7. MAINTENANCE AND CLEANING
7.1 Safety precautions
Carefully read the instructions provided in chapter "I. SAFETY
PRECAUTIONS" on page 33.
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 Qualied 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 coee 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 lters. Check for any damage on the edge of
the lters and check whether any coee grounds settle in the coee cup
and replace lters and/or lter holders, as required.
X
GRINDER-DOSER
Check the ground coee 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 Qualied Technician
to replace the at grinders after every 400/500 kg of coee. For conical
grinders, replace every 800/900 kg.
X
WATER FILTER
SOFTENER
Carry out the water lter cartridge replacement or the water softener
regeneration with frequency specied by the manufacturer.
X
GAS SYSTEM
Check for the presence of possible gas leaks, by spreading a soapy solution
on the pipes.
X
BOILER
Request the intervention of the Technical Assistance 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 Qualied 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
Qualied Technician must replace all the water contained
in the hydraulic circuits as indicated in par. "7.2 Periodic
maintenance" on page 54.
Furthermore, all operations planned for the periodic
maintenance must be carried out, see previous para-
graph.
