Wow! This sounds almost exactly like our situation. We have a Liebert in our 
textile room which is part of a larger storage facility. The other units 
(not Liebert) are working fine. We have been struggling with the Liebert 
representatives and engineers to get them to make it work right for nearly 
three years - we want the temp to be about 62 degrees and the humidity to be 
around 45 percent, not an unreasonable request for such a unit. The unit has 
been so unreliable that I have yet to put one thread into storage there. The 
Liebert people have tried everything to make it look like it is our fault 
the system doesn't work e.g. the building isn't tight, the roof leaks, the 
system isn't designed right (they had to back off that claim when we pointed 
out it was their engineers that designed it). We are now waiting for summer 
to arrive once more to see if the unit will work, it has no problem 
maintaining the temp/humidity during the drier winter months but cannot seem 
to manage the dehumidifying task adequately.  With such an expensive system 
you don't want to resort to a $50 dehumidifier from Sears - which was also 
suggested at one point.
