Prior to installation, make sure there is a circuit breaker installed with a distance between the contacts
that allows for complete disconnection when there is a category III overload and that provides
protection against current leakage equal to 30 mA. The circuit breaker must be installed on the power
supply in compliance with installation rules.
If the power supply is not working properly, the machine can cause transitory voltage drops.
The electrical safety of this machine is only ensured when it is correctly connected to an efficient earthing system in
compliance with the electrical safety laws in force. This fundamental safety requirement must be verified. If in doubt,
request that a qualified electrician inspect the system. The manufacturer cannot be held responsible for any damage
caused by the lack of an earthing system on the electrical supply.
Do not use adaptors, multiple plugs, and/or extension cords.
Check that the type of connection and voltage correspond with the information on the nameplate: see
illustrations chapter,
Figure 1
.

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 on the machine’s water inlet that the pH and chloride values comply with current law.
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 specific maintenance plan must be implemented
according to the hardness detected and machine usage.
WARNING
Only use the supplied parts for installation. If other parts are installed, they must be new (unused
pipes and gaskets for the water connection) and they must be able to come in contact with potable
water suitable for human consumption (according to local laws in force).
WATER CONNECTIONS
Place the machine on a flat 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 six bar, install a pressure reducer set at 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 draining tube must NOT bend as shown in
Illustrations chapter, Figure 4
