Downloaded the manual, reasonably straightforward, pretty much exactly as advertised.
 ;
very helpfull
circuit diagram and sparepart list available
;
Very good reproduction (copy) of original manual. Didn't have a parts list, but schematic was completely labeled with parts. Complete instructions on how to adjust mechanical functions of the 8-track deck. Well worth having and at a very reasonable cost.
;
It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

For AH-A249E/AU-A249E The room is not cooled at all or not cooled. The compressor does not operate.
Push the button "TEST RUN" on the indoor unit, and wait 3 minutes.
Using a tester, measure voltage at the terminals on the terminal board.
Is the voltage between terminal "N" and" 3 " of the terminal board in the outdoor unit the power supply voltage ? YES
NO
YES
Is the voltage between terminal "N" and " 0 " of RY4 in the outdoor unit the power supply voltage ? NO
Measure resistances of TH1 and TH2.
Replace the PWB ass'y with a new one.
Replace the relay RY4 in the outdoor unit with a new one. Are the resistances conformed Fig. 1 ? NO
YES
Replace the thermistor ass'y with a new one.
The control circuit is normal. The compressor may be defective. The running capacitor may be defective. Refrigerant may be leaked. The outdoor fan motor may be defective. The outdoor fan motor capacitor may be defective.
