The ground coffee is fed into the dosing apparatus, which ac
-
cumulates ground coffee up to a certain level. When the level is
reached the electromagnetic valve opens and the accumulated
dose of coffee is sent to the espresso group.
The dosing apparatus helps you set the required amount of cof
-
fee for the espresso group according to the desired drink. The vol
-
ume of coffee is regulated with the help of the dosing apparatus’s
cam (see fig.4.6 pos.2 and fig.4.7). The positions can be from
1
to 6 (MAXIMUM)
. At the same time it is prohibited to set the cam
to positions
5 or 6 without increasing the volume of the boiling
chamber (see further)! THIS CAN DAMAGE THE ESPRESSO
GROUP!
