CHECKING AND ADJUSTING
THE MACHINE SETTINGS
To get the best results from the product used, the following
should be checked:
for coffee
That the used coffee dose is lightly compressed and damp.
The grade of grinding of coffee.
The weight of the ground coffee.
The dispensing temperature.
The water dose.
For instant products
The weight of the instant products.
The drink temperature.
The water dose.
Should the standard settings be varied, proceed as indi-
cated in the next sections of this manual.
The weight of the instant products, the water dose and
temperature are directly controlled by the microprocessor.
To adjust them it is therefore necessary to follow the
programming procedures.
