47) Water drainage system
49) Solenoid valve
The feed unit consist of a hot press brass block in which the infusion chamber has been set.
Pressing the coffee feed button turns on the pump (29) and activates the solenoid valve (49).
2.5.- BOILER
50) Feed unit
52) Injector
53) Heat exchanger
This boiler is made of copper and is intersected by a heat exchanger (53) which is connected
to the feed unit (50).
During the feed cycle cold water is sent into the exchanger through the use of a pump
and injector (52). Between the heat exchanger (53) and the feed unit (50) a thermo siphon
circulation is established, through the difference in temperature and the density of water
which maintains the unit and the correct temperature needed for making the coffee.
A thermostat (61) controls the temperature of the heating element inside the boiler, in order
not to pass over the correct rate. In this case the machine turns off. To be turned on press the
resent button located on the thermostat.

2.5.1.- SPRING LOADED SAFETY VALVE
In the case of anomalies in the heating control pressure system the spring loaded safety valve
(31), located on the boiler guarantees the integrity of the boiler by releasing the excess
pressure when the boiler reaches 1.8 bar.
The safety valves are manufactured under strict conditions and respect severe technical
criteria, they are sealed after testing in the factory.
