During the layout for the power rectifier board we found an error in the schematic drawing in the Shark paperwork. This error, and the correction I have made below, has been confirmed with a genuine board and it also makes sense when you study the drawing. I don't know if other Hankin pin schematics also have this error but it would be worth checking yours or at least print this picture and keep it with the manual.
It isn't a big deal but you never know - when fault finding it helps if the drawing is actually 100% correct.
