9. ADJUSTMENT AND SETTING OF THE
DOSE
It is possible to adjust the dose only on E models.

9.1. Adjusting the dose

The coffee dose adjustments are made by acting on
the group keyboads with machine at rated pressure.
1 Press the button E on any button panel and hold
it down for 8-10 seconds until water stops flowing
from the dispensing unit and the led of the con-
tinuons button on the first button panel on the left
begins flashing.
2 It is necessary to act as to make 1 or 2 cups in
order to reach the correct coffee amount adjust-
ment in the cup.
3 Put the filter-holder (with ground coffee) on the left
unit and the cup under the spout.
4 Operate the selected button (i.e. button A for one
small cup).
5 One the required coffee amount in the cup has
been reached, press the stop button E. Coffe will
stop pouring and the microprocessor will store the
dose.
6 Press the continuous button E again; the led will
go out and the machine will store the new quantity.
7 Make the coffee and check the cup amount in order
to check that programming is correct.
If some doses have to be changed (B-C-D), once
at point 5 repeat the instructions in points 3-4-5 for
each dose, remembering to use the filter-holder with
relevant filter and freshly ground coffee.
Then carry out point 6 and repeat point 7 to check
all changed doses.
If all units are to be programmed with the same
doses,the selection of coffee doses is finished. If
the dosage of another unit is to be changed (1-2-3-4
doses), proceed as indicated in the above-mentioned
point 1-7,using only the button panel of the selected
unit.

10. ADVANCED FUNCTIONS ELECTRONIC
BOARD E14
10.1. Heater pressure regulation from
pushbutton panel
With card E14 it is possible to regulate heater pres-
sure directly from the push-button panel without any
need whatsoever of a technician to intervene on the
internal electronics of the machine
This is possible thanks to an electronic pressure
transducer that detects heater pressure in real time.
To enter the regulation menu proceed as follows:
- Switch off the machine.
- Keeping push-button E of the first group pressed
(Fig. 3) switch on the machine.
- Push-buttons A and B will light up to indicate
1-bar default regulation.
In this menu, only push buttons A, B, C, D (Fig.
3-6b) of the first group are active with the following
functions:
A = Push button + (pressure increase with 0.1-bar
step).
B = Push button – (pressure decrease with 0.1-bar
step).
C = 1 bar (factory set at 1 bar).
D = ESC (regulation save and exit from menu).
To increase pressure
Press push button A, considering that each time it is
pressed, heater pressure increases by 0.1-bar step
up to a maximum 1.4 bars.
Pressure increases instantly (regulation visible by
means of heater pressure gauge).
To decrease pressure
Press B, considering that each time it is pressed
pressure decreases in real time by 0.1 bar step to a
maximum of 0.6 bars.
Opening the steam head, the new pressure regula-
tion can be assessed immediately by means of the
heater pressure gauge.
Push buttons A and B flash to indicate setting of
heater pressure as follows:
