If it is necessary to change the grinding degree, act on
the corresponding coffee-grinder knob (see fig. 24) and
more precisely::
- turn counterclockwise to obtain a coarser grinding
degree;
- turn clockwise to obtain a finer grinding degree.
It is recommended to vary the grinding degree during the
operation of the coffee-grinder motor.
Please Note: after having changed the grinding
degree, make at least 3 selections to check the new
granulometry of ground products more carefully:
he finer the grinding degree, the longer the time required
to dispense the coffee drink and viceversa.
after the regulation, please check the quantity of ground
coffee that may slightly vary.
the regulation knob can be easily removed from the
grinder to avoid unintentionally varying the grinding
degree.
the knob shall be kept in the proximity of the machine
for any subsequent operation.
coFFEE doSE rEgULatIoN
a sensor is arranged on the grinder to count the rota-
tions of the grinding wheels.
this will enable the software intended to control the
machine to establish the number of turns and, therefore,
the number of coffee grams associated with every single
selection.
Follow the programming procedures to establish how
many grams of ground product shall be associated with
every single selection.
Please Note: before programming coffee doses, use the
doser setup function to define the flow rate in gr/s.
To take the dose, just remove the coffee unit and select
the corresponding item from “special functions” of the
“Technician” menu (see the relative paragraph).
Important!!!
To reassemble the coffee unit, pay great attention
when positioning the piston.
