From what I have read on the PCI Chillers, the two most common problems with operation are fans going out and not having enough flow through the chiller. Seems the barb connectors for the plumbing slow the flow down a good bit.
If you have a problem with the connectors there is a thread or two here on RC where people fixed it using standard 1" pvc connectors with some extra teflon tape wrapped around the fittings. The threads on the chiller are not standard, I believe they are metric, but according to the folks who swapped out their fitings say the tape does the trick.
Yep, Mrs. Claus is good to me all year round actually. The wavebox was delivered this afternoon and I was given the option to hook it up tonight if I wanted. I passed on that one, decided I would wait till Xmas.
