Note
All the machines are equipped with automatic
water fi lling, and there is an automatic time control
device which allows the boiler to be fi lled with
water within a maximum period of time. This fun-
ction keeps water from coming out of the valve of
the boiler (flooding) and keeps the motor pump
from overheating.
If the maximum time is not enough for the boiler to
fi ll up completely, turn the machine off and then
back on, and repeat the operations described
above.

Attention
On the electrical mains, it is advisable to install a
main protection switch (A).
3.6. Turning the machine on
Turn the machine on using the main switch (
1
).
Before using the machine, wait for a short time (about
10 min.) until the gauge (
2
) indicates the correct wor-
king pressure (1-1.2 bars).

Attention
During the machine’s warm-up phase (roughly 20
minutes), the negative pressure valve will release
steam for a few seconds until the valve itself clo-
ses.
Before using the machine, run deliveries dry with
the fi lter holder attached for a few seconds to
release any air which may be in the circuit, so that
the delivery groups are completely heated.
Before using the machine, dispense a few ser-
vings of coffee to check the operating pressure of
the machine.
