Hi, Anyone know where I might can fine an Owners Manual to download for a Fedders Air Conditioner Window Unit? Model: AST12F2JA Serial: JX 400706 2596 BTU: 12,500 AMPS: 12 WATTS: 1390 VOLTS: 115 Looks to be an old unit but still cools well. Face plate and filter is missing. I think I got controls figured out except for the black switch which flips from side to side between air damper control and on/off knob. Thanks, Donnie
