I'm tying in a condenser to an existing magic chef furnace and a-coil. The A-coil m# ya604pt. I can't find any documents on the coil and I need to know if it needs a txv or if there's some type of expansion device inside. There's a distributer inside and I can't tell if it's a fixed orfice. I took a picture of it so any help would be awesome. Thanks. Name:  ImageUploadedByTapatalk1367075900.769334.jpg
