Adjusting Pressures
It is the pressure differential between keg/brite tank pressure and bottle pressure that determines the rate of filling,
amount of foam and retention of CO2 in your product. Therefore, adjusting either or both pressures can result in a
more favorable fill.
1. Each spout must have its bottle pressure set individually.
2. The pressures during filling are adjusted to obtain a quick rate of filling with limited foaming. Excessive foaming
will trigger the fill sensors and stop filling prematurely. The bottle will begin filling again as the foam settles, but
this significantly slows down the filling rate.
3. Typical maximum inlet pressures from a keg or brite tank are 30 psi and 15 psi, respectively.
4. Turning the Bottle Pressure Knob counterclockwise will start venting the pressure in the bottle and allow product
to flow into the bottle. The more the bottle vents, the quicker it will fill, but foam can start to develop. The Bottle
Pressure Knob can be adjusted to achieve an acceptable rate of fill as evidenced by the visual presence of limited
foaming.
5. The inlet pressures can also be adjusted in conjunction with bottle pressures to change the filling rate and foaming
characteristics.
