Forum » CO2 green NRG Exclusive Problem

My system is new. I have attached the pressure reducer to a new 74 gr cartridge firmly by hand. When I open the pressure reducer no gas escapes. When I turn the pressure reducer from open to closed I can hear brief puffs of escaping gas but then it stops immediately. No consistent gas is released. When I screwed the cartridge gas on the first time some gas escaped around the threads so I know the cartridge is pressurized. When I unscrew the cartridge slightly some gas escapes around the threads so I know it is still pressurized. Any advice?

As I unscrewed the valve somewhat some plastic was extruded from what I assume is a pressure relief hole. Now CO2 will flow from this hole when the valve is somewhat unscrewed from the cartridge.

Well, I got the pressure relieved and unscrewed the valve so I see what was going on. It looks like there were two "o-rings" in the valve, two clear disks with a hole in the center. One of them looks shredded. Was the unit supposed to ship with both rings inserted? I screwed the cartridge on with hand strength only and I'm not a strong guy. Any thoughts out there?

Where can I get a replacement "o-ring" for this unit?

Could I get an exploded diagram of this valve please?

Turns out instruction text was correct and Figure 1 is wrong. Here are the instructions: "Take the pressure reducer (N) and make sure that the regulation knob is closed (turn clockwise) -Fig. 1-", I thought when turning the valve counter clockwise as indicated in Fig 1 a spring controlled pin would be released such that CO2 would be blocked from escaping into the central well. Unfortunately it didn't and this time the CO2 escaped from a different pressure relief hole. You might say that clockwise is "righty tighty" is obviously closed but Fig 1, and the fact that a small plus sign to the left of the word Hydor and a minus to the left led to imagine minus meant closed and Fig 1 was correct and counterclockwise was the way to go. A further indication these instructions are screwed up is that next statement referencing the valve reads "Slowly turn clockwise the regulation knob on the pressure reducer checking that the CO2 reaches the bubbles counter, then proceed with the first regulation setting the desired amount of bubbles". Following the text instructions the valve is already in the completely clockwise position! Geese. Open/closed, plus/minus, clockwise/counterclockwise! I have a nice CO2 burn on my hand now.

that should read plus to the left and minus to the right

Dear Customer, we thank you for your contact. Thanks to your inquiry, we have verified the instruction's texts and there is an error in the English translation. The right text should be: "Take the pressure reducer (N) and make sure that the regulation knob is closed (turn anti-clockwise) -Fig. 1-, then turn the pressure reducer upside-down and make sure that the o-ring is in the correct position and there are no particles or dust inside the connection or on the top of the cartridge. (M). Screw on the CO2 cartridge slowly..." This is an error relative only to the english translation: in fact the translation in the other languages is right. We guarantee we are already correcting the text, and we apologize for this inconvenience. In reference to the indications of turning the reducer upside-down, this is only for inspection that the o-ring is correctly positioned and there are no particles.We should have probably added a sentence indicating to turn back in an upright position the pressure reducer before screwing on the cartridge. Thank you again for informing us, we will update the English translation as soon as possible.
