Ok so I got called out for a low temp walk in not keeping temp. I had 15 psi suction with like a 75-80* suction.. So the condensor model is not really legible anymore but this is the compressor
Now the Tev Is a GFE 1 1/2-ZP (r-12)
So off the Copeland specs it should be 502 for low temp right? THen whats up with this valve?
I have no idea what refrigerant is in this system or if it has been converted over in the past so I guess I need to decide what to convert to and start there..
Just wondering about that TEV and Compressor
