Programming Doses; Setting The Boiler Temperature - Pasquini LIVIA G4 DEPID Instruction Manual

5.7 Programming doses

SION) (Fig.05)
a = single dose
b = double dose
c = continuous/programming distribution
To programme each single dose, proceed as
follows: keep the programming key pressed down
for about 5 seconds the key "PASQUINI" (Fig. 05;
pos. c) until the LED light flashes.
Select the desired dose by pressing the
corresponding key (a-b) (LED turns on); press the
key again one the desired dose has been reached
(LED turns off): the dose has in this way been
programmed.
Notes:
- The LED lights on the keypad flash intermittently:
low water level in tank.
- The LED lights on the keypad flash rapidly: low
water level in boiler.
- The LED light of the selected button flashes:
coffee ground too finely.
N.B.
If no water comes out from the distribution unit (Fig.
01; pos. 5) even if the boiler is pressurised and the
tank is at a working level, some air bubbles may
have formed in the circuit that stop the pump from
working normally or the aspiration pipe may not
have been correctly inserted in the tank.
To restore working order if air bubbles have
formed, proceed as follows:
1) Turn the main switch off (Fig. 01; pos. 1) and
discharge steam from the tap (Fig.01; pos. 9).
Wait for the machine to cool down completely.

1) and press the distribution button (Fig. 04;
pos. a) until the water comes out of the unit;
press the button again (Fig. 04; pos. a) and
wait for the machine to become pressurised.

5.8 LIVIA G4 version with PID digital
temperature control
(Fig. 11)
The Espresso Machine LIVIA G4 with temperature
control is provided with a temperature digital
controller, settable from 176°F to 212°C. This
enables to change the boiler pressure from a
minimum of 0.5 bar to a maximum of 1.7 bar.
5.8.1 Activation of machine heating
Press the main switch (Fig. 01; pos.1) to switch
on the machine; the temperature control display
(Fig. 11; pos. A) shows OFF, that means that the
heating element in the boiler is inactive.
To enable boiler heating press the button (Fig.12;
pos. B). The boiler temperature is displayed.
A dot in the bottom right corner of the display
signals the activation of the resistance (Fig. 12;
pos. C).

5.8.2 Setting the boiler temperature

The adjustment of the temperature in the boiler
depends on many variables such as outside tem-
perature, humidity, quality of the coffee, etc. and
is set at the factory at the average temperature
of 194°F.
Pressing the button (Fig. 12; pos. A) the displays
shows PrG, pressing the button (Fig. 12; pos.
B) the factory default boiler temperature (90°C),
corresponding to the pressure of 1 bar, is shown.
Now it is possible to change the temperature
setting using the buttons (Fig. 12; pos A/B).
3 seconds after pressing the last button, the
temperature control stores any change and returns
to display the boiler temperature.

Never exceed the temperature of 212°F
in the boiler, since the safety valve may
trip due to the pressure increase.
