So this part
http://www.tunze.com/fileadmin/image...e/6080.400.jpg
slides into the groove (with the little loop to the back of the pump) I've circled:
Then you put the front "grill" onto the pump. Then this part here:
The loop on the swivel arm fits onto the circular piece out front there. Then the whole thing will fit onto a magnet at the back part of the mounting bracket above. You can use a sure grip magnet, it has the proper adaptor or get a tunze magnet. Sounds like Keith has something for ya
If you need more help, just get someone who has a tunze to hook you up with putting it all together. These are pretty specific parts so unless someone has a broken one that is unfixable you can get the parts from J&L. I accidentaly had the swivel arm go down a sink on me and I got a replacement for about $10 I think the bracket is about that much as well. So all in all you could easily get this thing going for less than $100. I bet someone would even build you an acrylic box for it if you wanted to fix it up like a wavebox
