INSTRUCTIONS and CARE

General Care

• DXTR and Dex are diagnostic tools for testing life support equipment and should be treated accordingly. Avoid chemical exposure and harsh treatment or abuse.

• Before long storage flush with fresh water and allow to dry thoroughly before capping.

• Individuals with latex sensitivities should be aware that this product contains dry natural rubber.

• To avoid production of pathogens, replace after each season of constant use in a warm and wet or humid environment.

Before and after using DXTR

1. Ensure DXTR is clean before use then remove caps and plugs.

2. Test DXTR. Squeeze bulb to ensure it compresses and expands back to original shape.

3. Close and open ball valve to ensure it functions properly. *

4. Open the Free-Flow/Defogger Valve on the dive helmet.

5. Install DXTR. Screw the female oxygen fitting end onto the non-return valve on the dive helmet. Hand tight. **

6. Close the ball valve on DXTR.

7. Squeeze and release the bulb on DXTR. A bulb that remains compressed indicates that the non-return valve is working. **

8. Equalize pressure. Open ball valve to equalize pressure and expand bulb.

9. Remove DXTR. Unscrew the female oxygen fitting on DXTR from the non-return valve.

10. Stow properly. After use immediately replace caps and plugs between tests in ends of

DXTR and stow in a safe location.

* Each unit is tested prior to shipping to ensure that all parts function and that it achieves a seal.

** Some fittings on helmets are worn or scarred and, in order to improve seal, may require a “bump” with a small wrench (1/8 turn or less).

Before and after using Dex

1. Ensure Dex is clean before use then remove cap.

2. Test Dex. Squeeze the bulb to ensure it compresses and expands back to its original shape. *

3. Open the Free-Flow/Defogger Valve on the dive helmet.

4. Push the nozzle end of Dex into the non-return valve on the dive helmet.

5. Squeeze and release the rubber bulb on Dex. A bulb that remains compressed indicates that the non-return valve is working.

6. Pull Dex away the non-return valve to equalize pressure and expand the bulb.

7. After use immediately replace the cap between tests onto the end of Dex and stow in a safe location.
