Proceed with the initial start up operation of the machine after
the water and electrical connections have been completed.
Open the water mains valve (A) (fig. 2).
Switch on the protection disconnecting switch (D) (fig. 2).
Switch the machine’s main power switch (5) to the position
marked by: . The machine ON indicator will be ener-
gised (3).
NOTE: the machine will return to the OFF or ON
mode that existed before the mains supply was
disconnected when electric power is supplied to
the machine via the main power switch.
IMPORTANT
:
Do not press the hot water delivery button or switch
before the correct operating pressure has been
reached 1.1 atm, indicated by the boiler pressure
gauge (11).
7 - INITIAL START UP
OPERATION
The self-levelling mechanism will be activated until the
water reaches the normal level inside the boiler. (7).
The machine changes to ON mode after the correct levels
have been established; all the leds will be energised in this
mode and the display will show the current time, in hours
and minutes and the name (fig. 4.01).
Once loading has been completed switch the main power
switch (5) to the position marked: to operate in normal
power conditions or to the position marked: o operate
at maximum power, the heating resistors are energised in
this mode.
IMPORTANT
: if the heating resistors are activa-
ted immediately when the boiler is empty the
resistors only change to heated mode after the
water has been completely charged.
7.0.1 OFF MODE (Model “D” only)
The machine will be inactive but is energised when in the
OFF mode.
All the functions are disabled except the technical parameters
programmes.
The display will indicate the current time in hours and mi-
nutes. (fig. 4).
IMPORTANT
:
press key T5 with key T3 of unit 1 to change
from ON mode to OFF mode.
7.0.2 ON MODE (Model “D”)
Press key T3 (fig. 4.01) to change from OFF mode to ON
mode (Model “D” only).

7.0.3 ON MODE (Model “E”)
NOTE:
Model “E” is not designed with the OFF mode,
consequently the machine will be immediately in the ON
mode when the main power switch is switched to ON.
The self-levelling mechanism will be activated until the water
reaches the normal level inside the boiler. (7).
Once the correct levels have been reached the display will
show the information as indicated in fig. 4.02.
Wait until the machine has reached the operating pressure
1.1 – 1.3 atm. by checking the boiler pressure on the
pressure gauge (11).
If the machine does not stabilise at the values indicated then
the pressure switch will require calibration as specified in
paragraph 7.2.
Then check the pressure on the pump pressure gauge (10)
by operating one unit with the filter holder in position filled
with ground, dosed and pressed coffee to obtain the real
operating pressure of 8/9 atm.
If the pump pressure needs to be re-calibrated then this ope-
ration must be performed as specified in paragraph 7.3.
The machine is now ready to be used.
