Important
Before preparing the first coffee, please rinse the machine by extracting about 35 water
tank fillings from the brew group and the hot water wand. When the machine is switched
off, more hot water can be dispensed.
Important
If you use large quantities of hot water through a water valve, please wait for the filled
water to reach the desired temperature.
7.3 Adjustment of the brewing pressure
Important
The brewing pressure of the machine can be adjusted manually by opening the machine
and adjusting the screw on the rotary pump. This adjustment must be carried out by
expert specialists.
7.4 PID display function
The PID control allows you to program the boiler temperature inside the boiler, so you can modify the
extraction temperature of the coffee from the brew group.
We recommend a temperature setting on the PID of 120°C at about 1.2 bar, which corresponds to an
outlet temperature of about 91°C. If the temperature is set lower, there will not be enough pressure to
froth milk.
