8 - Start-up
IMPORTANT!
Before turning on the machine, be sure to check Sections 5 and 6 of this Manual.
Set the main switch (1) to the "ON" position and automatically the machine will proceed
to fill the boiler to the set level. Once the filling process has been completed, the water
will be heated up to the working temperature and pressure.
Pump pressure regulation (PLUS model):
The pump is factory-set to 9 bar pressure. If it is
necessary to adjust it, proceed as instructed below:
1. Remove the plastic cap located on the side panel
of the machine.
2. With the help of a screwdriver, turn the pump screw.
In a clockwise direction, the pressure is increased.
Counter clockwise decreases the pressure (see
Diagram 3).
3. Check the pump pressure on the pressure gauge
(4) located at the front of the machine.
Regulation of the OPV valve (working pressure of the
coffee pump in the ZERO model):
The OPV valve (15) is a component that regulates the maximum operating pressure of
the machine when making coffee. This pressure should
never exceed 12 bar. The valve is regulated at 10 bar in
the factory. If you need to change it, follow the instructions
given below:
1. Fit the filter holder fitted with the blind filter in the
coffee group.
2. Start the group up and turn the regulator of the OPV
valve (15) until the reading on the pressure gauge (4)
has reached the required figure. Turning the regulator
to the right increases the operating pressure, and to
the left the pressure decreases (see Diagram 3).
From this moment, it will be necessary to wait until the
temperature of the coffee group reaches the set point (shown in the specific display
of each group (3) dedicated to the temperature) in order to start making coffee, and
until the temperature of the steam/hot water boiler reaches the set point (the pressure
