## Questions & Answers

**Q: What is the reason for needing a solenoid? How will the system run without one?**
A: The solenoid will control the co2 output. When turn off the solenoid, there will not be co2 out from the generator. If without the solenoid, the co2 will keep output.

**Q: How long do I have to wait before using the set up in my tank?**
A: You can use it as soon as the needle is in the green.

**Q: How can i replace the needle valve. Mine is broken alternating between full throttle or 0?**
A: This isn’t a replacement part for the co2 generator it’s valve for a co2 tank. I recommend contacting the manufacturer.

**Q: For a 4l co2 generator, should i put in 600-800 gram each of material a&b? also do i pour in 300ml water or more? i've read different opinions online.**
A: I use 600 ml for the material each and 800 ml of water I freeze the water in try"s that make long round ice cubes the cube are made to put in  water bottles
