General Description
The model AV machine is built in the 1, 2, 3, and 4 group
versions and is essentially composed of the same parts as
model EE.
This model differs from model EE in that it allows the ope-
rator to choose four different quantities of water for bre-
wing coffee. Each group, therefore, is provided with a 5
button control panel, allowing a combination of:
- a quantity of water for one normal (short) 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 bre-
wing.
