Some Final Basics Instructions

Finally, some basic instructions on how to use your pressurized CO2 system now that you have everything hooked up.

1) Ensure that a nylon washer is between the CGA320 nipple and nut (A).

2) Screw the nut (A) onto the CO2 cylinder. Tighten with an appropriate sized wrench.

3) Unscrewing the bubble counter nut (I), thread the rubber O-ring through airline tubing, and then attach the tubing to the barb. Take this opportunity to fill the bubble counter with water (other options include mineral oil or glycerin; the choice is yours). Screw the bubble counter nut back into place.

4) Ensure that the regulator pressure adjustment knob (B) is turned counter clockwise until there is no resistance. This ensures that the low pressure gauge (E) is not destroyed when the CO2 cylinder is first opened.

5) Open the CO2 cylinder valve (C).

6) The high pressure gauge (D) should read ~800 – 1000 PSI, depending on the level the CO2 cylinder is filled, ambient temperature, etc.

7) Turn the metering valve adjustment knob (G) clockwise until you feel resistance (this will close the metering valve to restrict gas flow). Do not overturn, as we will now reopen the valve (counter clockwise) to allow gas to flow.

8) Plug in your solenoid (F).

9) Slowly turn the pressure adjustment knob (B) clockwise, until the desired working pressure is reached. In this image, the working pressure is set to ~5 PSI. Gas should begin to flow and you should see bubbles in the bubble counter.

10) Adjust your needle valve (G) so that the desired flow rate is achieved.
