BEZZERA MATRIX-DUO
MOD.
For washing and cleaning, do not use solvents,
detergents or abrasive sponges. Only use specific
products for coffee machines. Wash the bodywork
using a cloth soaked in water and/or neutral de-
tergent, taking care to dry the surface well before
reconnecting the machine to the mains electricity.
Use water to wash the cup rack and the drip tray.
To wash the tank after having extracted it, use wa-
ter and neutral detergents and perform thorough
rinsing. Reinsert the tank and the silicon tubes.
6.3 Hydraulic circuits cleaning after
prolonged use
Once the hydraulic/electrical installation has
been completed, carry out a complete rinsing cy-
cle following the operations described in points
A and/or B.
Warnings: for use of the machine controls (valves,
dispensing group, switches, etc.) refer to the rela-
tive sections contained in this manual.
The introduction into the tank of chemicals, des-
caling agents, vinegar and/or even citric acid,
even if diluted, compromises the life of the ma-
chine components. Any product used that is not
fresh water will automatically void any warranty.
Use ideal hardness drinking water, in French de-
grees approximately 6°F; never use hot water.
A - Upon initial ignition or after a prolonged pe-
riod of inactivity of the machine (approximately 7
days)
1) Machine ignition, boiler water supply and heat-
ing as described in sections 5.1 and 5.3.
2) Wait 12 hours.
3) Perform dispensing of at least 30 seconds with
the filter-holder connected but without coffee to
allow the exchange of water in the exchanger
(the lever machines need coffee inside the filter-
holder).
4) Turn off the machine and completely drain the
water into the boiler by operating the water and
steam tap into a heat-resistant container with a
capacity of at least 1 litre.
Ensure that:
- there is always fresh water in the tank (where
required).
- do not re-use the water drained during rinsing.
B - After a stop of at least 4 hours
1) Dispense water from the respective tap for 5
seconds.
2) Perform dispensing of at least 15 seconds with
the filter-holder connected but without coffee.

6.4 Screen cleaning

In order to clean the front of the machine and
in particular the TFT touch screen, a function of
inhibiting the touch function has been provided to
allow the screen area to be cleaned with a damp
cloth.
To activate this function it is necessary to:
1) Open the drop-down menu.
2) Touch the screen cleaning icon.

The entire area of the screen will remain inhib-
ited for approximately 10 seconds; if more time is
needed, repeat the operations described above.
