INSTALLATION AND START UP
Pressure and temperature
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.
Standard pressure and temperature Fig. 01
Relationship between boiler pressure and temperature
Water connection
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.

Important:
Only use the hoses supplied with the machine. Never reuse hoses.
Make sure that the drainage tube is not twisted and ensure that the entire tube is below the
level of the drain cup.
Starting the machine
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
