AC Unit Shroud Removal Steps & Drain Hole Cleaning

A while back I found a thread where someone posted a diagram and step by step process for removing the AC Shroud and checking for proper draining and cleaning.

I even printed off the process....but now of course, I can't locate the printed page. I have done numerous searches but can't find it.

Anyone here have that, remember that or can point me in the direction of where it may be hiding?

Thanks!
