Regulators
The pressure-building regulator may be adjusted without removal from the system. The following pro-
cedure describes the process:
1 Fill the container with liquid product.
2 Open the pressure-building valve and allow the container pressure to stabilize for about an hour.
Note the pressure.
3 Loosen the lock nut on the adjusting screw on the top of the regulator. Raise the set point by turn-
ing the adjusting screw clockwise; lower the set point by turning the screw counterclockwise. When
decreasing the setting, the pressure building valve must be closed and the container vented to a lower
pressure. Repeat step two and observe the change.
1 Leak test joints between the high pressure cylinder regulator and the dump valve. Joints must be
leak free before proceeding.
2 Close the on/off valve and the dump valve.
3 Open the high pressure cylinder valve.
4 Set the high pressure regulator above the desired set point for the pressure builder.
5 Slowly open the on/off valve and observe the downstream pressure gauge.
6 When the regulator under adjustment closes, the pressure-building. Set point is indicated on the
downstream pressure gauge.
7 Close the on/off valve and open the dump valve.
