Nuova Simonelli PRONTOBAR - Calibration Procedures

2.3 CALIBRATION
The next installation phase involves setting the
grind, the cappuccino air and the milk flow.
These can also be made when the machines is
turned on.
2.3.1
RIGHT GRINDER ADJUSTMENT
To adjust grinding fineness on the right grinder,
use a 3 mm allen key.
Turn clockwise to increase fineness and anti-
clockwise to reduce it.
When adjusting for finer grinding, we recommend
tightening by a maximum of two turn and then
testing the effect by pouring at least two cups of
coffee.
Fineness adjusting will be effective as the previ-
ously grinded powder will leave the grinder.
2.3.2 LEFT GRINDER ADJUSTMENT
To adjust grinding fineness on the left grinder,
use a 3mm allen key.
Turn counter clockwise to increase fineness and
anticlockwise to reduce it.
When adjusting for finer grinding, we recommend
tightening by a maximum of one turn and then
testing the effect by pouring at least two cups of
coffee, the first of which should be poured using
the previous grinding setting.
ESPRESSO: delivery time (from pushing the
button and the finish of brewing) must be set
around 25–30s; adjust finer (2 by 2 turn) to
increase the delivery time to obtain a more tasty
espresso, with darker and thicker cream and
stronger body. If regular coffee is your major
product and only one grinder is set to be used for
both espresso and regular coffee, it’s possible to
modify the product delivery time by adjusting the
grinding time.
COFFEE: delivery time (from pushing the but-
ton to the end of brewing) must be set around
25–30s; adjust finer (1 by 1 turn) to increase the
delivery time to obtain a more tasty coffee, with
darker and thicker cream. If you use one grinder
for regular coffee, set TAMPING ‘yes’ and grind-
ing adjustment coarser (this will give you a better
taste and longer life of the blade), if you use only
one grinder for espresso and regular coffee and
espresso is your major products, set TAMPING
‘no’ and play with the grinding time to modify the
delivery time.
