4) Verify filling of boilers.
The installation is now complete and the
espresso machine should be heating to the
operating temperatures.
Brewing after first installation
Once the first installation procedures are
finished, before proceeding with brewing
coffee, hot water and steam, please follow
these steps:
• Engage the portafilter by inserting it into
the group head and rotate the handle from
left to right. Once the portafilter is inserted
properly, you can move the paddle on the
left side to start the flow of water through
the portafilter. Brew water through the
group for at least two minutes.
• Being careful to avoid burns, turn on
each steam wand for at least one minute.
• Turn on the hot water valve for the time
necessary to allow at least 1 liter of
water to be brewed.
5) Waiting for the espresso machine to heat to
operating temperature.
During this time, the pointer of the
Integrated brew group pressure gauge may
reach as high as 12 bar. This may happen
anytime that the heating element is in the
“on” condition. If the pressure exceeds 12
bar then it will be necessary to adjust the
expansion valve in such a manner that the
pressure never exceeds 12 bar.
In normal operating conditions, the
Integrated brew group pressure gauge
can read anywhere from 0-12 bar. When
brewing, the pressure should be set to
approximately 9 bar.
The machine is ready to brew water when
the power indicator light (red) is ON.
When the machine is warming up the
power indicator light (red) is flashing.
NOTE: As the steam boiler reaches operating
temperature you may hear air and steam
escaping from the boiler. This is a normal sound.
As the water boils, air in the boiler is replaced by
steam and exits through the vacuum breaker. As
the boiler get closer to operating temperature
the vacuum breaker closes and the steam is
no longer able to escape. This process allows
the air in the steam boiler to escape and to be
replaced by water vapor.
