4. Installation
4.1 Warnings
The machine must be installed by qualified technical personnel authorized by La San
Marco S.p.A.
The grinder-dispenser is delivered to the customers in a suitable cardboard and styro-
foam package. The package contains the grinder-dispenser, its accessories, the user
manual and the compliance declaration. After having opened the package, check the
integrity of the grinder-dispenser and its components; in case of doubt, do not use the
appliance and contact the qualified personnel of the La San Marco S.p.A. service centres.
The package should be disposed of through the proper waste collection centres, in com-
pliance with the laws of the country where it is installed. Do not discard it in the environment. The packing
elements (carton, styrofoam, metal staples, etc.) can be hazardous. Keep away from children!
Place the grinder-dispenser on a perfectly horizontal surface that is sufficiently sturdy to support it, stable and dry.
4.2 Electrical connections
Instructions for a proper electrical connection of the grinder-dispenser:
• Before connecting the appliance to the power supply, make sure that the tag data of the grinder-dispenser
are the same as the network power supply; the rating tag is located under the grounds collecting tray.
• The connection must be made in accordance with the provisions of the country where the machine is in-
stalled.
• The electrical system prearranged by the customer must be in compliance with applicable standards. The
power socket must be provided with a suitable ground conductor. La San Marco S.p.A. declines any lia-
bility if the prescriptions of the law are not complied with. An improper installation can cause damage or
personal in-jury, for which the manufacturer cannot be considered liable.
• If it is necessary to use adapters, multiple sockets and extensions, use only products in compliance with
the safety standards in force.
• Unwind the power cable completely to avoid overheating it.
• The single-phase grinder-dispensers are provided with a three-conductor power cable and a plug for con-
nec-tion to the power socket.
• For the electrical connection of the three-phase models, install an omnipolar main switch upstream of the
power supply; the main switch must have the same electrical characteristics (power and voltage) as
shown on the machine rating tag. The main switch must be able to break the power supply with a con-
tact gap of at least 3 mm.
• The three-phase grinder-dispensers are equipped with a five-conductor power cable. The connection of
the three-phase models must be carried out as follows: (star connection for the models with 400V-3N~
power supply and delta connection for the models with 230V-3~ power supply).
• At the completion of the electrical connection, check that the motor turns in a clockwise direction (look-
ing at the appliance from above); if it turns counterclockwise, reverse two power phases.
• If the power is transformed from 400V-3N~ to 230V-3N~ or vice versa, use the adhesive labels provided
with the machine to update the data shown on the label glued at the end of the power cable.
