Turning the machine on and off
6.4.1 Machine start-up
Turn the machine on using the main switch of the
machine ( 6 ).
Before using the machine, wait for a short time
(about 10 min.) until the gauge ( 4 ) indicates the cor-
rect working pressure (1-1.2 bars)
The light ( 3 ) indicates the proper water level of the
boiler, slow flashes indicate the phase of water loading.
During the machine heating stage (approx. 20 minutes), the vacuum
regulator valve will release steam for several seconds until the valve
itself shuts off.

Renewing the water
In case of breaks longer than 1 week, it is necessary
to perform the changing of the 100% of the water con-
tained in the hydraulic circuits of the machine, by using
the appropriate dispensing points:
If the machine remains inactive for a time longer than 1 week, the
Maintenance Technician must renew 100% of the water contained
in the hydraulic circuit, as indicated above.
6.6
Coffee grinding and dosing
It is important to have a dosing-grinding device next
to the machine with which to grind the coffee to use
daily.
The grinding and the dosing of the coffee must be
done according to that indicated by the manufacturer
of the dosing-grinding device. The following points are
also to be kept in mind:
• to obtain a good espresso it is recommended not to
keep large stocks of coffee grains. Observe the expiry
date indicated by the producer;
• never grind large volumes of coffee, it is advisable to
have the quantity contained in the dosing device and
to use it if possible by the end of the day;
• If possible, never purchase already ground coffee,
as it deteriorates quickly. If necessary, buy it in small
vacuum-sealed packages.
6.7
Preparing the filter holder
• Fill the filter with a dose of ground coffee (circa 6-7
gr.) and press it with the press;
• hook the filter-holder to the unit without closing it too
tightly in order to avoid excessive wear of the gasket;
• for the same reason it is recommended to clean the
edge of the filter before attaching the filter holder to
the dispensing unit;
• follow the procedures specified by the manufacturer
of the grinder.
