Had to deal with a pretty bad hack job today, and am looking for a bit of help cleaning up.
Walk-in meat cooler. 401a
2 bohn WKE100BC evaps with EBFFE-A-C txv (R-12)
Tecumseh Condensing unit
Now, here is where it goes bad.
Somewhere along the lines, someone decided to change out the original compressor with a Copeland CS33K6E-PFV-979.
Now, the compressor failed overnight and I replaced it, like-for-like today. THEN I find out that the compressor is a 404a pump on a 401a system.
I talked this over with the boss and we decided on this plan of action. Next time anyone has to touch the refrigeration system, we replace TXVs and change out to either 402a or 404a depending on the oil in the system.
Thought, suggestions, and input please.
