External ltration device (Water mains supply)
1. Ensure that a water ltration device or system is installed in-line in the domestic water supply
ahead the machine to prevent contamination inside the machine’s hydraulic system. Contact a
service technician to do this task if you are not condent about performing the steps below.
2. Open the water tap and allow the lter to ll (if new/previously unused). Then the machine’s
steam boiler will begin to ll. Check carefully around the service area for leaks or drips. If leaks/
drips are detected turn o the tap immediately and check/tighten any leaking ttings.
Only use safe drinking water with a hardness rating between 5ºfH and 8ºfH (French hardness
degrees). 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 coee will be negatively aected.
If drinking water is not within the ratings shown above, a water lter must be installed inline ahead
of the espresso machine. Failure to install a water lter will result in voiding of the warranty and any
damage resulting from limescale buildup will be the responsibility of the owner.
Pro Tip:
Signicantly exceeding this operating range will result in excessive steam, high energy usage,
unexpected emergency machine shutdown due to safety valve activation and possibly
premature machine failure. Setting the temperature too low will resulting poor coee
extraction, slow group boiler heating, and low/no steam.

INSTALLATION AND START UP
1. Connect one end of the exible drain tube to
the drain cup outlet. (It is located under the
machine. Contact a service technician to do
this task you are unsure how to access this
area of the machine.)
2. Connect the other end of the drain tube to
the domestic plumbing drainage system in the
service area.
3. Remove the screw of the drain hole at the
bottom of the drip tray and replace/reinstall it
with the grill.
Flexible drain tube Drain cup
Pro Tip:
Ensure that the drainage tube is not twisted and that it is below the level of the drain cup to
prevent trapping water and other residue in the tube which could mold or produce bad smells.
Adjust the height of the machine with the feet if needed.
DANGER!
If supply cord is damaged, it must be replaced
by the manufacturer, its service agent or
similarly qualied persons in order to avoid a
hazard and SERIOUS INJURY OR DEATH!
Important:
The manufacturer will not be held
liable for damage to persons, animals
or property resulting from incorrect
installation of the coee machine.
1. The machine should only be connected to the power supply by qualied personnel. The
following safety instructions should be obeyed at all times.
2. Ensure that the electrical requirements stated on the TECHNICAL SPECIFICATIONS and on the ratings
plate located under the drip tray inside the machine match the specications of the power supply.
3. 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. Insucient power supply, wiring,
grounding, or insulation can result in overheating and possibility of re.
4. The coee machine must be connected to an earth grounded electrical outlet that complies
with the regulations in force in the country of installation.
WARNING!
Some models are equipped with boiler drainage.
Emptying the boiler must be performed by qualied
personnel.
