4.3 Water softener (optional)
The water softener for softening the mains water can be manual or automatic, depending on
customer’s request.
Before connecting the water softener to the coffee machine, the resins contained in it should be
washed off as described in the user’s manual supplied with the appliance.
Note:
The water softener is considered an essential device to guarantee a proper operation of the espresso coffee ma-
chine. A water softening system should be provided in order to guarantee the efficiency, performance and duration
of the components in the machine.

1) Use the pipe 32 (900 mm, provided with the machine) to connect the cut-off valve of the mains to the tap
for water inlet to the water softener (figure 1).
2) Connect pipe 36 (1600 mm, provided with the machine) to the tap of water softener with the tap of the
coffee machine water system (figura 2 – 3).
4.5 Installation of water system with motor pump (optional)

4.7 Electrical connection
Instructions for a proper electrical connection of the espresso coffee machine:
• Before connecting the unit to the electrical mains, make sure that the data on the data
plate corresponds to the electrical mains.
• The tag is located on the left side of the machine (and can be accessed by removing the
lower tray).
• The electrical system provided by the client must comply with current standards. The
power socket must be equipped with a working earth connection. LA SAN MARCO
SPA will not in any way be held liable if legal requirements are not met. An improper in-
stallation can cause injury or damage for which the manufacturer cannot be held liable.
• For the electrical connection, it is necessary to install an omnipolar main switch upstre-
am of the power supply; this switch should be rated according to the electrical cha-
racteristics (power and voltage) shown on the rating tag. The omnipolar switch must
disconnect the power supply with a contact gap of at least 3 mm.
• If it is necessary to use adapters, multiple plugs and extensions, only products meeting
applicable safety standards must be used.
• To avoid any overheating of the power cable, unwind it completely.
