6 - COFFEE PREPARATION
In order to obtain an excellent espresso coffee, it is important to
use a top quality blended coffee, properly roasted and ground;
grinding is correct when the coffee delivery time is between 15-18
seconds for one serving and between 30-35 seconds for two
servings. The coffee should be grinded at the time of use. Once
ground, the coffee loses its flavour within a short time; if the grin-
ding is too coarse you will obtain light-coloured and weak coffee,
without froth; if the grinding is too fine you will obtain dark and
strong coffee, with little froth.
Once you have placed the filter into the filter-holder (
12
), fill the
filter with the amount of coffee required for 1 or 2 cups (7 gr. –
14 gr.), level it off, and press the coffee down with the presser,
manually clean the filter edge from any coffee residues and fit the
filter-holder into the brewing unit (
39
) moving it rightward tightly
in its place.
Place the cups under the spouts and start the brewing using the unit
control (
11
) or (
20
).
Once you have obtained the desired amount of coffee, stop the
delivery using the unit control (
11
) or (
20
) and leave the filter-
holder in its place.
To prepare additional cups of coffee, remove the filter-holder (
12
)
from the unit, moving it leftward, empty the coffee grounds into the
drawer provided and once again follow the previous steps.
Caution! We recommend not to touch the brewing units
or the steam and hot-water nozzles when the machine
is running, and pay attention not to place your hands
under the units or nozzles during the delivery, to avoid
possible scalds.
It is advisable to leave the filter-holders, with their own filters and
coffee grounds, fitted into the unit throughout your days’ work, so
that the filter-holder will always preserve an optimal temperature.
Caution! When the machine is new, the filter-holder may not be ali-
gned (perpendicular to the machine itself) as shown in the picture;
this however does not affect the proper use of the machine itself.
After a short period of use the filter-holder will be gradually settled
on the correct position.

7 - BREWING UNIT CONTROL
7.1 VRS and VRP MODELS
Machine equipped with semiautomatic, continuous delivery wor-
king with a micro switch.
Coffee delivery is obtained moving the small lever of the group
(
20
) placed on the control instrument board; bringing the small
lever downwards. The micro switch connected to it will start up the
pump for the delivery of water under pressure to the group.
The group through some inner devices, allows, before the pre-
infusion and after the infusion of the coffee in several ways.
Once the desired amount of coffee has been obtained, bring the
small lever (
20
) upwards, stop position, to stop delivery.
7.2 VRV MODEL
These models are equipped with automatic, continuous delivery
brewing units with solenoid valve and programmable coffee
dosing, microprocessor-aided sealed digital brewing control,
control board with 4 different coffee-doses selection positions and
a stop button.
7.3 - DIRECTIONS FOR COFFEE DOSE PROGRAMMING
Function of keys:
A. 1 normal cup of coffee
B. 1 “large” cup of coffee
C. 2 normal cups of coffee
D. 2 “large” cups of coffee
E. Brewing unit stop/continuous delivery
The (
E
) button is designed for continuous delivery and delivery
stop.
The machine therefore has a double function:
A
. By pressing the (
E
) button, the equipment is semi-automatic.
B
. By pressing the 4 selection buttons, the machine operates throu-
gh electronic dosing.
By holding the (
E
) pushing botton for few seconds, the machine will
enter in the programming phase, as signalled by the low frequency
flashing of the LED (
F
). Release the programming button (the LED
will continue to flash) and push the button of the unit related on
which you wish to program coffee dosing, at this stage delivery
will start; once the desired dose has been reached, press any
button of the unit to interrupt the delivery; the dose will be stored
in the memory and the machine will exit the programming phase
(the LED will stop flashing and will switch it off).
1. This operation should be repeated on the remaining selection
buttons for the various groups.
2. The same operation needs to be repeated if you wish to increa-
se or decrease the set dose.
COFFEE DELIVERY
To obtain the coffee delivery, push the selected button on the brew-
ing unit (
11
); the red LED (
F
) in the (
E
) button will switch on. The
coffee delivery will start and will be automatically interrupted once
the previous amount set has been reached. The stop of the delivery
will be signalled by the LED switched off.
The cancellation of the selection may be interrupted by pressing
any key on the brewing unit (
11
).
The (
E
) asterisk button, besides interrupting or aborting the delive-
ry, is also designed for continuous delivery, which means that the
dose is not previously set, but the unit will continue to deliver coffee
until the key is pressed again to interrupt the delivery from that unit.
LACK OF VOLUMETRIC COUNTER IMPULSES
On starting a volumetric control coffee cycle, the correct function
of the volumetric counter is checked by the reading of the number
of impulses sent by the same to the micro-controller.
Should no impulses by recorded for a period exceeding 5 seconds
the LED relative to the selected measure begins flashing (ie. the
led relative to key T4).
After one minute in which no impulses are recorded (volumetric
counter time out), the measure underway is automatically stopped.
NOTE: To avoid the automatic block of the machine, if
within 10 seconds the coffee delivery has not started
yet, press one of the selector buttons to cancel the com-
mand, replace the coffee contained in the filter basket
and repeat the delivery operation.
