4. Machine Operation and Coffee Preparation
1) Starting the espresso machine
a) Filling the boilers with water
Once the installation procedures have been
completed, it is necessary to fill the boiler
tanks with water. Complete the following
procedure to properly fill the boiler tanks:
• Coffee boiler
The water flows inside the coffee boiler
directly, as soon as the water system and
water filter/softener taps (if present) are
opened. Since the inflow of water will
compress the air in the boiler it will be
necessary to remove or “bleed” the air
from the coffee boiler. All air must be
removed in order to completely “saturate”
the coffee boiler/group assemblies. To
remove the air from the boiler, “bleed the
groups”, it will be necessary to remove the
group cover from the top of the machine.
First remove the group tray from the top
of the machine exposing the cup tray.
Remove the screws securing the group
cover and then remove it. Once removed
the top of the groups will be exposed.
Loosen the bleed screws one at a time (see
fig.4) to allow air to escape until water
flows from below the screw head.
Tighten the screw to stop the water from
flowing. Over tightening can cause damage
to the sealing washer and the group cover.
Repeat this procedure for all groups. Once
all air is removed from the coffee boiler,
reinstall the group cover by following the
removal instructions in reverse.
• Steam boiler
Turn the main switch (item 1 in Fig. 1) to
position “1” or ON, the automatic steam
boiler level gauge will be switched on,
activating the auto-fill solenoid valve and
the motor pump. This will fill the steam
boiler to a predetermined level and will
shut off when full.
Note: It may happen that the air inside the
steam boiler builds up pressure (which
may be detected through the pressure
gauge - item 2, fig. 1) when the water is
allowed to flow in; this “false” pressure
must be eliminated by opening the steam
valves (item 8, Fig. 1).
b) Turning the espresso machine on
Once you have completed these
procedures, check the display. Press enter
to confirm that the preceding procedures
are complete.
The installation is now complete and the
espresso machine should be heating to the
operating temperatures.
