OpERATING TEMpERATURE ADJUSTMENT FOR THE ELECTRIC HEATING SYSTEM
The electric heating system of the appliance is already set by the manufacturer to operate at a temperature
of
120 °C in the boiler, corresponding to 1 bar boiler pressure. Boiler pressure is viewed on the pressure
gauge (4) situated on the front panel of the appliance.
In order to increase or decrease the boiler pressure,
it is necessary to operate on the electric pressure
switch (Pict 21) which is inside the machine (on the
right side), as indicated here below:
• Turn the adjustment screw anti-clockwise to
increase boiler pressure.
• Turn the adjustment screw clockwise to decrease
it.
Boiler pressure (at operating temperature) is normally modified exclusively in order to adapt the machine
temperature to the particular type of coffee blend so as to obtain the best result in the cup.
ELECTRIC CUp WARMER (optional)
In the models equipped with the electric cup warmer, to activate it, move the main switch button (3) from
position
1 (standard operation of the machine) to position 2. To deactivate it, move it back to position 1.
