Bypass Adjustment
The bypass valve adjusts the amount of water which
bypasses coffee grounds and dilutes the final brew
(see Figure 4). The factory setting is no bypass.
Bitter coffee results when the amount of ground
coffee is too small. Therefore, if your coffee is
brewing too strong, it is better to adjust the bypass
valve instead of reducing the amount of coffee.
