Fig. 3 - AV model available with 

1, 2, 3 and 4 groups

General Description

The AV model machine is built in the 1, 2, 3, and 4 group versions and is 

essentially composed of the same parts as EE model.

This model differs from EE model in that it allows the operator to choose 

four different quantities of water for brewing coffee. Each group, there-

fore, is provided with a 5 button control panel, allowing a combination of:

- a quantity of water for one normal espresso coffee;

- a quantity of water for one tall coffee;

- a quantity of water for two normal coffees;

- a quantity of water for two tall coffees.

The fifth button is used to program the other ones, as we shall see later,

and as an on-off switch for continuous brewing.
