38 By holding the central unit by its handle,
slide it back into its original position, making
sure it is correctly engaged. Then close the
service door. Insert the coffee grounds con-
tainer again.
When fitting the central unit,
do not press "PRESS" (this
may cause damage to the machine)!
Warning: if the central unit is not correctly
fitted, the display shows
BREW UNIT MISS
It is not possible to brew coffee. The machine
does not work.
Coffee grinder
Never fill the coffee grinder with
water: it may damage the machine!
Descaling
Warning: The descaling operations mus
be carried out when the machine
components are cold.
Descaling is necessary to remove 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,
according to the water hardness degree. A
more frequent descaling is recommended wher-
ever the water hardness degree is very high.
DESCALING
This machine is supplied with a particular
warning light
DESCALING
READY FOR USE
Descaling must be carried out at the latest when
this message is displayed. In spite of the mes-
sage, the machine does not stop working. To
switch off the display, press the steam key for
approx. 5 seconds until the message disap-
pears.
Furthermore, said display warning may be
adjusted according to the water hardness de-
gree. The machine has been adjusted at the
factory to 25º _H value, which causes the
display to switch on showing the message
<<descaling>> after approx 150 l.
The water hardness value may be changed, if
necessary, following the instructions shown on
page 27.
The following adjustments are possible:
Hardness 4: high water hardness, over 29º
H (14° dH), approx. 80 l water passage.
Hardness 3: medium water hardness, approx.
20º-29º H (7°-14° dH), approx. 150 l water
passage
Hardness 2: soft water, approx. 12º-20º H
(4°-7° dH), approx. 300 l water passage
Hardness 1: less than 10º H (3° dH),
approx. 500 l water passage
In case of hard water, a filter should be used
both to improve the coffee quality and to protect
the machine, thus reducing the descaling fre-
quency.
Note: for this purpose, use a descaling prod-
uct suitable for coffee machines. Never use
vinegar to clean the machine; it might
damage it.
There are two ways to carry out the descaling
of the machine:
Automatic descaling
Switch the machine onto the programming
mode (see page 32).

Move the asterisk at the end of the line to the
menu item <<descaling>>. To activate this
menu item press ENT.
The display shows:
8 DESCALING
Pour a descaling solution into the water tank
(according to the instructions on the package).
Place a large container under the steam/hot
water dispensing tube and open the steam/hot
water knob slowly. The automatic descaling
starts. Small quantities of descaling solution are
pumped into the circuit. Then the pump stops to
let the solution take effect.
The display shows:
MACHINE IS
DESCALING
This operation takes about 45 minutes. As soon
as descaling is completed, the display shows:
and the pump stops.
DESCALING
FINISHED
Close the hot water knob and press ENT. A
display message reminds you to rinse away
residue from the machine
RINSE MACHINE
Remove the water tank, rinse it and fill it with
water. Clean the machine using the hot water
knob and let the whole tank content flow out.
The display shows:
RINSING FINISHED
Close the hot water knob again and press ENT.
The machine is in the main menu of the program-
ming mode. Press ENT. The machine is now in
the normal mode. After heating, the machine is
ready to work.
Note
Descaling can be interrupted any time by press-
ing ESC. Before doing this, close the hot water
knob.
DISPOSAL
Standard descaling
Switch off the machine. Pour a descaling prod-
uct into the water tank (according to the instruc-
tions on the package). Place a large container
under the steam/hot water dispensing tube (7)
and open the steam/hot water knob (9) slowly,
turning it counterclockwise. Turn on the machine
by pressing the main switch and let the descaling
product flow out of the dispensing tube for
approx. 1 min.
Turn off the machine with the main switch and
let the solution take effect for approx. 5 minutes.
Repeat this procedure two or three times, to
allow all the descaling product in the water tank
to flow out of the dispensing tube.
As soon as decalcification has been carried
out, rinse the water tank (11) thoroughly and fill
it with water.
Switch on the machine again and let water
(approx. 2 l) flow out of the steam/hot water
dispensing tube in order to rinse away residue.
The coffee machine is now ready for operation.
Important
A periodic descaling avoids expensive repairs.
The machine warranty does not cover damages
occurring as a result of the non-observance of
descaling procedures, improper use and any
other instructions contained herein. Maintain
the manufacturer's adjustment if the water hard-
ness degree is not known.
Storage of the machine
Switch off and unplug the machine
if it will not be used for long periods
of time.
Keep the machine in a dry place, far
from the reach of children.
Should the machine not be used for a long
period, keep it from dust and dirty.
