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
6.2 HOW TO USE THE PROGRAMMED DOSES

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 2
nd
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.
