5. ADJUSTMENTS TO BE MADE BY A QUALIFIED TECHNICIAN ONLY
NOTE: this operation must be carried out with
the machine turned off.
All models are equipped with a
level gauge to keep the water level inside the
boiler constant.
When using the machine for the first time, it is
advisable to fill the boiler by hand to avoid
damaging the electrical resistor and turning on
the electronic protection.
If this should happen, just turn the machine off
and then start it up again to complete its loa-
ding procedure (see chapter “MACHINE
FUNCTIONS MESSAGE – LEVEL ERROR”).
To fill the boiler manually for the first time, pro-
ceed as follows:
• remove the worktop grid;
• turn the manual “A” level tap so that water
will enter the boiler;
• once the maximum level has been reached,
as indicated by the optical level, turn tap “A”
off;
• switch the machine on by placing the gene
ral switch on “I”; this will activate the level
gauge which will automatically maintain the
water level inside the boiler.
NOTE: this operation can be carried out while
the machine is turned on.
To adjust the service pressure of the boiler,
thus regulating the water temperature, accor-
ding to the various functions and needs of the
coffee desired, proceed as follows:
• remove the worktop grid cover;
• remove the protective metal sheet by
unscrewing the two side screws (A) as
shown in the following illustration;

ADJUSTMENT
• turn the pump registration screw, turning it
clockwise to INCREASE and counter clock
wise to DECREASE the pressure.
• The set pump pressure is shown on the
lower part of the gauge.
Once the adjustment operation has been com-
pleted, screw the protective metal sheet back
into its setting and replace the worktop grid
cover.
• turn the pump registration screw, turning it
clockwise to INCREASE and counter clock
wise to DECREASE the pressure.
Advisable pressure: 1 - 1,4 bar
(according to the kind of coffee).
Advisable pressure: 9 bar.
