Manual Brewing Pressure Adjustment; Setting The Temperature - La Pavoni LPSGEG03 Instrucciones De Uso

for approximately 2 seconds to allow
the circuit to perform a check. The
lamp (14) lights up to indicate that the
machine is powered.
• As soon as water starts to come out
of the group head (11) move the lever
(15) downwards to stop delivery.
• Wait until the coffee boiler reaches the
set temperature (92°) shown on the
PID temperature controller (29).
• Then turn on the service boiler by
placing the switch (31) to position "I".
The light (32) turns on to indicate that
the boiler is powered.
• The automatic water level device will
start filling the service boiler with
water until it reaches the pre-set
level; the level of water in the boiler
is monitored automatically and will
be topped up automatically to the
required level.
• During start-up: when the boiler
pressure gauge (4) indicates
approximately 0.5 bar, slowly open the
steam knob (7) to discharge any air
that may be contained in the service
boiler. Wait until steam starts to come
out of the steam nozzle (10) before
closing it.
• Wait for the service boiler to reach
the working pressure (1.1 – 1.3
bar), checking the boiler pressure
on the pressure gauge (4). The PID
temperature controller (29) is factory
set to 122°.
• Once the working pressure has been
reached, use the group head lever (15).
• Move the group head control lever (15)
fully downwards to stop delivery.
• The machine is now ready for use.
• The machine is fitted with
a safety device that checks
the amount of water in
the tank. The green light
(14) flashes to indicate
there is insufficient water
in the tank (2). If the water level
is too low, the device
automatically stops
all machine functions.
• As the tank is filled, the warning
light switches off and the machine
is ready to dispense coffee
again.
Coffee cannot be
dispensed and the boiler
heating element is not
powered when the
water tank light (14)
is flashing.
4–3. MANUAL BREWING PRESSURE
ADJUSTMENT
The brewing pressure can be adjusted
manually by turning the pump pressure
adjustment screw (F) (Fig. 3).
To check the pressure during delivery:
• Insert the filter holder full of properly
ground, dosed and pressed coffee into
the group head.
• Move the group head control lever
(15) and read the pressure on the
pump pressure gauge (4). The correct
pressure is 8/9 bar.
• If the pressure indicated on the
pressure gauge is not correct, turn the
pump pressure adjustment screw (F)
(Fig. 3) clockwise to increase the pump
pressure or anticlockwise to decrease
the pump pressure.
4–4. SETTING THE TEMPERATURE
The LPSGEG03 and LPSGEV03 models
are fitted with two PID temperature
controllers (29, 30).
The PID temperature controllers
regulate the temperature of both
boilers, which are programmable and
can be independently controlled.
This system makes it possible to brew
coffee at different temperatures.
