OPERATING INSTRUCTIONS
•
after around 30 minutes, when the light comes on (chap. 12 - point
1), turn the steam knob half a turn clockwise (Fig.6) until it stops.
The machine must be rinsed so as to eliminate the residues of descaling
solution from inside the machine. Proceed as follows:
•
remove the water tank, rinse it and fill it with clean water.
•
reposition the tank.
•
empty the collection container (located under the milk frother) that is
full of liquid, and then replace it under the milk frother.
•
turn the steam knob half a turn anticlockwise (Fig. 5). Hot water will
come out of the milk frother and fill the container underneath.
•
when the tank is empty, the light goes off and the light comes
on (chap. 12 - point 1).
•
turn the steam knob all the way clockwise (Fig. 6) and fill the water
tank with clean water again.
•
the descaling program finishes after an hour and the machine is ready
to make coffee again.
NOTE: if the descaling procedure is stopped before completion, the
alarm (chap. 12 - point 5) is not deactivated and the procedure must
be started again from the beginning.
IMPORTANT: THE GUARANTEE IS NOT VALID IF THE ABOVE
DESCALING OPERATION IS NOT PERFORMED REGULARLY.
10.4 SETTING THE WATER HARDNESS
The light (chap. 12 - point 5) switches on after a preset period of operation,
set in the factory, considering the maximum quantity of lime scale that may be
contained in the mains water. If necessary, this period of operation can be exten-
ded, thus making the descaling operation less frequent, by programming the machi-
ne based on the actual lime content in the water used. Proceed as follows:
•
after having removed the "Total hardness test" strip (enclosed on page 2)
from its packaging, dip it fully in the water for a few seconds, then pull it out
and wait around 30 seconds (until it changes colour and a number of red
dots are formed);
•
check that the machine is off (all the indicator lights are off);
•
press the button (Fig. 14) and hold it for at least 5 seconds. The four
lights ,
,
and come on.
•
press the button (Fig.18) repeatedly until the number of lights that are
on coincides with the number of red squares on the test strip (for example,
if there are 3 red squares on the test strip, press the button until 3 indi-
cator lights come on together,
,
and ).
•
press the button (Fig. 14) to save the data. The coffee maker is now
programmed to provide the descaling warning when effectively necessary,
based on the actual hardness of the water..
