It is possible to adjust the flow rate up or down inside the SeltzaHub. This may
increase the instance of E4 error codes and is not detrimental to the machine.
1. Turn off SeltzaHub
2. Remove 2 screws in the back top of the SeltzaHub
3. Remove the top cover
4. Locate the flow regulator. Mark the current screw location with a marker
in case you want to go back to the factory setting of 15 mL/second.
5. Turn flow regulator screw counter clockwise for increased flow.
Turn clockwise for decreased flow.
