ADJUSTMENTS
The machine that you have bought allows
for certain adjustments that will permit
you to use it to its full potential.
Gaggia Adapting System
Coffee is a natural product and its char-
acteristics may change according to its
origin, blend and roast. The Gaggia coff ee
machine is equipped with a self-adjusting
system that allows the use of all types of
coff ee beans available on the market (non
caramelized).
• The machine automatically adjusts
itself in order to optimise the extrac-
tion of the coffee, ensuring perfect
compression of the tablet to obtain a
creamy espresso coff ee that will release
all the aromas, regardless of the type of
coff ee used.
• The optimisation process is a learning
process that requires the brewing of a
certain number of coff ees to allow the
machine to adjust the compactness of
the ground coff ee.
• Attention should be given to special
blends, which require grinder adjust-
ments in order to optimise the extrac-
tion of the coff ee - (see section Coff ee
Grinder Adjustment).
Coff ee Grinder Adjustment
Warning! The grinder adjust-
ment knob, inside the coff ee
bean hopper, must be turned only
when the grinder is working. Do not
pour ground and/or instant coffee
into the coff ee bean hopper.
Do not insert any material
other than coff ee beans into
the hopper. The grinder contains
moving parts that may be dangerous.
Therefore, do not insert fi ngers and/
or other objects. Only grind setting
by means of the appropriate key is
permitted. Turn off the machine by
pressing the ON/OFF button and re-
move the plug from the socket before
carrying out any type of operation
inside the coff ee bean hopper, due
to reasons other than the adjustment
“INTENZA” water filter (op-
tional)
To improve the quality of the used water,
it is advisable to install the water fi lter.
Remove the water fi lter from its packag-
ing, immerse it vertically (with the open-
ing positioned upwards) in cold water
and delicately press the sides so as to let
the air bubbles out.
Remove the small white filter from the
tank and store it in a dry place sheltered
from dust.
Set the Intenza Aroma System as specifi ed
on the box.
A = Soft water
B = Medium water (standard)
C = Hard water
Insert the fi lter into the empty tank. Press
it until its limit stop.
Fill the tank with fresh drinking water and
reinsert it into the machine.
Dispense the water in the tank by using
the hot water function (see section "Hot
water dispensing”).
Fill the water tank again. The machine is
now ready to be used.
Note: If there is no Intenza
water fi lter, insert the previ-
ously-removed small white fi lter into
the water tank.
