This was not exactly the response I was expecting.
This is a copy and paste from my e-mail to Customer Service at Dometic about the model AC unit in the AS. They were very quick to respond:
"There is not an operations manual for the Air-Conditioner. If you can tell us which style thermostat you have, we can send an operations manual for the thermostat.
If you are in need of any Dometic refrigerator or air conditioner or A& E awning parts you can call us at 1-800-544-4881 or purchase from any dealer or Camping World location.
If we can be of any future service do not hesitate to contact us. Thank you for choosing Dometic product lines.

I've looked all over the Web site and for this model there does not appear to be much info (620515). I don't really need the operation instructions (after all it's only two knobs) but it would be nice to have a complete set of instructions.
