• The heating of liquids by spraying steam.
• The milk foam production to create Cappuccino or Macchiatto.
The liquid to be heated should preferably be placed in a deep container.
The tip of the steam wand outlet must be immersed in the liquid, without touching the bottom of the
container.
The steam may also be used to sterilise and warm glasses.
After each use and absolutely after heating milk, always clean the stainless steel steam nozzle and
the outlet nozzles with a damp cloth, removing all traces present.
A rinsing of the steam lance inner holes is to be done by a short opening of the tap to release a jet of
steam.
 HOT WATER FUNCTION
A manual tap 'E' is provided for preparing tea, grog, etc.
Be careful, not to be burnt by the pressure water spray.
 FILTERS
The machine is equipped with two types of filters: 1 cup and 2 cups.
Each filter is operating with its own holder-filter to produce respectively 1 cup or 2 cups of coffee.
Filters need to be unclogged and clean, so they need to be cleaned almost once a day with hot
water, by being removed from the holder filters.
Take care to remove all residual traces of coffee and ensure proper cleanliness of perforations in the
bottom of the filter.
 FILTER-HOLDER
Never remove the filter-holder during operation of the group. The end of extraction is checkable with
coffee spouts: they no longer have to eject liquid.
Be careful to always keep the filter-holder engaged in the group, emptied of coffee cake, to keep
them warm.
In case of an extended stopping period, remove the filter-holder from the group, taking care to eject
the used grounds remain in the filter-holder.
Tighten the filter-holder until to be in contact with the seal, exceeding a little bit. The sealing is
guaranteed.
Do not unnecessarily try to crush the seal by tightening the filter at the maximum of your possibilities.
It may damage the seal or age it prematurely.
To empty the coffee filters used, turn the filter holder upside-down and lightly tap it on the edge of a
wooden box. Never strike it against metal or other hard objects.

 MANOMETER M1 : BOILER PRESSURE
The boiler pressure is adjusted in factory between 0,8 MPa (12 PSI) and 1 MPa (15 PSI). This value
varies slightly around its nominal temperature, due to the PID system which controls the heating and
limit the current consumption to its minimum.
NOTE: An over-heating thermostat will cut the heating, in case of an abnormal high temperature.
 MANOMETER M2 : PUMP PRESSURE
The pump pressure is adjusted at 9 MPa in the factory. Value which allows the best extraction of
coffee flavors. A bypass system evacuates over-pressure.
NOTE: Simultaneous operation of all the groups can impact a little bit the pressure level.
Visualization of the presence of water network is done by consulting the gauge
6.2. HOW TO USE THE PROGRAMMED DOSES

12. HOW TO MAKE THE PERFECT COFFEE
Obtaining a good cup of coffee is the result of certain conditions: the 5 golden rules of perfect
espresso:
MIX / GRINDER / MACHINE / HAND / and MAINTENANCE.
 The Mix:
o The type of coffee is very important. It can be distinguished 2 mains qualities:
 ARABICA:
It gives a fragant taste, sweet, chocolaty, slightly acid, with a pleasant bitterness. The coffee
color is hazelnut cream
 ROBUSTA:
It gives a less fragrant taste, rough, astringent and significantly more bitter. The caffeine
content is about twice. The coffee color is greyish brown.
o The roaster has a great importance on the quality of each coffee (choice of grain,
selection processes, roasting, packaging processes, ...).
 The Grinder:
The grinder and the grind adjustment are essential:
o The coffee grinder:
grinding capacity of the coffee beans must be commensurate with the needs of the
user. Indeed, excessive use causes overheating of the mill wheels and thus a rapid
realignment of the mill.
o The grind adjustment:
setting the mill to choose the fineness of the grind and the right dose required to
achieve optimum coffee. The dose should be adjusted to 7 grams for a cup; finesse
should allow a flow time of coffee in the cup about 20 - 25 seconds: this time ensures
the dissemination of flavors in the cup.
 The Machine:
It must be well adjusted and kept very clean !
o Pump Pressure limited to 9 MPa.
o Water temperature out of the shower must be between 86 °C and 92 ° C
o Correct programming doses.
o Daily cleaning performed every evening.
o Ensure that the water treatment is operating well.
o Follow the maintenance recommendations
