Electrical installation
The machine should only be connected to the power supply by qualified
personnel. The following safety instructions should be obeyed at all times:
Ensure that the electrical requirements stated on the TECHNICAL
SPECIFICATIONS (pages 7 - 8) match the specifications of the power
supply at the outlet.
Ensure that the domestic electrical supply where the machine is being
installed is rated for and able to provide the power required by the
machine. Insufficient power supply, wiring, grounding, or insulation can result
in overheating and possibility of fire.
The coffee machine must be connected to an earth grounded electrical
outlet that complies with the regulations in force in the country of
installation.
Ensure that a circuit breaker engineered for the power consumption of the
machine is installed to protect the domestic electrical supply, as specified on
the ratings plate located under the drip tray.
Do not connect the machine to the domestic power supply via extension
cords, plug adapters, or shared outlets.
The manufacturer will not be held liable for damage to persons, animals or
property resulting from incorrect installation of the coffee machine.
DANGER!
If the power cable or plug is damaged, it must be replaced by the manufacturer, distributor, or its
approved service technician in order to avoid RISK OF SERIOUS INJURY OR DEATH!
Connect the machine according to the specification on the ratings plate located under the drip tray.

INSTALLATION AND START UP
Main power switch
Water connection
Connecting the machine to the domestic water supply must be performed by a qualied person.
Purge at least 20 liters of water from the domestic water supply before connecting the machine to it to ush out
any debris that may be in the plumbing system that would otherwise accumulate inside the boilers.
The domestic plumbing system should be tted with a brass 3/8” NPT male pipe tting and an in-line
shut-off valve. Connect the 180cm water inlet hose included with the machine to the domestic water
supply and tighten the line ttings with a wrench to 15 ft. lbs. / 20N-m.
Only use safe drinking water with a hardness rating between 5ºfH and 8ºfH (French hardness
degrees) or 20 to 32 ppm (parts per million as calcium). If the hardness value is below this limit,
corrosion of hydraulic components is likely. If the value is higher, lime-scaling inside the boiler will
occur. In both cases, the proper function of the machine and quality and taste of the coffee will be
negatively affected.
If necessary, connect the machine to a water softener to reduce water hardness using the exible 55cm
hose included in the accessory box.
Connect one end of the corrugated drain tube to the drain cup in the machine, connect the other
end to the plumbing drainage system in the installation area.
Pressure and temperature
Starting the machine
Boiler pressure is directly controlled by water temperature (g. 01).
This machine is tted with a pressure gauge that displays the boiler pressure, if the machine is
equipped with a digital display it will also indicate water temperature.

CLEANING AND CARE
Cleaning the group gasket and shower plate
While making espresso, coffee grounds will naturally accumulate on the group’s sealing surface.
Allowing an excessive amount of grounds to build up can prevent the porta-filter from properly
sealing to the group head. In extreme cases, such as leaving a used porta-filter in the group head for
several days, water can even become blocked from passing through the shower plate.
To prevent these problems, perform the following cleaning procedures daily:
Install the blind basket into the porta-filter without cleaning powder.
Place the porta-filter loosely in the group head - do not close it fully.
Press the Continuous button .
Perform an opening-closing motion with the porta-filter in place without closing it fully. Water
will flow over and around the porta-filter, passing through the closing surface and washing out any
coffee residue. Be very careful to avoid splashes, as this water is very hot and can cause burns.
Press the Continuous button again to stop the water flow.
Remove coffee
residue with a
food-safe brush
Shower plate
WARNING!
Take special care to avoid scalding when
performing this cleaning operation, as the
hot water used to clean the gasket will spill
over the sides of the porta-lter.
WARNING!
Do not fully tighten the porta-lter. If fully
tightened, high-pressure water may spray
out and cause scalding or serious injury.
Cleaning the gasket
Cleaning the shower plate
Remove the porta-lter from the group head.
Clean the shower plate and group gasket with a soft brush to remove any coffee residue.

CLEANING AND CARE
Always remove and insert the porta-lters
gently. Never use excessive force to try to
close the porta-lter. If the porta-lter does
not turn and lock into place without excessive
force this usually indicates that there is too
much coffee in the lter basket.
Additional handling of the machine
Long-term storage
Machine disposal and recycling
Important:
Do not place wet cups directly on the cup
shelf. Allowing water to drip into the machine
can cause mechanical and electrical damage.
