LA VENEZIA-17 ESPRESSO MACHINE USER MANUAL
5
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 water hardness is higher than 8° F, it is advised to install a water softener and, possibly, a
non-return valve before it.
If the machine is fed with water with a hardness of over 8° F, a specific maintenance plan
must be implemented to ensure correct functioning of the machine.
The amount of chlorine in the water must not exceed 100 mg/l; otherwise, install the
appropriate devices.
To connect the machine to the drain net, 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.
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 has a
descending path.
The coffee machine should only be connected to the power supply by qualified 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 differential 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.
