1. Soak model until saturated.

2. Paint the model with Lang's Liquid Foil, or any other alginate based tin foil substitute. Allow the Liquid Foil to set.

3. FOR DENTURE REPAIR: Place denture on model and apply Lang's Jet Acrylic liquid, add powder then liquid alternately, or as a slurry.

4. FOR RELINING A DENTURE: Using any of Lang's self curing reline acrylics (Flexacryl, Immediate, Tempo), reline the denture as per the product instructions. Have the patient blow the denture out of the mouth when it starts to generate heat. Immediately place the denture in the Aquapres.

5. FOR FABRICATING AN APPLIANCE ON A MODEL: Build up to the proper thickness by adding liquid, then powder to the model. Be sure to put the model in the Aquapres before the material gets hot. The appliance can be cured in sections if it cannot be fabricated completely before setting.

6. Rewet the entire surface with acrylic liquid before submerging in the tank.

7. Place the mold and denture (or appliance) in tank.

8. IMPORTANT: Fill the tank with room temperature water to OVERFLOWING.

9. Center the lid in position, causing water displacement.

10. Slide tank into clamp until it rests flush against the metal stop pins. This centers the tank.

11. Turn the hand screw until the gauge reads 30 p.s.i. Note: Greater pressure will not increase the density or improve the quality of the acrylic. 30 p.s.i. is sufficient for optimum results.

12. Allow at least 5 minutes for the acrylic to completely cure. Curing can be speeded by using warmer water. However, this is not recommended, as self-curing acrylics will work better when cured at room temperature.

13. Unscrew the hand screw and remove the tank from the clamp.

14. While pushing the release valve to break the vacuum, pull up on the gauge to remove the lid from the tank. (Note: It is normal for the pressure to drop slightly as the water cools due to the expansion and contraction process.)
