• Protect your body with appropriate
clothing and/or keep well away,
• Wear gloves providing protection against
heat,
• Keep exposed body parts, like your face,
well away.
2) Starting the espresso machine
a) Filling the boilers with water
Once the installation procedures have been
completed, it is necessary to ll the boiler
tanks with water. Complete the following
procedure to properly ll the boiler tanks:
• Coffee boiler
The water ows inside the coffee boiler
directly, as soon as the water system and
purier taps (if present) are opened.
Since the inow of water will compress
the air in the boiler, it will be necessary to
remove or “bleed” the air from the coffee
boilers. All air must be removed in order
to completely “saturate” the coffee boiler/
group assemblies.
To remove the air from the boiler, or “bleed
the groups”, it will be necessary to remove
the plastic keypad from the top of the
group.
Purge screw
Loosen the bleed screws one at a time
to allow air to escape until water ows
from below the screw head. Tighten the
screw to stop the water from owing. Over
tightening can cause damage to the sealing
washer and the group cover. Repeat this
procedure on all groups.

WARNING: hot water or pressurised steam
will inevitably ow out, so:
• Protect your body with appropriate
clothing and/or keep well away,
• Wear gloves providing protection against
heat,
• Keep exposed body parts, like your face,
well away.
• Steam boiler
Turn the main switch to position “1” or
ON, the automatic steam boiler level gauge
will be switched on, activating the auto-ll
solenoid valve and the motor pump. This
will ll the steam boiler to a predetermined
level and will shut off when full.
Note: Air existing in the boiler may generate
a certain pressure (which can be read on
the pressure gauge scale).
Once the pump stops, check the display.
The message “Coffee boiler lled?” should
be displayed. Press the encoder knob to
conrm that the previous procedures have
been completed.
The installation is now complete and the
espresso machine should be heating to
operating temperatures.
