Victoria Arduino BLACK EAGLE VA388 User Manual

The infusion unit of the VA388 is different from
common systems with thermosiphon circulation.
In this case in fact the temperature of the unit
is ensured by the presence of a 300 W heating
elements cartridge that lights up based on the
needs assessed from time to time by the tem-
perature probe located on the upper side.
In unit section shows:
A Group heating elements housing
B water supply into the unit
C pre-infusion chamber
D water outlet
The unit VA388 uses also a pre-infusion cham-
ber to increase the time in which water without
pressure wets the capsule in order to provide a
uniform extract.
Since this is a machine created for international
competitions, it comes equipped with a cylinder,
which limits the space and the loss of water after
the group is drained.
Water enters the unit (B), fills the pre-infusion
chamber in about 3 seconds (C). In the mean-
time the capsule is reached by the water (D) and
is naturally wet. Once the chamber is filled and
the delay filled, the pressure of 9 bar reached the
coffee initiating the extraction into the cup.
Once the machine is turned on the temperature
of the unit can be viewed on the screen or in the
descriptive programming pages using the navi-
gation menus.
NOTE
The screen can only display the temperature
of the groups.
