to the established level.
When the filling process is complete, the water
will start to heat up and the correct operating
temperature and pressure will be established.
Pump pressure adjustment:
The pump comes with a factory-programmed

proceed as instructed below:
Remove the plastic cap, located on the side
panel of the machine, and use a screwdriver to
turn the screw of the pump.
By turning it clockwise the pressure will
increase.
By turning it anti-clockwise the pressure will
decrease.
Expansion valve adjustment: The expansion valve
is a component that limits the maximum pressure

must never exceed 12 bar. The valve is factory-
programmed at 11 bar. If you wish to adjust the
valve, follow the indications below:
Place the filter holders with the blind filter in the
coffee group.
Set the group running and adjust the pump to
the pressure at which you wish to use the valve.
Then turn the valve adjuster until water starts
coming out of it.
When the process is complete, adjust the

If the coffee comes out very quickly or
very slowly, change to a finer or coarser
coffee grind and experiment with
compactness to suit preference.
1. The machine must be connected. Place the
filter holder (with filter) in the group.
2. Press the XL button (continuous coffee

dispenser) and allow water to pass through
the group. Performing this procedure before
making coffee will eliminate residues and
establish the temperature for optimal service.

4. Clean the coffee residues that have been
deposited on the edges of the filter to ensure a
perfect fit.
5. Fit the filter holder in the group and turn from
left to right, exerting sufficient pressure at the
end.
6. Place the cups or cup on the tray and press the

General tips
The filter holder must always be fitted in the
machine to keep it warm.

To program different coffee doses, follow the
instructions below:
1. .HHS WKH XL button pressed down for at least
3 seconds, until the LED starts blinking (the
other LEDs remain off).
2. Before 5 seconds have passed, press the
button of the dose to be programmed. The LED
will remain steadily lit, as will the programming
button (XL). The pump and solenoid valve are
activated at this time.
3. When the cup contains the required amount of
coffee, in order to stop dispensing, press the
dose button that was used for programming
once again, or press the XL button.
4. When the XL button stops blinking, the dose
has been memorised.
To change or program different doses, follow the
above steps and apply them to the dose to be
changed.
Continuous dispensing:
Press the XL button to obtain coffee in semi-
automatic mode. Pressing the XL button activates
dispensing until the button is pressed again
to complete the process. The maximum time

will stop.
Remember: Programming of the left-
hand group is transferred to the other
groups, which may be modified as
required.
VERY IMPORTANT: Never remove the
filter holders while the coffee group
is running.
Programming the pre-infusion function
The pre-infusion function allows a quantity of water
to penetrate the filter holders for 2 or 3 seconds,
thus moistening the tablet of ground coffee,
causing it to swell and opening up irrigation
channels through it.

The coffee machine is supplied with the pre-
infusion function deactivated.
If you wish to activate pre-infusion, follow the steps
below:
1) With the machine off (general OFF switch),
keep the single espresso coffee (S) button on
the left button pad pressed down, and start
the machine (general ON switch) until only the
button being pressed remains lit.
2) Switch the machine off and then switch it back
on again.
3) The pre-infusion function is now activated.
To deactivate the pre-infusion function, follow
the same steps but press the single lungo coffee
(L button).
IMPORTANT: The pre-infusion function
can only be enabled for a single
espresso (S) and a single lungo (L).

water to come out of the nozzle after setting the

that you place the nozzle in the drainage tray.
