Cardox Technical Manual CO2 5.00 Liquid CO2 is pumped into the properly prepared tube to make the activation work. 5.01 Only liquid can be used. This is accomplished by getting the CO2 from a cylinder that is equipped with a siphon tube or dip tube. 5.02 CO2 gas is heavier that air so the tube packing and filling room should have a vent located near the floor. 5.03 When CO2 changes state from liquid to gas it passes through a solid ordry ice state. This chills any surface it touches. When releasing CO2 from a tube the tube may get very cold. Gloves should be used. 2. INSTALLATION 360° PNEUMATIC...

Cardox Technical Manual FILL STAND PUMP HOOK-UP AND OPERATION Cardox tubes are “charged” by pumping liquid CO2 from a 50 lb. bottle into the fill head of the tube until the desired amount of CO2 is contained in the tube. The Cardox Fill Station makes this a quick and simple operation. Proper hook-up and operation of the fill station are as follows: 1. Connect the CO2 supply line from the inlet of the pump to the supply bottle. NOTE: A bottle with a siphon tube is preferred but if not available, invert the bottle to supply liquid to the discharge valve. Always use an approved bottle inverter....

|Cardox Technical Manual 1. 2. 3. 4. Center Tube in Vise Rotate the jaws of the Rotary Air Vise so that the Cardox Tube may be placed horizontally into the jaws. Center the tube with the Fill Head on the right. Open the manual bleed off valve on the tube fill head with a 1/4" hex wrench. Pull up on the vise rotation lock and rotate the vise 90° counter-clockwise until it locks in a vertical position so the fill head is at the top. Make sure the fill head discharge hole is pointed away from you. Remove the fill head with 1-1/2” socket and 3/4” air impact wrench. 7. 8. 9. Remove Heater Remove the...

Cardox Technical Manual Cardox Technical Manual 14. Inspect Tube End Threads & Seat Again, inspect the threads and seat area for pitting and wear. If acceptable, proceed; otherwise send tubes to Pneumat for repair. Place a new copper gasket in the tube making sure it is sitting flat down against the seat. 16. Install New Shear Disc Place a new shear disc in the tube, rounded edge down, so it is resting flat against the copper washer. 17. Inspect Discharge Head Inspect the cutting edge of the discharge head looking for a clean sharp corner. If the edge is not sharp send to Pneumat for repair....

|Cardox Technical Manual 1. Make certain the Cardox firing tube has been properly rebuilt before charging the tube. Check Safety Bleed-off Valve With a 1/4” hex wrench check to make sure the Safety Bleed Off Valve in the fill head is closed. Place the EMPTY rebuilt tube on the scale using the supplied plac-tic tube rest to keep the tube from rolling off the scale. Set Tare Weight to Zero Set the tare weight by pressing the tare button on the digital display. The readout should display a zero weight. Place Tube into Fill Stand Put the tube assembly into the fill manifold at the top of the Cardox...

Cardox Technical Manual Cardox Technical Manual 12. Weigh Filled Tube Place the filled tube back on the scale to check the weight of CO2 that was pumped into the tube. If the tube does not have a sufficient CO2 charge (see chart below) put it back into the fill station and repeat Steps 4 through 11. The air pressure to the pump may need to be increased to obtain a proper fill weight. Dip both ends of tube in a bucket of water at an angle to check for leaks. Hold under water for a few seconds and watch for bubbles rising up from the tube end. If tube is leaking clamp it into the vise and review...

Cardox Technical Manual 5. FIRING A CARDOX TUBE - BASICS Charged Cardox Tubes are safe to be transported and handled with reasonable care and safety. Once a Cardox tube is filled with the proper amount of CO2 it is ready for activation. A filled Cardox tube should always be respected. Dropping a tube will not cause it to activate, but it could break the copper washer seals on either end and cause the tube to leak Tube Placement Drill a 2-1/8” diameter hole into the effected material to a depth that will put the discharge ports of the Cardox Tube in a position 12” – 18” from a free face. Try to...

Cardox Technical Manual Activating Proper activation of a Cardox Tube should be done with an activating machine. Disconnect the short-circuit and insert and tighten the leads into the screw-down connectors on the activating machine. READ the instructions on the activating machine to become familiar with its operating procedures. Verify by sight and sound that everyone is clear. Then, hold down the charging button until the red indicator light comes on to signal that the activating machine is now charged and ready. Depress the firing button and the Cardox Tube will be initiated. Misfires CAUTION...
