personnel.The following safety instructions should be followed at all times:
Check that the electrical specifications on the ratings plate match the specifications of
the power supply at the point of installation.
The coffee machine must be connected to an earthed socket that complies with the
regulations in force in the country of installation.
You should protect the electric line of the installation with a circuit breaker switch
appropriated for the power consumption of the machine, specified on its ratings plate.
A residual current circuit breaker must be installed in accordance with the
characteristics of the area of the installation.
Check the characteristics, power rating of the system and that the diameter of the
cables are suitable for the power used by the machine.
Do not connect the coffee machine to the power supply via extension boards, adapters
or shared sockets.

INSTALLATION AND START UP
Water connection
Pressure and temperature
Starting the machine
The Installation of the machine to a water mains connection must be done by a qualified 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 fitted 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 flexible 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 fitted with a pressure gauge that will display the boiler pressure, if the machine is fitted
with a display it will also indicate boiler temperature.
Relationship between boiler pressure and temperature
