ok this one looked more simple but i plugged it in the outlet and open the 2 valves but nothing seems to come out. the pressure gauge doesn;t move at all. is there a special way to turn this on. i thought it was empty but its sure heavy as hell.
hope this helps! http://www.greenair.com/co2-generator.htm instructions: http://www.greenair.com/pdf/co2generator-inst-legal.pdf http://www.greenair.com/pdf/gas-conversion-inst-2002.pdf
