Sezione 15 Part 15. Ordinary and prevention maintenance
15.1 Monthly maintenance
15.1.1 Disinfecting of components in contact with
ingredients
These operations must be carried out once a month to ensure the hygiene of the machine. These
operations have already been described in the paragraph "Cleaning and Disinfecting of
components in contact with ingredients".
15.1.2 Adjustment of the solenoid valves of instant
ingredients
The presence of lime scale can affect the correct operation of the solenoid valves of the instant
ingredients. During vending, check that the water flow from each solenoid valve is more than
sufficient to completely rinse the corresponding mixing bowl at the end of one selection. If the flow
is limited, turn the adjustment screw of the solenoid valve.
15.1.3 Adjustment of grinding
This section is for
Versions
E
only.
The brewing time for a 50 ml espresso coffee must be around 20
sec. If, due to the wear and tear of the grinder, the brewing time is
shorter, turn the adjustment ring nut of the grinder by 1-3 steps in the
direction indicated by the sticker near the grinder itself. A thinner
grinding and therefore, an adequate brewing time is then obtained.

lubricated:
