Electrical installation
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!
OFFICE LINE
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.

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” 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.
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.
Important:
Only use the hoses supplied with the machine. Never reuse damaged hoses.
Ensure that the drainage tube is not twisted and that it is below the level of the drain cup.
Pressure and temperature
Boiler pressure is directly related to water temperature (g. 01).
Machines tted with a pressure gauge will display the boiler pressure, while machines is tted with
a digital display it will indicate water temperature.

Filling the water tank
DANGER!
Avoid spills inside the machine. If spills occur, turn the machine off and unplug the
power supply until the machine is completely dry to avoid RISK OF SHOCKS.
Note:
i
Always use fresh water with a pH water with a hardness rating between 5ºfH and 8ºfH (French
hardness degrees) or 20 to 32 ppm (parts per million as calcium) to ensure great tasting coffee
and to prevent limescaling.
Option 1:
Remove the top panel/cup warming tray.
Remove the water inlet tube and water softener unit, then
remove the water tank.
Fill the tank with clean, fresh drinking water (max. volume = 2.75L).
Replace the water tank in the machine, then replace the softener unit, with
the inlet side pointing down.
Replace the top panel/cup warming tray.
When the boiler is lled and heated, the machine is ready for use.
Note:
i
The machine has a microswitch located below the water tank to automatically stop the
machine’s pump when the tank is empty. Therefore, the water tank should only be removed and
relled when espresso is not being brewed.
Option 2:
Remove the top panel/cup warming tray.
Using a pitcher, carefully ll the tank with clean, fresh drinking water (max.
volume = 2.75L). Avoid spills inside the machine.
Replace the top panel/cup warming tray.
When the boiler is lled and heated, the machine is ready for use.

Important:
To prevent limescale build up in the
boiler and other components, a watersoftening system must be installed in-line
ahead of the machine.
Note:
i
For models which have both water tank
and water mains connection, the water tank
must be removed and stored and a 1-2 kg
water-proof, heat-resistant object (such as
a sealed, lled plastic bottle) must be put
in its place to ensure the pump-control
microswitch remains on. Failure to weigh
down the microswitch will prevent the
machine from lling the boiler.
Starting the machine
Fill the water tank or open the water mains supply valve.
Turn on the main power switch.
Press a drink button at the control panel or raise the group lever then wait until water comes out
continuously. This ensures that the heat exchanger in the machine is being correctly lled.

Coffee machine cleaning
Important:
To keep the machine looking and working like new, you should always follow the cleaning
and care instructions provided in this manual.
Always turn off the main power switch when cleaning the exterior of the machine.
All external surfaces should be cleaned with a damp, lint-free cloth that will not scratch the
machine.
Do not use aggressive cleaning detergents, solvents or degreasers. These can damage the
surfaces, and plastic and rubber parts, and leave unwanted residue.
Important:
Each day, or 8 hours after dispensing the last coffee, the following cleaning tasks should be
performed to maintain the quality and performance of the water system:
Portafilter: Brew one espresso with the filter empty (around one minute) to flush it out
(dispose of this water).
Steam Wand: Position the wand over the drip tray and open the steam lever for one minute
to flush the wand.
Hot Water Outlet: Place a container under the water outlet and dispense water for 10
seconds (dispose of this water).
Daily cleaning
Rinse the brewing group, shower plate, and portafilter with hot water for 15 seconds (page 27).
Clean the external surfaces of the machine with a damp cloth, paying special attention to the
stainless steel parts.
Clean the steam wand and the water tap. Be sure that the nozzles are not clogged or partially
blocked with milk or other residue. If it’s necessary to remove them for cleaning, be careful not to
deform or damage any of the components during removal.
Clean the dip tray and the stainless steel insert grid under running water with a brush.
Clean the drain cup by slowly pouring one liter of warm water into it to dissolve and remove the
coffee residue that accumulates inside the drain cup and hose.
Weekly cleaning
Clean the brewing group and portafilter with professional cleaning powder (see page 26).
Clean the water tank once per week with detergent and a bottle brush under running water to
prevent bacteria build-up. Rinse thoroughly and dry the outside before refilling and replacing it in
the machine.

Cleaning the gasket and shower plate
Cleaning the gasket
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 portafilter from properly sealing
to the group head. In extreme cases, such as leaving a used portafilter 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:
Place the cleaning membrane in the lter basket (without detergent).
Insert the portalter in the group head, but do not tighten fully (the portalter should be loose).
Press the Continuous Dispensing button for Control machines, or press the brew button
for Pulser machines. For Leva machines, raise the brewing lever for 15 seconds.
Make an opening-closing movement of the portalter in place without closing it. Water will now
ow around the portalter, owing through the closing surface and cleaning it.
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 portalter.
WARNING!
Do not fully tighten the portalter. If fully
tightened, high-pressure water may spray out
and cause scalding or serious injury.
Cleaning the shower plate
Remove the portalter from the group head.
Clean the shower plate and group gasket with a soft brush to remove any coffee residue.

Important:
Do not place wet cups directly on the
cup shelf. Allowing water to drip into
the machine can cause mechanical and
electrical damage.
Always remove and insert the portalters
gently. Never use excessive force to try to
close the portalter. If the portalter does
not turn and lock into place without excessive
force this usually indicates that there is too
much coffee in the lter basket.
