4. Water Installation Rules
WATER REQUIREMENTS
Water used in coffee machines must be potable and suitable for human consumption (see laws and regulations in force).
Check that the water inlet on the machine has pH and chloride values that comply with the laws in effect.
If the values do not fall within the limits, an appropriate water-treatment device must be inserted (respecting the local laws and compatible with the
machine).
If the machine uses water with a hardness exceeding 8°F (4.5 °D), a specic maintenance plan must be implemented according to the hardness
detected and machine usage.
INSTRUCTIONS
Only use the supplied parts for installation. If other parts are installed, they must be new (unused tubes and gaskets for the
water connection) and they must be permitted for contact with potable water suitable for human consumption (according
to local laws in force).
WATER CONNECTIONS
Place the machine on a at surface and stabilize it by adjusting and securing the feet.
Hook up the water connections as shown in the Illustrations chapter, Figure 2, respecting the hygiene, water safety, and anti-pollution laws in the
country of installation.
Note: If the water pressure can rise above 87 psi (6 bar), install a pressure reducer set at 29÷43 psi (2÷3 bar). See Illustrations chapter Figure 3.
Water draining tube: place the end of the water draining tube in a drain with a siphon for inspection and cleaning.
IMPORTANT. The curves of the water-draining tube must NOT bend as shown in Illustrations chapter, Figure 4.
