I recently changed out a Copeland Discus compressor that was a burnout. I installed a suction line shell with an acid clean-up core and put a W-48 burnout block in the liquid line shell. Did an acid test today and there is no more acid. I'm going to remove the suction line core and leave the shell empty and replace the liquid line block. I have another W-48 block on my truck, so my question is, can I use it and leave it in the liquid line shell, or should I get a standard capacity D-48 block.
