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.

The PID temperature controller for the
