Figure 7. Showing the set screw on the pump to change pump pressure.
Notes
Do not set the pump pressure with a blind filter in the filter holder. When a blind filter is
used water in the system is trapped between a one-way valve and the blind filter.
Therefore, the coffee boiler pressure will not drop when the set screw is turned counter-
clockwise.
When pump pressure exceeds approximately 12 Bar, the expansion valve will open.
Increasing the pump pressure further will not result in higher coffee boiler pressure.
Do not set the operational pressure above 9 Bar since this will reduce the life-span of
valves, etc. in your Speedster dramatically.
