WEEKLY CLEANING
OF THE BREWER UNIT
On a weekly basis, besides cleaning the external parts of
the brewer unit to remove any powder residue, especially
in the area of the funnel, also the parts of the unit which
come into contact with the drink should be sanitised.
These operations must be carried out with the power
switched off.
- Undo the fastening screw and remove the cover to
access the brewer unit.
- Disconnect the hose from the mixer and remove the
mixer (9-1) from the brewing cylinder.
- Disengage the cylinder from the assembly by pulling the
release lever (9-2) and slide it out of the piston control
fork (9-3) by pulling it outwards.
- Slide out the piston from the cylinder.
- Extract the sliding filter holder (9-4) from the guide (9-
7) releasing the link (9-6) from the stop lever (9-5).
- Extract the scraper assembly (9-8).
- Wash all parts with mild detergent, being sure that all
visible residue and product layers are mechanically
removed, using a brush if necessary.
- Soak them for approx. 20 minutes in a container filled with
a chlorine-based detergent similar to the one used for the
mixers.

Do not use screwdrivers or any other sharp objects
against the filter holder seal and do not place the seal
on surfaces which may damage it.
If the metal filter is clogged, it should be replaced or
cleaned with a specific product.
To remove the metal filter, first pull out the seal from its
edge (see fig. 10).
The filter must be cleaned at least every 2,500 selections.
To reassemble the brewer unit follow the above instruction
in the reverse order, making sure that the seal is installed
before the filter.
REPLACING THE FILTER CARTRIDGE
Every 30,000 drink selections or every 6 months, the
mains metal filter cartridge should be replaced according
to the procedure described in section "Installing the filter
cartridge".
SUSPENDING FROM USE
If for any reason the machine is switched off for a period
exceeding the use-by date of the products, the following will
be necessary:
- completely empty the containers and thoroughly wash
them with the chlorine-based detergents used to clean the
mixers.
- completely empty the air-break and the instant product
boiler, loosening the clamp on the hose.
Before reinstating the machine, the cleaning and
sanitising procedure described in the section "Yearly
sanitising" should be carried out.
