Jason, Jeff B., Yesterday we installed the new PSL chiller manifold. After fixing several small fitting leaks this morning the PSL chiller is back up and running. The flows and pressures all look good. In order to fit the manifold under the table, I need to change the manifold supply and return fittings from 3/4" straight FNPT to 3/4" barb to, 3/4" elbow (90)FNPT to 3/4" barb. Finding this fitting that is safe for use in a DI water system is proving to be a bit of a challenge. I have several queries out right now.
