So, I was working on a walk in with a dual pressure control. It was low on charge. So, I fixed a leak and then went to verify it would pump down. But, it didn’t want to pump down in defrost. Compressor was running in a vacuum. So, I replaced the dual pressure control with two peanut switches. Anyway, when I pulled the flare off the suction line, I noticed there was a schrader in the access fitting. I don’t think those lines on the Johnson controls dual pressure controls have core depressors. Aren’t they just flares? submitted by /u/Silly-Wolverine6205 [link] [comments]
