Brewing Pressure Profiling Control - La Pavoni LPSGEG03 Instrucciones De Uso

remove the filter holder (12) from the
group head (11) by moving it towards
the left, empty the coffee grounds and
repeat the steps described above.
Do not touch the group heads or
the steam and hot water nozzles
when the machine is in operation
and do not place your hands
under the group heads or pipes
during delivery in order to avoid
possible scalding.
When the machine is new, the
filter holder may not be aligned
(perpendicular to the machine) as
shown in Figure 5. However, this
does not prevent the machine
from working properly. After
being used for a short time, the
filter holder will gradually become
settled in the correct position.
G = Position of the closed filter
holder when the machine is new
H = Position of the closed filter
holder after the machine has
been in use for a short time.
• Coffee should be ground
just before it is used. Once
ground, coffee loses its flavour
very quickly. If the coffee is too
coarsely ground, the coffee will be
light coloured and weak without
froth and if the coffee is too finely
ground the espresso will be dark
and strong with little froth.
• Warm cups help maintain the
coffee at the right temperature.
We therefore recommended that
before using them, you place the
cups on the cup warmer shelf (3),
which will be warmed by the heat
given off from the boiler.
• The pump pressure can be read
on the respective pressure gauge
(5) during delivery.
• The correct pressure for making
coffee is 8/9 bar.
5–2. BREWING PRESSURE PROFILING
CONTROL
• The pressure gauge (33) mounted on
the group head, allows the brewing
pressure profile of the espresso to be
read.
• This allows the user to make sure that
the grinding, pressing and the amount
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 LPSGEG03 models are also
equipped with the BPPC (Brewing
Pressure Profiling Control) system and
relative lever (34).
• The "BPPC" adjustment lever (33)
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
exerted (Fig. 4).
• 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
