1. MAKE CERTAIN THAT THE IRON CORE IS IN PLACE!

2. With the power switch in the 'OFF' position, plug the device in.

3. Turn the power switch on. You may hear a faint buzzing.

4. Take the copper ring, place it over the PVC pipe and let it go. It should hover about half way up the pipe.

5. Turn the power off and the copper ring will come to rest on the coil. Turn the power back on and the copper ring will leap off the device. Beware of low ceilings.
