• Raise the brew lever and then turn the adjustment screw
labeled "B" Turning clockwise will increase the pressure,
counter clockwise to decrease the pressure. Recommend
setting to 9 bar using the lower pump gauge as reference.
After setting the pressure, lower the brew lever and then
•
tighten the locknut labeled "A"
Note: After adjusting the pump pressure then you may also need to adjust your grinder.
• Raise the brew lever and then wait a few seconds
for the pressure to rise. After the pressure has
risen, use a flat blade screwdriver to turn the
pump adjustment screw. Turning clockwise will increase the pressure, counter clockwise
to decrease the pressure.
• The recommended setting with the backflush disc is 9 bar. When you make espresso the
pressure may be slightly less due to less resistance.
• If the machine is able to put out 9 bars of pressure with the backflush disc, but when you
make espresso the pressure is less than 9 bars, this means the grind needs to be
adjusted finer which will create more resistance to raise the pressure. It is normal for the
grinder to drift a little over time and using different coffees or depending on the freshness
of the coffee may require a minor grind adjustment to stay in the preferred brew range.
• Tamping pressure can also affect brew pressure so be sure to tamp with the same 30lbs
of pressure each time. Tamping too lightly will cause the pressure to be low and the shot
will come out quicker. Tamping too hard and the pressure will be higher and the shot may
come out too slow or not at all.
