I did the OSCAI install today. Here is a link to the pics, which are not explained:

Note: I shortened the piping quite a bit before the final install.

 

Did you angle it forward, or does it hang down? Nice pics, but now you have to explain each step.

 

I just let it hang down. It hangs all the way down to the plastic liner. I couldn't see how to angle it forward, because the piping didn't have that much curve to it (even though it was flexible). I may revisit this.

The quarters are tight in there once you slip in 3" hose in that area, not to mention the fan sitting right there waiting to gobble up the OSCAI.

 

As for explaining the pics....give me a break

 

You never know, there are idiots like me who need a little help!
