InstrUctIons for BasIc oPeratIon

1. S wing the heating unit to the rear. Raise the plastic support plate and lock in position by tightening the right-hand knob.
2. P osition the model in the center of the model support plate. For taller models, flip the model support plate over and fill cup with
supplied glass pellets. note: If utilizing two-sided heating function, do not place model on base until after heating first side of
plastic.
3. P lace sheet of plastic on the upper support plate and secure by placing the locking ring over plastic and rotating clockwise.
Swing the heater into position directly over the plastic.
4. P ress the on / off button to turn on timer. Press set button once to modify timer setting, then press adjust button repeatedly to
change first digit of display. Press set button to advance to next digit. Repeat until time is correct, then press set to confirm. A
beep will signal that the timer is set and ready for operation.
5. F lip the heating / vacuum power switch to turn on the heater and start the timer. Observe the plastic as it heats. Follow
directions for the Essix Plastic you are using. Watch for sag depth, if plastic instructions specify. Excessive sag will result in a
thin appliance. In extreme cases, the plastic may be ingested into the vacuum motor causing damage to the motor.
6. O nce the timer reaches zero, it will begin beeping. To start thermoforming, twist the handle on the right side counterclockwise
to allow the plastic plate to drop over the model. The vacuum will automatically start once the plastic is lowered. Allow the
machine to run for the required time to cool the plastic, then flip the heating / vacuum switch off to stop the vacuum. The
heater is automatically shut off once the vacuum begins.
7. U sing the heating unit handle, swing the heating element to the rear of the machine. caUtIon: the surface of the heating unit
will become hot with use and is a potential burn hazard. Contact handle only.
InstrUctIons for two-sIded HeatIng
1. T he machine is shipped with the rotating plate locked by a screw (Item 12, Figure 02). Prior to use of two-sided heating,
loosen this screw using the supplied 4mm Allen wrench. The screw does not need to be removed.
2. Follow steps 1-4 of the basic operation process, making sure not to place the model on the plate yet.
3. U sing the timer, enter the total time that will be required to heat both sides of the plastic according to the manufacturer's
directions, allowing some time for flipping the plastic. The sheets may be thermoformed at any time before the timer reaches
zero so it is better to have too much time than not enough.
4. Once the overall heating time has been entered, switch on the heater to begin the heating process.
5. O nce the first side has been heated for the required amount of time, use the handle to swing the heating element 90°
to the left.
6. U sing the handle, rotate the plastic support plate counter-clockwise by 180° until you feel a click, thus exposing the other
side of the plastic to the heater.
7. Using the handle, return the heating element into position over the plastic.
8. Heat the second side of the plastic for the required amount of time.
9. Repeat steps 5 through 7 with the exception of rotating the plastic clockwise to return it to the upright position.
10. I f specified, continue the final heating of the plastic until it is ready for thermoforming. Once the plastic is at the ideal forming
temperature, follow the steps of the basic forming process until the appliance is formed. caUtIon: Never lower the plastic
when the plate has been rotated in the counter-clockwise direction. Always return the plastic to the original upright position
before forming.

troUBLesHootIng

1. Insufficient detail: This is often caused by improper heating or vacuum time. If your adaptation does not show enough detail,
allow the material to heat longer prior to forming and/or increase vacuum time. Refer to the directions included in your Essix
Brand Plastics for proper heating times.
2. Material creasing or tearing: This is a result of excessive heat. Reduce the heating time. If forming several appliances in
succession, unit will retain heat and require less heating time than normal. Adjust accordingly.
3. Material sticking to the model: Spray the model with Trim-Rite
4. Material sticking to material plates: Allow material to cool longer. Essix Freeze Spray
this process.
5. Material stuck in the vacuum holes: This can occur if the material is overheated and pulled into and through the vacuum
holes. Allow materials to cool completely. Attempt to pull the material from the platform. If the material is not protruding through
the vacuum holes, gently pry the material off. Excessive overheating of the material may cause permanent damage to the
motor and require return for non-warranty repair.
6. Heater does not function: Ensure proper power cord attachment. Ensure the power switch has been pressed to power the
unit. If the heater still does not function, check the vacuum. If neither work, check the fuse located near the unit's power inlet.
A spare fuse is provided with the unit. (see below for fuse replacement instructions).
If the unit remains non-operational, please call DENTSPLY Raintree Essix at 1-800-883-8733 for further assistance.

cLeanIng and MaIntenance

1. A slightly damp cloth can be used as necessary to wipe down the unit. No other cleaning should be required.
2. C heck the power cord for wear or damage (ie. heat damage, fraying, etc.) at each use and examine the plug to ensure that the
connections are fully seated. Never allow the heater to be placed over the power cord for extended periods as this may cause
damage.
3. K eep the heating coil free from moisture and never touch with tools or metallic objects.
4. f use replacement: The power inlet on the back of the unit incorporates a fuse. The fuse is rated for proper operation under
normal conditions. If the fuse needs to be replaced, an extra fuse is included for your convenience. It is located in the fuse
holder. First, remove the cord assembly from the unit by unplugging from the electrical outlet and from the unit itself. Use a
® Release Agent prior to forming.
® Coolant may be utilized to expedite
