2.8 ADJUSTMENT OF
THE PRESSURE
The pressure of the machine must be set
while the coffee is brewing. While coffee is
delivered, check with the smartphone app
Victoria Arduino E1 that the value reaches
9 bar, the optimum value.
In the event that it would be necessary, use
the knob located below the machine to
make an appropriate adjustment.
Turning the knob clockwise raises the pres-
sure, turning it counter-clockwise decreas-
es the pressure.
NOTE
By factory the pump pressure is set to
reach 9 bar.
2.7 WATER INPUT PRESSURE
FOR DIRECT CONNECTION
VERSION
Check with the smartphone app Victoria
Arduino E1 that the water input pressure is
between 0 and 5 bar.
NOTE
If the pressure is more than 5 bar, insert
a pressure reducer upstream to ensure
a value between 0 and 5 bar.
