5- START-UP
We assume the machine has been installed
correctly.
■ Turn the On/O󰀨 switch (1 - g._5.1) from
position “O” to position “I”.
The indicator (2 - g._5.1) lights up with a
xed white light.
■Open the steam knob (3 - g._5.2). to start
lling the boiler with water (the noise of the
pump must be heard).
When the boiler is correctly lled with water,
the pump stops (the noise stops).
■ Then close the steam knob.
g_5.1
g_5.2
The boiler heating begins.
Wait for the boiler pressure gauge (4 - g._5.3)
to indicate approximately 1 bar.
■ Open the steam knobs (3 - g._5.4) for 5
seconds to allow some steam to escape.
This operation is highly impor-
tant as it eliminates any vacuum
inside the boiler which may
cause milk to be sucked into the
boiler once steam dispensing
has begun. Close the steam knob
again.
■ Wait for the boiler pressure gauge (4-
g._5.3) to reach 1 bar again.

The maximum duration of a single
dispensing is 100 seconds. After
this time, dispensing stops auto-
matically even if the user has not
closed the lever.
Dispensing has priority over lling:
if dispensing is requested while the
machine is lling water, lling is tem-
porarily suspended and dispensing
begins regularly. It is possible to
dispense even when the machine
has not yet reached the rst level.

Maintenance operations must be
carried out when the machine is
o󰀨 and cold. Some particular op-
erations must be performed when
the machine is operating.
Do not clean the machine by using metal
or abrasive devices, such as steel wool,
metal brushes, needles, etc. or general
detergents (alcohol, solvents, etc.)
