I have a Emerson Quiet Kool air conditioner. It is a through-the-wall unit. Although it looks like a very old model (still in brown color), it cools the room quite well. I want to clean its air filter. But I cannot figure out how to get access to the air filter. Unfortunately, the air conditioner comes with the old house and I don't have the manual. Moreover, I cannot find the company "Emerson Quiet Kool" in the web. Seem like it has disappeared, or it has been bought out by Fedder or something. Anyway, I cannot find the company or its product in the web nor in Fedder web site. I need your help.
Where can I find old manual of Emerson Quiet Kool air conditioner? What's happened to the company?
Thanks in advance for any info.
