Clean the coffee beans container periodi-
cally:
this operation should be accomplished
by a qualified technician!
Unplug the machine.
Empty the coffee container and unloose the two
fastening screws. Now, the container can be
removed and cleaned.
46
Carefully pull the adjustment lever upwards,
previously writing the set grinding degree.
47
Turn the adjustment ring counterclockwise,
until the blue marks coincide.
48
Now, it is possible to remove the grinding
ring from the machine, slightly pulling it upwards,
49
With the aid of a brush or a narrow vacuum
hose, clean both the gear box and the grind ring
support.
Make sure the position of the grind ring does not
shift.
To reassemble the coffee grinder, carry out the
reverse sequence, making sure the adjustment
ling has not been shifted during cleaning. If that is
the case, turn it until the blue mark coincide with
one of the three notches. Assemble the grind ring
support and make sure the blue marks coincide,
50
Turn the adjustment ring clockwise, to make
the red marks coincide.
51
Fit the adjustment lever on the ring, until it
coincides with the previously set grinding degree.
Cappuccinatore
52
To quickly clean the cappuccinatore, im-
merse the suction pipe into hot water and let
water flow through it.
For a more accurate cleaning, remove the
cappuccinatore and open cover (29). Clean the
outside part with hot water and rinse it with
cleaned water.
Descaling
Descaling removes limescale from all surfaces
and holes, thus ensuring a perfect operation of
valves, heating controls and other important
parts.
The machine must be descaled every 3-4
months, depending on the water hardness
degree. A more frequent descaling is
recommended wherever the water hardness
degree is very high.
To avoid dangerous delays to users, this ma-
chine is supplied with a special control counter,
reminding the user to perform this operation,
according to the water hardness degree. In this
case, the following message will be displayed:
When this message is displayed, the machine
does not stop: however, it is suggested to
descale quickly the machine. To cancel the
message, see programming menu indications,
point 1 4.
The machine has been adjusted on a 25°JH
value, which causes the warning light-to switch
on after 1 50 I approx.
Should it be necessary, the water hardness value
may be exactly programmed, following the
instructions shown at page 75.
The following adjustments are possible:
Hardness 4:
high water hardness, over 29°fF-i
(14°dH), i.e. 80 I water approx.
Hardness 3:
medium water hardness, approx.
20-29°JH (7-14°dH), approx. 150 I water
passage.
Hardness 2:
soft water, approx. 1 2-20°JH
(4-7°dH| approx. 300 I water passage
Hardness 1:
very soft water, less than 10°JF-1
(3°dh), approx. 500 I water passage
In hard water regions, a filter should be used
