located inside a sheath placed
at the center of resistance.The contacts of the thermostat
(13) are connected to the electrical resistance (8).
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.
5Delivery group
The delivery group is composed as follows :
the group body (• 1) is made up of a metallic block
which is hooked onto the coee boiler (2);
the activation of the motor pump and solenoid valve•
(3) located on the side of the group allows the cold
water to enter the boiler (4), consequently the hot
water in the boiler is carried towards the delivery
group (5);
the electrical cartridge heating element (• 6) 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 (• 7) detects the value of the
temperature of the group and sends it to the elec-
tronic control unit;
the activation of the safety thermostat (• 8) prevents
risks if there is a failure in the electronic system.

6Automatic Water Entry
The Automatic Water Entry system is for checking the
boiler level. It is composed of:
level probe (short) (• 1) and safety probe (long) (2)
inserted in the boiler, composed of a stainless steel
rod;
electronic control unit (• 3) ;
hydraulic circuit controlled by a motor pump and•
solenoid 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 (3), 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 or due to a
failure), the safety probe (2) sends a signal to the control
unit which de-activates 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 flooding due to machine
malfunctions or leaks in the hydraulic circuit, the
electronic control unit includes a timing device that cuts
o automatic lling after a maximum operating time
(roughly 30 seconds). 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.

8Volumetric dosing
The volumetric dosing device serves the purpose of
measuring the quantity of water sent to the group of
espresso delivery.
The dosing device generates an electrical impulse
which is sent to the electronic control unit.
This impulse is read by the control unit and memorized
during the programming of
the dose.
The ashing of the LED (1)
indicates that the electrical
impulse has been sent from
the dosing device to the
control unit.

7Pumping system
This is a component that feeds
the machine, raising the water
pressure to 8-9 bar for coffee
delivery and automatic lling of
the boiler.
9Electric control unit
The electronic control unit (1) is the core of the
machine. It monitors and controls all operation of the
unit.
Among its functions, it electronically manages the
dose of coffee through the passage of water in the
dispenser and controls the entry of water into the
boiler.
It is set up to be connected to the delivery accounting
systems by means of a specic interface.
The information concerning the installed software
(date and version) can be seen on the display when the
machine is turned on.

12 Softener
Mains water contains insoluble salts, which cause the
build-up of lime scale deposits in the boiler and other
parts of the machine. The softener makes it possible
to eliminate or substantially reduce the presence of
these mineral salts. The resin softener 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. The regeneration is to be done
regularly every 15 days. However, in locations where
water is very hard, it will be necessary to regenerate
it more frequently. The same rule can be applied to
locations where there is a large consumption of hot water
for tea or other uses.
12.1 Regeneration of the softener
Proceed as follows:
move levers (• B) and (E)
from left to right;
remove the lid by loosen-•
ing the knob (A);
release enough water•
through the pipe (C) to
make room for the salt to
be added, based on the
model (see the table on
the following page);
clean any salt or resin residues from•
the gasket located on the cover;
put the cover back in place by screw-•
ing the knob (A) down securely and
move the lever (B) back from right
to left;
let the salt water drain from the little•
hose (D) until the water is no longer
salty (about 30-60 minutes). The salt
allows the accumulated mineral
salts to be released;
switch the lever (• E) from right to
left back to its initial position.
