To calibrate the coffee dispensing pressure use the device code A 0128 ( Pic. A ).
The procedure is the following :
- replace the upper piston with the one equipped with pressure gauge (Pic. B)
- push a coffee dose key and rotate the pump adjusting screw to adjust the coffee dispensing pressure ( 8-9 Bar max.)
clockwise to increase it, and anti-clockwise to decrease it. The pressure will be shown on the gauge.
