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 turn-
ing on the electronic protection.
If this should happen, just turn the machine off
and then start it up again to complete its loading
procedure (see chapter “MACHINE
FUNCTIONS MESSAGE – LEVEL ERROR”).
To fill the boiler manually for the first time, pro-
ceed as follows:

will enter the boiler;
RQFHWKHPD[LPXPOHYHOKDVEHHQUHDFKHG
as indicated by the optical level, turn tap “A”
off;
VZLWFKWKHPDFKLQHRQE\SODFLQJWKHJHQ-
eral 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, accord-
ing to the various functions and needs of the
coffee desired, proceed as follows:
