STANDARD SETTINGS
The vending machine is supplied with the following set-
tings:
- tea temperature (at the spout) approx. 85÷89° C;
- instant product temperature (at the spout) approx. 75° C;
- operating pressure 4 bar max.
ADJUSTING THE BREWING
CHAMBER VOLUME
When the upper piston is correctly positioned, the coffee
unit can operate with coffee doses of 5.5 to 8.5 g.
To change the piston position (see Fig. 17) do as follows:
- remove the snap ring from its seat;
- place the piston in the appropriate adjusting notches:
.less deep notches for 5.5 to 7.5 g doses;
.deeper notches for 6.5 to 8.5 g doses.
ADJUSTING THE GRADE OF GRINDING
When a variation in the grade of grinding is desired, turn
the relevant adjusting knob on the grinder (see Fig. 18)
and more specifically:
- turn the knob anticlockwise for coarser grinding;
- turn the knob clockwise for finer grinding.
For optimum results, it is advisable to vary the grade of
grinding with the coffee grinder motor running.

N.B.: After adjustment of the grade of grinding, at least
2 test selections must be performed in order to check
the new grade of the ground coffee:
the finer the grade of grinding the longer the time neces-
sary for dispensing the coffee and vice versa.
ADJUSTING THE COFFEE DOSE
The dose adjusting lever can be positioned in one of the 6
reference notches bearing in mind that:
- the dose is increased by lifting the lever:
- the dose is reduced by lowering the lever:
- every notch changes the dose by approx. 0.25 g.
In addition, when the lever is fully rotated upwards, the
ratchet can be released from the groove in the dose
regulator (see Fig. 15) and replaced into a different groove
to change the average dose setting to:
- low 6 g. ± 0.5
- medium 7 g. ± 0.5
- high 8 g. ± 0.5
To take the dose just remove the coffee unit and press
button "2" from of the "maintenance" menu (see relevant
section).
Important notice!!!
To refit the coffee unit, pay special attention to the
piston position. Reference notches on the external
disk and on the unit case should match (see Fig. 19).
WATER TEMPERATURE CONTROL
If requiring to change the boiler temperature, adjust the
special trimmer (see Fig. 22) keeping in mind that:
- tightening will increase the temperature;
- loosening will decrease the temperature;
- the temperature varies by approx. 1° C every 2 turns.
