HDT / Nordic Air ECU, 9k BTU

I am looking at a Nordic Air 9k environmental control unit for sale locally. Does anybody have experience with these, or know where to find the repair TMs?

I have tried searching for awhile with no success. Here is the data plate from the unit, an info brochure from the manufacturer, and a general info TM.

You can call hdt they will email you the manual. They are simple units pretty much any hvac tech can figure it out.
