I have a Carlyle compressor mn#o6ET265360 208/230 v 3phase on a jobsite that has two unloaders, one on each side bank, 6 cylinder. Iam not sure if it is a hot gas or suction cut-off type unloader. I am going back Mon. AM to determine if the unloaders funtion correctly or even adjusted properly. The facilities mech. has been messing with them by screwing them in and out.
I have basic understanding of how they work but would like to first determine which type we have and the proper way to set them up. Any information would be appreciated.
