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. 18).
CUP SENSOR
The cup sensor is adjusted as to detect the presence of
objects (red LED glowing) placed between the sensor lens
and the reflector.
The green LED glows when the reading from the reflector
is correct.
The sensor's depth of reading is adjusted by turning the
trimmer (preset at the factory); the correct setting is ap-
proximately 30°, anticlockwise, from the maximum.
For correct operation, the infrared transmitter and the
reflector must be kept clean.
