INSTRUCTIONS FOR BASIC OPERATION
1. Swing the heating unit fully to the rear and turn on the heating element switch (Fig. 1). It will
require approximately three minutes to preheat. Preheating the unit before use is especially
important when using materials .040" or thinner. These materials heat very quickly and it is
best to have the heating element temperature stabilized prior to use.
2. Place the cast (stone, gypsum, etc.) inside the Vacuum Maximizer® on the vacuum plate (Fig.
2). The vacuum machine will accommodate 1 full arch Essix trimmed cast.
3. Raise the hinged frame. Open the hinged frame using the handle provided and place a sheet
of Essix® plastic within the frame (Fig. 3). Center it carefully.
4. Close the frame and secure with the frame latch (Fig. 4). Swing the heating unit into position
squarely over the material (Fig. 5).
CAUTION: Move heating unit only by the handle provided. Do not leave the machine unattended
while heating plastic.
5. The plastic heats quickly and will be useless if allowed to drop excessively. In extreme cases,
the plastic may be absorbed into the vacuum motor causing damage to the motor.
IMPORTANT INFORMATION:
you are using. Instructions will indicate heating times, sag depth and what to look for when
thermoforming with a specific type of Essix® Plastic.
6. Observe the plastic as it heats. Follow directions for the Essix® Plastic you are using. Watch for
sag depth if plastic specifies (Fig. 6).
7. Turn on vacuum, then firmly lower the plastic over model (Fig. 7).
8. Push plastic into the under cuts of model with the Essix Accentuator® tool (Fig. 8).
Immediately spray with Essix Freeze Spray® Coolant (Fig. 9). This is an essential step. Not

only does it cool the plastic, prohibiting further thinning, but it "shrinks" the material around
the cast, realizing a tighter fit. Let the vacuum run until the plastic encased model is cool.
Open the release handle and remove the thermoformed plastic from the vacuum machine.
10. To remove the cast from the adaptation, first cut away the flat surplus plastic. Trim as close to
the cast as possible to facilitate handling. Universal Shears are recommended.
11. For hard, thin plastics (.040 or less thickness) use the Essix® Lab Knife (or any grinding wheel
suitable for trimming excess acrylic) to cut through the heel of the cast enclosed in plastic.
Using the cast removing instrument, lift the plastic off of the model. For other plastics, a
wheel saw or Precision Heat Knife are recommended for other trimming techniques.
12. Final, detailed trimming with scissors and polishing brushes will produce a smooth,
professional, finished appliance.
