SANITISING THE FOODSTUFF
CIRCUITS AND THE MIXERS
When installing the unit, and then at least once a week or
even more frequently according to the use of the machine
and the quality of the inlet water, the mixers and the
dispensing conduits must be thoroughly sanitised (cleaned
and disinfected), to guarantee proper hygiene of the dis-
pensed products.
In order to make sanitising operations quicker, some
spare parts, which can replace the parts to be cleaned,
are supplied with the machine.
The parts to be cleaned are as follows:
- mixer and instant drink dispensing conduit;
- coffee dispensing spout;
- cup chute;
- dispensing compartment;
- remove the covers, the powder and the water funnels, the
feeders, the powder deposit drawers and the mixer wheels
from the mixers (see Figure 6);

Fig. 6
- a splash guard ring is also fitted in the fresh coffee and
milk mixers; this must be cleaned and then replaced in
the same mixers;
- in order to remove the wheels, block the disk fitted on the
mixer shaft with a finger (fig. 7);
- wash all parts with detergent being sure that all visible
residue and product layers are mechanically removed,
using a brush if necessary;
Disinfection should be carried out using chlorine-based
detergents;
- soak all components for approx. 20 minutes in a container
filled with the previously prepared chlorine-based deter-
gent;
- reinstall the feeders and the water funnels;
- reinstall the powder deposit drawers and the powder
funnels after thoroughly drying them.
After reinstalling all parts the following is however
required:
- enter into "Filler" mode to clean the mixers (see relevant
paragraph) and add a few drops of the chlorine-based
detergent in the various funnels
- After disinfection thoroughly rinse all components to
ensure that all residue of the detergent solution is re-
moved.
All operations requiring the machine to be energized
should be carried out by qualified personnel ONLY,
informed about the specific risks of such situation.
Some models, with the fresh product being dispensed
directly into the cup, are fitted with a special spout (see
fig. 8), as alternative to the splash guard ring, preventing
the pressure created by the brewer piston from being
discharged into the cup.

Also this spout and its plug must be cleaned following the
same procedure indicated for the mixers.
