Check out this video that shows you the process of installing a heating cable set on the floor. First you lay out your strips of metal or plastic that the wires will attach to. After you have laid them out on the floor and secured them, you test the cable to make sure that it isn't damaged. You then start to run the cable around the track back and forth. The cable has markers on it to show you when you are half way. If you find that the half way mark comes up before or after you are half way done the area, space the cable out more or less accordingly.
