Once installation has been completed, you can proceed
to hook up the filter holders (Fig. 4), together with their
filters, to the bottom of the groups by rotating them
from left to right; before operating the various switches
and thus powering up the heater elements, fill up the
boiler tanks with water, as follows:
1. COFFEE BOILER
The water flows inside the coffee boiler directly, as soon
as the water system and purifier taps are opened. Since
the inflowing water will compress the air in the boiler, it
will be necessary, in order to completely “saturate” the
boiler-groups assembly, to remove the group cover plate
(part 20 Fig. 3) and unscrew the small bolt (part 21) a lit-
tle way so as to allow air to escape until a few drops of
water leak out, at which point you should repeat such
operation for each group and then tighten the small
bolts again and reinstall the cover plate.
2) WATER BOILER
By turning the main switch (part 1) to position “1”, the
automatic level gauge will be switched on which, by
activating the solenoid valve and the motor pump (part
15), will fill the water boiler up to a predetermined level
selected by adjusting the probe inside the boiler itself.
N.B.
It may happen that the air inside the boiler builds up
pressure (which may be detected through the pressure
gauge - part 3, Fig 1 or 2) when the water is allowed to
flow in; this “false” pressure must be eliminated by open-
ing the vapourizing tap (part 10, Fig. 1 or 2).
Once you have completed these operations, turn the
main switch (part 1) to position “2” and wait for the boil-
ers to reach operating temperature and pressure (which
takes from 20 to 35 minutes, depending on the type of
machine), which will be subsequently maintained at a
constant value automatically.
During this time, it may happen that the pointer of the
lower scale on the pressure gauge (part 3, Fig. 1 or 2)
reach as high as 14-15 bar; this may occur any time that,
while activating the groups, the motor pump forces cold
water into the coffee boiler at a pressure of 8-9 bar and,
simultaneously, the thermostat regulating the tempera-
ture of the boiler itself switches on the heating elements
in order to bring the water contained in such boiler up
to operating temperature. However, in this case it is nec-
essary to adjust the 19A expansion valve (Fig. 3) in such
a way that the pressure may never exceed 11 bar.

Once you have ensured that the filter holders (Fig. 4) are
properly tightened, you should press the brewing but-
tons (part 5) 2 or 3 times and hold them pressed a few
seconds each time, in order to pre-heat the holders. You
may then remove the one that you want to make coffee
with (1 or 2 cups), together with its own filter, and pro-
ceed to place some ground coffee in the filter itself: 1
dose (approximately 6 g) for the small filter, 2 doses (2
coffees) for the larger filter. Press down on the ground
coffee with the supplied tamper and hook the filter hold-
er up again to the bottom of the group and then press
the switch (part 5) thus allowing coffee to be brewed;
when you have obtained the right amount of coffee,
press the switch again (part 5), at which point the
machine discharges the pressure built up in the filter
holder. The holder may then be removed to proceed
with making the next cup of coffee, if so desired.
CAUTION:
Do not remove the filter holder when its relative group is
brewing hot liquids. Such action may be cause for severe
burns.
