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 ground coffee.
The dose weight of ground coffee.
The dispensing temperature.
The water dose.
For instant products
The dose weight of the instant products.
The drink temperature.
The water dose.
Should the standard settings need to be changed, pro-
ceed as indicated in the next sections of this manual.
The weight of instant products, the water dose and tem-
perature are directly controlled by the microprocessor.
To adjust them it is therefore necessary to follow the
programming procedures.
