Starting the machine
The Installation of the machine to a water mains connection must be done by a qualied person.
Rinse around 20 liters of water from the main water supply before connecting the machine to the water
connection.
Connect the inlet hose that is assembled in the machine to the main water supply, which should have
a 3/8” male connection tted with a shut-off valve, tighten it with a wrench.
Use safe drinking water with hardness between 5ºfH and 8ºfH (French hardness degrees). If the value
is below this limit, the presence of corrosion of hydraulic components is a possibility. If the value is
higher than this limit, the presence of lime in the boiler will increase. In both cases the operation of
the machine and coffee quality will be affected negatively.
If necessary, connect the machine to a water softener or remineraliser to reduce water hardness. Use
the exible hose that is included in the accessory box of the machine.
Connect one end of the corrugated tube to the drain cup in the machine, connect the other to the
main drainage tube at the installation area.
Boiler temperature and pressure are directly related (see Fig. 01).
Machine is tted with a pressure gauge that will display the boiler pressure, if the machine is tted
with a display it will also indicate boiler temperature.
Relationship between boiler pressure and temperature
Standard pressure and temperature
Open the external supply of water to the machine.
Turn on the main power switch.
Press a drink button at the control panel on each
group, wait until water comes out continuously from
each of them. This way the heat exchangers in the
machine will be correctly lled.
Open the steam tap to release the air trapped in the
boiler.
The red lamp indicates that the boiler is heating.
The lamp switches off when the machine reaches
operating temperature.
The machine is now ready to use.
