Sounds a little strange to me, Gene. More details with photos would certainly help.
What kind of AC do you have now? What is the pan made of?
The old Coleman that I replaced in http://www.airforums.com/forums/f427...ead-40795.html
had the drain tube attached to the metal bottom of the AC and could have been removed without the destruction shown in the photo when my helpers unceremoniously pitched it off the scaffolding while I was inside. Since it wasn't working, it was not an issue. It went to the scrap yard.
