MAINTENANCE AND CLEANING

Safety precautions

7.1
Carefully read the instructions provided in chapter "I. SAFETY
PRECAUTIONS" on page 25.

Periodic maintenance

7.2
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
GAUGE Keep the boiler pressure between 0,08 and 0,14 MPa (0,8 and 1,4 bar).
Periodically check water pressure during coffee delivery: check the pressure in-
GAUGE
dicated on the gauge, which must be between 0,8 and 0,9 MPa (8 and 9 bar).
Check the condition of the filters. Check for any damage on the edge of
FILTERS and PORTAFILTERS the filters and check whether any coffee grounds settle in the coffee cup
and replace filters and/or filter holders, as required.
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-
GRINDER-DOSER
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.
WATER FILTER Carry out the water filter cartridge replacement or the water softener
SOFTENER regeneration with frequency specified by the manufacturer.
Request the intervention of the Maintenance Technician at least every
BOILER
three months to carry out the replacement of the water in the boiler.
Problems to the components highlighted in grey require shutting
down the machine and the intervention of the Maintenance
Technician.
USER manual
