8. For best results, set the temperature to 60°C. Use the -5 and +5 buttons to lower or increase the temperature.
WARNING: DO NOT SET THE TEMPERATURE ABOVE 60°C AS THE REACTION BETWEEN THE
CAUSTIC SODA AND THE WATER IS EXOTHERMIC, AND WILL CONTINUE TO ELEVATE THE
TEMPERATURE. ACTUAL TEMPERATURE SHOULD NEVER EXCEED 80°C.
9. Once the tank has reached 60°C, use the -5 and +5 buttons to set the timer for 180 minutes.
NOTE: The ultrasonic process will begin as soon as you have set the time.
10. After 180 minutes, remove your model from the tank using plastic tongs and run it under cold water for 1-2 minutes.
CAUTION: Continue wearing the recommended personal protection equipment when
handling the model until the process has been completed.
NOTE: All support material should have dissolved. Any remaining supports can be
crumbled or scraped away with a blunt knife or rinsed off in the sink.
11. Empty the caustic solution from the Ultrasonic Support Removal Tank.
NOTE: It is safe to pour it in the sink as caustic soda can be used as a drain cleaner.
12. Rinse the tank and refill it with 0.75 liters of water.
13. Using plastic tongs, place the model back into the tank.
14. Once all of the caustic soda has been cleaned from the area, you may remove your personal protection equipment.
15. Repeat the ultrasonic process with clean water for 30 minutes at 60°C to remove any caustic soda residue that may remain on the model.
16. Once the ultrasonic process has completed the second time, use plastic tongs to remove the model from the ultrasonic tank.
17. Rinse it under cold water for 1-to-2 minutes.
