INSTALLATION

Before carrying out the installation carefully read the safety
instructions at the beginning of this manual and particularly
about how to put THE MACHINE INTO ZERO ENERGY
STATUS.
1) Once the machine has been removed from the packag-
ing, position it on a horizontal surface and proceed with
the installation as illustrated in the following paragraphs.
Arrange the accessories as follows:
2) Insert the ring in its seat inside the filter holder.
3) Insert one of the two filters.
4) Caution: danger of pollution.
DANGER OF POLLUTION
Tank Model
5) Open the hatch and take out the reservoir. Especially
the first time, wash the reservoir with soap and water.
Fill the reservoir with water and make certain that the
outside of the reservoir is dry.
6) Return the reservoir to its housing and close the hatch.
7) Make certain that the water drain tank has been
inserted.
Direct attachment version
5) Open the door of the tank and remove the hose for
direct attachment.
6) Connect the hose to the water supply and open the tap
upstream of the machine if present.
7) Make certain that the water drain tank has been
inserted.
Make certain that the cup support grill is positioned
squarely and is level.
8) Check that the steam lever is closed.
9) Make certain that the line voltage corresponds to the
requirements indicated on the label.
10) The preliminary operations have been completed and
the machine is ready to be set up.

FILLING THE BOILER

NOTE: if the sequence indicated below does not take place,
see the chapter entitled "TROUBLESHOOTING".
After having completed the preliminary operations:
1) Press the On switch on the right side of the machine;
the keyboard lights up. The machine automatically
loads the water into the boiler (initial time approxi-
mately three minutes). When the water has reached
the correct level, the heating of the water starts sig-
nalled by the resistance warning light coming on.
NOTE: the machine has an electronic level valve so it
automatically feeds in water to the boiler as
needed to restore the level.
NOTE: the machine safety system shuts down the
machine after the pump has been running stead-
ily for approximately 1,5 minutes (this prevents
the pump from overheating). In this case, switch
off the machine using the main switch and switch
on again to complete the first filling.
Whilst functioning, the keyboard is backlit.
The resistance warning light comes on when it is
necessary to heat the water in the boiler and when the level
in the boiler is sufficient.
2) Wait until the heating light goes off, indicating that the
water has reached the desired temperature.
NOTE
if the water light goes on, it means that the water
reservoir is empty or nearly empty.
NOTE remember that to obtain a good drink it is best to
use the cup warming shelf to keep the cups warm.
3) After the water has been loaded press a dispensing
button until water pours out from the unit.
4) At this point the machine has been set up and is ready
to make coffee or produce steam.
NOTE: At the start of the day's activities and in any case,
if there are any pauses of more than 8 hours, then
it is necessary to change 100% of the water in the
circuits, using the relevant dispensers.
NOTE: In case of use where service is continuous, make
the above changes at least once a week.

WATER SPECIFICATIONS

Monitoring of water recipe to keep it within required levels and
maintenance of filtration system is the user's responsibility.
Failing to meet and maintain water at the following levels
will void the entire warranty:
• Total hardness 50-60 ppm (parts per million)
(5-6 french degrees (°F));
• Water line pressure between 2 - 4 bar and water to be cold;
• Min flow rate: 200 l/hr
• Filtration level below 1.0 micron
• TDS (Total Dissolved Solids) level between 50 - 250 ppm
• Alkalinity level between 10 - 150 ppm
• Chlorine level less than 0.50 mg/l
• Ph level between 6.5 and 8.5.
