Co2ube Instructions
The Co2ube has been designed to work with ether a commercial Dura/Bulk tank, or a high pressure syphon tank.
Because the Co2ube needs liquid Carbon Dioxide to work, when using the Dura/Bulk tank you must connect the supply line to the “Liquid” outlet on the tank.
When using a High Pressure cylinder it must be a syphon style tank in order to pull the liquid co2 from the bottom of the container. For the most efficient production of Dry Ice we recommend the use of a commercial Dura tank
1. Remove from box.
2. Unscrew the “Tube”
and the “End Cap”
from the “Bracket Assembly”.
3. Mount the Bracket assembly to a solid surface using the four 1/4 inch holes provided.
The Bracket assembly should be mounted in a vertical position with the hose and valves above the Tube.
However the Co2ube will also work in a horizontal position.
4. Reassemble the Co2ube.
This is important! - Do not OVER TIGHTEN the end-cap or the tube!
A SNUG two finger tightening is all that’s needed!
The assembly is going to contract with the extreme cold, and if the pieces are too tight, they will bind. If this happens you will have a hard time getting the Dry ice out!
5. Connect the “Supply line” to your tank.
Always check to make sure the Teflon seal is inside the CGA fitting between the supply line and the tank.
6. Once everything is connected, make sure the control valve on the tube is closed.
7. Open the valve on your Co2 tank all the way.
Always use Safety Glasses and Gloves.
8. Turn the control valve ¼ turn until you hear the Co2 entering the tube.
On the high pressure tank, if you open the valve too much the safety valve will immediately start to pop.
If this happens back off the knob until it stops.
9. Let the Co2 fill the tube.
This will take about one minute. You will know when the tube is filled because the tube will start to “spit” and
start blowing gas out of one or two of its holes, or when the safety valve “pops”
10. Close the Valve.
11. WAIT FOR ALL NOISE TO STOP!
Once you have turned the control valve off, wait until there is no noise at all coming from the tube.
This only takes a couple of seconds.
Do not remove the tube if it is hissing because it is still under pressure.
If you want, you can open the valve one more time, then close it off again. This will produce a slightly denser piece of dry ice.
12. Unscrew the tube and remove the dry ice.
Now that the tube is cold it will produce dry ice faster and more efficiently.
When you are done making Dry Ice, it is recommend that both the valves on the co2ube AND your tank are closed.
