6 HOW TO USE THE MACHINE
6.1 OPERATING ELEMENTS
STEAM FUNCTION
Two steams taps levers « V » are provided to allows:
• 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 pulse on the lever downwards to release a
jet of steam.
HOT WATER FUNCTION
Electric tap 'E' is provided for preparing tea, grog, etc.
Be careful, not to be burnt by the pressure water spray.
For that, the valve is coupled to a cold water mixing for adjusting the T ° water for teas and avoid spitting hot
water.
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 shutdown is controllable 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 to age 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.
Factory settings:
1. X-One = 1 MPa with setting range from 0.8 MPa to 1 MPa.
2. X-One TCi = 1.2 MPa with setting range from 1.0 MPa to 1.4 MPa .
NOTE: An over-heating thermostat cut the power on the general relay, in case of an abnormal high
temperature. The machine is not anymore supplied.
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

Put a detergent tablet (CONTI brand code: 466662) in the blind filter, and engage the filter-holder in the
group.
Keep pressing key n°5 (MENU), then press the key n°1 (1 espresso).
The cleaning process starts automatically, with a 1st step of 10 “ON and OFF” cycles. (The display shows
« cleaning in progress »). The purpose is to disolve the tablet, and release the cleaning agent on the coffee
group circuit and on the coffee valve.
Then this step stops for a 2nd step. (The display shows “Wait”). The machine waits for 1 minute in order to
make the product acting.
Release the filte- holder from the group and rinse it under water.
Then, the 3rd step, is a rinsing during 20 seconds. (The display shows “rinsing”).
When the cleaning cycle is finished, the message disappears, and the group available again.
Repeat this operating mode on each group, and each time the message « cleanning Grp i SVP » appears
on the display.
The cleaning cycle can be interrupted, pushing any key of the concerned group. But, you will lost the
following steps, and will compromise the cleaning efficiency.
It is possible to perform an automatic washing cycle for each group independently
7.6 ECONOMIC MODE :
The evening or before a long period of inactivity, the economic mode allows to keep the machine in standby
The display shows "ECO”.
Then the boiler is maintained at a temperature of 60 ° C:
• which saves energy during the temperature drop
• and also during the standby period because the set-point temperature is low.
The output of "ECO" mode allows the machine to come back quickly to its operating parameters without
spending lot of energy.

PID adjustment range
The PID is a system for adapting the heating power in the coffee boiler.
The goal is to have a better stability of the T ° in the coffee boiler
Principle of operation:
Every 2 seconds, electronics evaluates the power to provide to the heater. This calculation is performed in a
working range of 5 ° C around the setting temperature (range = 5 ° C). Beyond that, the machine is full
power.
This calculated power is depending on the measured temperature weighted by 3 coefficients:
•
Where is the temperature: Kp
•
At what speed is changing the temperature: Kd
•
How has evolved the temperature since the beginning: Ki
This gives a percentage rise of full power given to the heater. And It’ shown by the blinking leds on the solid
state relays.
It is recommended to keep the default settings.
•
PID system is a compromise between SPEED and PRECISION.
•
The aim is to limit overruns while maintaining accuracy, speed and robustness.
Filling up Time out adjustment:
It allows to allocate to the machine a maximum permissible time for filling the boiler.
Beyond this time, machine stops and an alarm message is displayed.
The values are in seconds.
The setting is made with + and – key.
To exit, press MENU, or wait 30 seconds.
Water softener:
This menu concern the water treatment parameters. We define the alarm threshold before changing the filter
(0 to 9999 litres).

• The water passes through the coffee flowmeters.
• The water enters the steam boiler
The setting is made with + and – key. (Hold the key for 5 seconds scroll faster)
To exit, press MENU, or wait 30 seconds.
When the water volume consumed is reached, the display shows:
To reset the counter, when the filter has been changed: see chapter “reset counters”

15 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

The Hand:
Skill of the operator: He must of course control the above three factors, but also:
He know how to maintain coffee.
o For exemple, a milling do not remain in the open air.
o He know that coffee bean loses 1% of its flavor by day ground coffee, it loses 45% day.
o Therefore he avoid grinding too much coffee at once, or keep in drawers.
The filter-holder need to be warm, so it must be maintained on the group.
The cups need to be warm, about 40 ° C. They are therefore placed on the cup warmer.
He damp correctly the coffee in the filter-holder.
He ensure proper regularity milling for constant quality coffees.
The Maintenance
This is the necessary condition for the success of a good coffee:
At the end of each daily period of activity, it is strongly recommended to perform a cleaning operation on each
group coffee.
Double impact:
o Improve coffee quality by eliminating oxidized fats
o Ensure the proper operation of the coffee group.
