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 coee
dispensing, thus ensuring the same temperature for all
coee 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 coee 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.
