PRESSURE GAUGE
Keep checking the heating unit pressure which must be between 0.08 and
0.14 MPa (0.8 and 1.4 bar).
X
PRESSURE GAUGE
Periodically check the water pressure when coee is being dispensed:
check the pressure indicated on the gauge, which must be in the range of
0.8 to 0.9 MPa (8 and 9 bar).
X
FILTERS and PORTAFILTERS
Check the condition of the lters. Check for any damage on the edge of
the lters and check whether any coee grounds settle in the coee cup
and replace lters and/or lter holders, as required.

GRINDER-DOSER
Check the ground coee dose (between 6 and 7 grams per time); check
the degree of grinding. The grinders must always have sharp cutting
edges. Their deterioration is indicated by the presence of too much
powder in the grounds. We recommend calling the Qualied Technician
to replace the at grinders after every 400/500 kg of coee. For conical
grinders, replace every 800/900 kg.

every three months to replace the water in the heating unit.
X
DRIP TRAY
