Anybody have any information binders they would like to share via email? Fairly new to liebert systems and just want to become more familiarized with CRAC units.

Can't find your address. If you search for liebert system 3 manual, liebert ds manual, liebert icom manual, liebert minimate manual, and liebert challenger manual on Yahoo, they will come up in pdf form for downloading. Those will cover 90% of the lieberts out there, and give just about all the info you should need if you read from cover to cover.

Must be a regional thing. Here they are CRAC units.

In all fairness he was responding to the OP.
And he mentions a basic point that gets us " old dogs " at times " cooling and humidifying ". A paradox for sure and when you first see this it throws you away from air conditioning fundamentals that you learned in school.
Computer room air conditioning ( CRAC ) is often a hit or miss , the typical server room seems to have 10 times the capacity that it really needs to. This makes it difficult to correctly charge these systems as well. With the receivers and head pressure control options on these machines the sight glass is really the best method of charging or determining correct charge ( and I hate sight glasses on air conditioning systems ).
Cooling , humidifying , de - humidifying are sequences that you need to understand when dealing with these things. I would think that Liebert ( Emerson ) has a lot of information available online , if not I'm sure that SATS ( Stulz ATS ) does.

Just did my first 2 liebert startups Friday. Two challenger series units with the ICOM controller. They seem to be really nice units. The factory startup sheets took awhile to get done mostly because I was unfamiliar with the equipment, but it didn't go too bad. I actually enjoy working on unfamiliar equipment. It made for an interesting day.
