DESCALING

45
Clean the coffee beans container periodically;
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
ring 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, immerse
the suction pipe into warm water and let water
flow through it.
For a more accurate cleaning, remove the
cappuccinatore and open cover (29). Clean the
outside part with warm water and rinse it with
cleaned water.
Descaling
Warning: The descaling operations
mus be carried out when the machine
components are cold.
Descaling removes limescale from all surfaces
and holes, thus ensuring a perfect operation of
valves, heating controls and other important
parts.
Note:
due to the complexity of the coffee
machine hydraulic circuit, the following descaling
cycles (automatic and standard) do not allow the
descaling of all tubes.
In fact, easily accessible components
such as the central unit (22) and its
plastic connection are excluded.
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 machine
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:
"DESCALE "
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, page 86.
The machine has been adjusted on a 25
°
òH
value, which causes the warning light to switch
on after 150 l approx.
Should it be necessary, the water hardness value
may be exactly programmed, following the
instructions shown at page 88.
The following adjustments are possible:
Hardness 4:
high water hardness, over 29
°
òH
(14
°
dH), i.e. 80 l water approx.
Hardness 3:
medium water hardness, approx.
20-29
°
òH (7-14
°
dH), approx. 150 l water
passage.
Hardness 2:
soft water, approx. 12-20
°
òH
(4-7
°
dH) approx. 300 l water passage
Hardness 1:
very soft water, less than 10
°
òH
(3
°
dH), approx. 500 l water passage
In hard water regions, a filter should be used
both to improve the coffee quality or to protect
the machine, thus reducing the descaling
frequency.
Note:
for this purpose, use a descaling product
suitable for coffee machines.
Never use vinegar!
Descaling can be performed in two ways:
Automatic descaling
Select this mode in the programming menu (see
page 90).
By means of keys
, move the asterisk at
the end of the line on the menu item
Descaling
and confirm the selection with the
ENT
key.
The following message will be displayed:
"DESCALING "
Pour a discaling solution into the water tank
(according to the instructions on the product
package). Switch the machine on the programming
mode. Place a large container under the steam/
hot water spout and open slowly the steam knob.
The automatic descaling starts: Small amounts of
descaling solution are pumped into the circuit.
Then the pump stops to let the solution take effect.
During this phase, the following message is
displayed:
"MACHINE IS "
"DESCALING "
After approx. 45 minutes, when the procedure is
accomplished, the following message will be
displayed:
"DESCALING "
"FINISHED "
Close the steam knob. The pump stops.
Press
ENT
button. A display message reminds
you to rinse away any possible descaling residues
from the machine.
"RINSE MACHINE "
Remove water tank, rinse it accurately and fill it
with fresh water. Turn the steam knob slowly on
and let all the contents come out. The following
message will be displayed:
"RINSING "
"FINISHED "
Close the steam knob. Go back to programming
function by pressing the
ENT
key.
Note:
By pressing the
ESC
key (hot water key),
it is possible to quit descaling procedure.
