Be sure to obtain a dual-stage regulator from the gas supplier for the CO2
tank that is to be installed according to local codes. Connect ¼" ID (6.35 mm)
flexible tubing to the regulator. Connect the other end of the tubing to the unit's
CO2 inlet (located on the back top panel). Insert tubing over hose barb and
fasten with an appropriate clamp to assure a proper connection. Adjust the
regulator for 5 psi when CO
2 is to be injected into chamber. For optimum results,
do not exceed or reduce this pressure.
