.10 Safety thermostat
The thermostat allows you to avoid damage to the
electrical resistance in case of lack of water in the boiler.
The thermostat bulb (7) is located inside a sheath (8)
placed at the center of resistance. The contacts of the
thermostat (9) are connected to the electrical resist-
ance (10). If the electrical resistance 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.

To reset the thermostat, press the center button (11). However,
before trying to operate the machine, verify the causes of the
blockade of the water feeding the boiler.
2.6.11 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.
2.6.12 Electronic control unit
The electronic control unit is installed
on EVD and DISPLAY versions.
Its purpose is to electronically control
the coee dose by means of the water
owing through the dosing device and to
check the lling of the water in the boiler.
Some versions of the control unit are
set up to be connected to the dispensing accounting
systems by means of a specic interface device.
2.6.13 Automatic Water Entry
The Automatic Water Entry system is for checking the
boiler level. It is composed of:
t probe inserted in the boiler (1) composed of a stain-
less steel rod;
t standard control unit (2) on EVD-DISPLAY versions,
electronic level regulator on the other versions (3);
t hydraulic circuit with a solenoid valve controlled by
the regulator.
The electronic control unit controls the level of water
in the boiler. When the level of water in the boiler drops,
the contact with the probe is interrupted. The control
unit sends and impulse to the entry solenoid valve and
to the motor pump, which act to restore the normal 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 certain time (2 minutes). The LED
(4) located on the front of the machine body comes on to
indicate activation of this system. During the installation
of machines with three or four groups the initial water
lling time may exceed the established time limit. In this
event, just switch the machine o and then back on to
restore normal operating conditions.

2.6.14 Volumetric dispensing
The volumetric dispens-
er installed on EVD-DISPLAY
versions serves the purpose
of measuring the quantity
of water sent to the group
for coee dispensing.
The dispenser generates
electrical impulses which
are sent to the electronic control unit.
These impulses are read by the control unit and
counted during the programming of the dose.
The ashing LED light (4) indicates that the electrical

2.6.20 Autosteamer (optional)
The "Autosteamer" system, supplied with certain ver-
sions with display, can be used for automatically heating
and foaming milk at the programmed temperature. Be-
low is listed the operating principle of the autosteamer:
t Press the appropriate button (1) placed on the base
to the left of the machine;
t opening of the solenoid valve (2) with consequent
ow of steam from the boiler to the autosteamer
nozzle;
t 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);
t after passing through the non-return valve (4), the air
mixes with the steam in the "Mixing interface" (11)
;
t leakage of steam from the nozzle (9);
t the probe (10) connected to the electronic unit of the
machine detects the temperature of the heating milk;
t Once the set temperature of the milk has been
reached, the electronic system blocks the ow of air
and steam.

2.6.21 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 indications
by the manufacturer.
2.6.22 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 res-
ins 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 impor-
tant to regenerate the softener within the established
times. The regeneration is to be done regularly every 15
days. However, in locations with very hard water, it will
be necessary to regenerate 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 indications by
the manufacturer.
