My thought is the acc is not only a device to ensure the pump never pumps liquid but also somewhat of a refridgerant reservoir/filter. I believe that the added length of line from the evap to the accumulator will only act as an increase in acc size. As long as the evap is flooded, as you say, and the compressor never sees liquid it should work. We'll see...

At the moment the evap and cond coils are connected, evacuated and charged to 100psi to check for leaks. They have been sitting on the deck here for a few days as I watch the pressure rise and fall due to temp changes. No leaks. The evap box is all finished.
I hope to get it all installed next week.
