Remember, just like a wiring diagram, they are drawn in the off position. You have to imagine moving the mode dial to the different positions and then follow the flow of vacuum, in the different positions. Also the diagram shows five different spools; when in fact you’ll only see the one because they are all housed in the one vacuum switch. For example you turn the mode switch to defrost; all five of the spools will be in position 8. Dan.
