No I guess I am not sure if it has an expansion valve. I did a search on why my pressures would be reversed like that and all I found was a possible damaged expansion valve or compressor. It is all brand new stuff. If it is a fixed orifice then what I found suggested the compressor. I can't imagine how in the world the compressor could have been damaged?
If it's a TXV they can fail open but in that case the low side will be too high, there will be little to no superheat, and the high side will be too high. High side of course is affected by OD temp as well as load.
Are you certain when you took pressure readings that you had the manifold valves CLOSED?
