Thread: Bohn Chiller

I've been working on a building that the building owner had his own maintenance guys repair for many years well that owner went bankrupt and a management company I work for took over. This chiller is from 1985 and it's a 90 ton chiller with 2 different circuits. The first circuit includes two 30 ton compressors and the 2nd circuit has one 30 compressor. Lets just say I've spent a lot of time repairing it.
My question is I have three condensers and they are individually controlled by head pressure controls and was wondering what I should set each of these for? It's an R-22 system. Right now they are set up for 1st: 195# 2nd: 215# and 3rd: 225#
