Directions for Use

  1. Remove turntable plate and ring from the microwave oven and set them aside. Compare your microwave's drive impeller to the six drive impeller types pictured on page one. If your microwave's drive impeller is not described, please contact EMS Customer Service at 1 800-523-5874.
  2. To prevent the stirrer from slipping, ensure that the bottom surface of the microwave oven is clean and dry.
  3. Adjust the stirrer's suction cup feet so that they sit on the flat bottom of the microwave oven when the stirrer is centered. Secure suction cups.
  4. The impeller in the center of the microwave oven is the driving mechanism for the stirrer. Refer to Figure #1, on page one to determine the drive pin location.
  5. Place the center of the stirrer over the drive impeller.
  6. The stirrer is now ready for use. Place filled container with a Spinbar® Magnetic Stirring Bar on the silicone mats.
  7. Close the oven door.
  8. Set the microwave power, using this guide*:
    Time: 5 Minutes Power Setting: 100%
    Time: 10 Minutes Power Setting: 50%
  9. Start the microwave oven. The stirring bar will rotate. If the stirring bar is not rotating, stop the microwave and repeat steps 2 to 9 to remedy the problem.

*This guide uses 100% = 1000 watts. If the solution requires boiling for an extended period, lowe the microwave power after the solution starts to boil. Do not boil the solution for an extened period at the maximum power setting.
