Operation Tutorial Sequence:

1. Connect the external 8mm air hose and power cord to the rear panel, then turn on the red power switch.
2. Lift the heating unit handle and swing the heater aside to access the molding chamber.
3. Open the film clamp ring, place a 125mm circular thermoplastic sheet inside, and tighten the screws to secure it.
4. Place your dental model on the center base plate (ensure model height is ≤20mm).
5. Swing the heating unit back over the film clamp and lower it into the heating position.
6. Set the heating time, pressure time, and pressure level (1–9 bar) using the touchscreen interface.
7. Once heating is complete, quickly swing the heater away and flip the film clamp down over the model.
8. Lock the clamp handles tightly immediately to ensure a proper seal.
9. The machine will automatically apply positive pressure; wait for the pressure timer to count down.
10. Press the “air” button on the screen to release pressure, then unlock the handles and lift the clamp.
11. Remove the formed appliance, separate it from the frame, and trim the excess material.
