3.5.2. Spring-loaded safety valve
In the case of irregular operation in the control of heating elements, the safety valves guarantee the integrity of
the boiler, releasing excess pressure and keeping it from going over 0.18 MPa.
The safety valves are manufactured under strict quality control standards and following very demanding technical
criteria. Once checked by the manufacturer, they are immediately sealed.
3.5.3. Pressure relief valve (anti-vacuum valve)
This valve, located on the boiler, prevents the depressurization of the boiler interior, keeping liquids from being
sucked in through the steam ejectors.
3.5.4. Automatic water fi lling device
The machine has a level sensor (a stainless steel strip that is in contact with the water inside the boiler). The
sensor is connected to a control processing unit (CPU) which permanently indicates the water level. When the level
is low, the CPU activates the pump and the solenoid valve, allowing water to be fed in until the sensor indicates
that it has reached the optimum level.
3.5.5. Visual level (Optional)
The water level can be checked at any time via the water level viewer (22).
3.5.6. Flow control valves

3.6.
The pump/motor starts up when any button on the button pad is pressed, increasing the pressure up to the 0.8/0.9
MPa necessary to prepare the coff ee. The pump/motor are also controlled by the automatic level control device,
which keeps the boiler fi lled with water.
In order to regulate the pump pressure, proceed in the following manner: loosen the lock nut, which holds the
adjustment screw. Loosen the screw to reduce the pressure, or tighten it to increase it. When the operation is
complete, make sure the lock nut is tightened once more.
