Insinkerator Excel 1 HP 7 YR SS Disposal, does this have the safety feature on it....that it won't turn on until the cover is on?

This disposer operates by a switch that turns it on and off.  It can be converted to a cover control by purchasing an adapter kit but the kit has to be installed by a ProCircle certified plumber.  Insinkerator makes a disposer with a cover control, the Evolution Cover Control Disposer which is available in our store. www.buyplumbing.net/index.html
