of the coffee in the filter is correct.
• If the brewing pressure is lower than
the pump calibration pressure (9
bar factory setting), it means that
the coffee has been ground too
coarsely, that the coffee has not been
compacted correctly, or the amount of
coffee is insufficient.
• The machine is also equipped with
the BPPC (Brewing Pressure Profiling
Control) system and relative lever (34).
• The "BPPC" adjustment lever (34)
allows you to modify the pressure
exerted on the coffee in real time as it
is being dispensed.
• To modify the pressure profile during
brewing, move the adjustment lever
(34) to the right or left respectively
to increase or decrease the pressure
(Fig.5).
• This allows you to control the coffee
brewing process manually and to
obtain the best possible result with
every kind of coffee or blend.
If the adjustment lever (34) is
facing towards the right (as in Fig.
5), the coffee brewing pressure
will be the same as the pressure
exerted by the pump (8-9 bar),
seen on the relative pressure
gauge (5).
It is not recommended to close
the adjustment lever completely
as the gauge pressure would
indicate 0 bar and delivery would
stop.
5–3. DISPENSING HOT WATER
• Before dispensing hot water, make
sure that the service boiler is on
(Switch (31) in position "I") and under
pressure (Pressure gauge (4) indicates
1.1 –1.3 bar)
• Place a container under the nozzle (9).
• Turn the hot water knob (6)
anticlockwise to dispense hot water.
• When you have enough hot water, turn
the knob (6) clockwise to stop delivery.
We recommend that you dispense
a maximum of 200 ml of water.
To protect the heating element,
the machine
has a filling time-out of 25
seconds. If the filling time exceeds
25 seconds, both PID temperature
controllers (29 – 30) are disabled
until the service boiler has been
completely filled.
5–4. DISPENSING STEAM
• Before dispensing steam, make sure
that the service boiler is on (Switch
(31) in position "I") and under pressure
(Pressure gauge (4) indicates 1.1 –1.3
bar)
• Before heating any drinks, carefully
dispense a small amount of steam
from the steam nozzle (10) by turning
the knob (7) anticlockwise to eliminate
any condensation that may have
formed in the boiler.
• Place the liquid to be prepared in a
container, immerse the steam nozzle
(10) into the liquid and slowly turn
the steam knob (7) anticlockwise.
The amount of steam delivered is
proportional to how much you turn
the knob. The more you open it, the
greater will be the amount of steam
delivered.
• When the required amount has been
dispensed, turn the knob clockwise to
stop delivery. Remove the container
and clean the steam nozzle with a
damp cloth.
To froth milk for a cappuccino:
• Place some cold milk into a container.
• Place the container with milk under
steam nozzle (10) then immerse it a
