MAINTENANCE AND CLEANING
7.1
Safety precautions
Carefully read the instructions provided in chapter "I. SAFETY
PRECAUTIONS" on page 25.
7.2
Periodic maintenance
Besides carrying out the maintenance activities ac-
cording to the frequency indicated in the table, must
get a general check by a Maintenance Technician at least
once a year.
Component Type of intervention Weekly Monthly Quarterly
GAUGE Keep the boiler pressure between 0,08 and 0,14 MPa (0,8 and 1,4 bar).
X
GAUGE
Periodically check water pressure during coffee delivery: check the pressure in-
dicated on the gauge, which must be between 0,8 and 0,9 MPa (8 and 9 bar).
X
FILTERS and PORTAFILTERS
Check the condition of the filters. Check for any damage on the edge of
the filters and check whether any coffee grounds settle in the coffee cup
and replace filters and/or filter holders, as required.
X
GRINDER-DOSER
Check the ground coffee 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 pow-
der in the grounds. We recommend calling the Maintenance Technician
to replace the flat grinders after every 400/500 kg of coffee. For conical
grinders, replace every 800/900 kg.
X
WATER FILTER
SOFTENER
Carry out the water filter cartridge replacement or the water softener
regeneration with frequency specified by the manufacturer.
X
BOILER
Request the intervention of the Maintenance Technician at least every
three months to carry out the replacement of the water in the boiler.
X
Problems to the components highlighted in grey require shutting
down the machine and the intervention of the Maintenance
Technician.
7.3
Maintenance after a brief period of
machine inactivity
"Short machine downtime" refers to a period of time
exceeding one working week.
If the machine is reactivated after this period, the
Maintenance Technician must replace all the water con-
tained in the hydraulic circuits as indicated in par. "7.2
Periodic maintenance" on page 41.
Furthermore, all operations planned for the periodic
maintenance must be carried out, see previous para-
graph.
