CHECKING AND ADJUSTING
THE MACHINE SETTINGS
To get the best results from the product used, the following
should be checked:
- That the used coffee dose is lightly compressed and
damp.
- The grade of grinding of ground coffee.
- The dose weight of the products.
- The drink temperature.
- The water dose.
Should the standard settings need to be changed, proceed
as indicated in the next sections of this manual.
The dose weight of 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.
SETTINGS
The vending machine is supplied with the following set-
tings:
- coffee temperature (at the spout) approx. 85-89"C
- instant product temperature (at the spout) approx.
75"C
The machine standard settings assign the same price,
expressed in number of basic coins, to all selections.
WATER TEMPERATURE CONTROL
The boiler temperature is controlled by the software (92"C
by default) and can be adjusted directly from a menu.
IDENTIFICATION OF THE BREWER UNIT
Some adjustments and/or setting changes are specific to
the espresso unit installed in the machine; before proceed-
ing to any adjustments and/or settings it is indispensable
to identify the type of brewer unit installed.
To identify the brewer unit refer to the diameter of the
brewing chamber (see fig. 19).
Standard brewer unit
It has a brewing chamber with diameter of 37 mm; the unit
operates with coffee doses between 5.5 and 8.5 gr.
Large brewer unit
It has a brewing chamber with diameter of 45 mm; the unit
operates with coffee doses between 5.5 and 8.5 gr.
It is possible to use a layout with double dose release.
In this case the dose will have to be 6 gr maximum (for a
total of 12 gr); greater doses can jam the brewer unit.
