Adjusting Pressures
It is the pressure differential between keg/brite tank pressure and can 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 can 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 can 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 Can Pressure Knob counterclockwise will start venting the pressure in the can and allow product to
flow into the can. The more the can vents, the quicker it will fill, but foam can start to develop. The Can 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 can pressures to change the filling rate and foaming
characteristics.
