according to local regulations.

English
4 EN
Handling
Staff responsible for moving the appliance must be aware of the risks in moving heavy loads.
Move the appliance carefully, using, where possible, the correct lifting equipment (fork lift, for
example).
If moving the appliance by hand, make sure:
- enough people are available for the task, depending on the appliance weight and how
dif¿cult it is to handle
- to always use the necessary safety equipment (shoes/gloves).
2.2 Installation Rules
• Before plugging in the appliance, make sure that the information on the nameplate (voltage, etc.)
matches that of the electrical and water systems.
• Check the condition of the power-supply cordif it is damaged it must be replaced.
• Completely unwind the power-supply cable.
• The coffee machine should sit on a Àat, stable surface at least 1 inch (20 mm) from walls and
from the counter. Keep in mind that the highest surface on the machine (the cup-warmer tray) sits
at a height of at least 47 inches (1.2 meters). Make sure there is a shelf nearby for accessories.
• 5oom temperature must range between 50°F and 89.°F (10° and 32°C).
• An electrical outlet, water connections, and a drain with siphon must be in the immediate vicinity.
• Do not install in rooms (kitchens) that are cleaned with jets of water.
• Do not obstruct openings or ventilation and heat vents.

English
5 EN
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 appliance can cause transitory voltage drops.
The electrical safety of this appliance is only ensured when it is correctly connected to an ef¿cient earthing system in
compliance with the electrical safety laws in force. This fundamental safety requirement must be veri¿ed. If in doubt,
request that a quali¿ed 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.
For machines with a single-phase connection: see illustrations chapter, Figure 2.
3. Electrical Installation Rules
4. Water Installation Rules
WATER REQUIREMENTS
Water used in coffee machines must be 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 speci¿c 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 permitted for contact with water
suitable for human consumption (according to local laws in force).
WATER CONNECTIONS
Place the appliance on a Àat surface and stabilize it by adjusting and securing the feet.
Hook up the water connections as shown in the Illustrations chapter, Figure 3, respecting the hygiene, water safety, and
anti-pollution laws in the country of installation.
Note: If the water pressure can rise above 87 psi (bar), install a pressure reducer set at 29·43 psi (2·3 bar). See
Illustrations chapter, Figure 4.
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 5.
ATTENTION: This equipment is to be installed with adequate backÀow protection to comply with the applicable
federal, state or local plumbing codes having jurisdiction.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated
in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

MANUAL POWERING
Press the luminous main switch.
The the keys light up and the following message will appear
on the display:
While waiting for the machine to be ready for use, insert
the ¿lter holders in the units.
The machine is ready to work when the display indicates
the working pressure:
If the water level in the boiler is lower than the minimum
limit, the boiler will be ¿lled to the right level. At the end of
this phase, the icon will appear in the lower left hand
corner of the display.
The preset working pressure must be reached before the
machine is ready for use.
If one of the keys is pressed during this phase, coffee
will be served at the temperature reached at that moment.

CAREFULLY PAY ATTENTION TO THE
SEQUENCEFORACTIVATINGTHESWITCHES
(1) AND (1A).
Press the luminous main switch (1) into position the
related indicator light switches on and the key also light up.
If the water level in the boiler is lower than the minimum
limit, the boiler will be ¿lled to the right level, indicated by
restored pressure in the manometer-pump.
During heating, if one of the coffee dispensing push buttons is pressed, the machine dispenses a coffee at the temperature
reached at the time.
Heating is completed when the boiler gauge indicator (19) remains stable in the Pgreen area.
The machine is now ready to dispense coffee, steam and hot water.
To make sure that the dispenser unit and the ¿lter holder (21) are at similar temperatures, press the coffee dispensing push
button (9) and let the machine dispense coffee for a few seconds. Then press again the push button (9) to stop dispensing.
ONLY AFTER the boiler ¿lling process has been
completed should you press the light switch that
activates the resistance (1A) into position the related
indicate light switches on and the heating phase begins.
Wait until the operating pressure (approx. 17psi - 1.2 bar)
appears on the manometer (19).
At this point, the machine is ready for use.
