Yesterday I went to check on the chillers and found a bit of coolant on the CO2Y chiller air filter and on the bottom of the unit. The last time we saw this we had inconsistent supply temperatures, something we don't really see now but might explain our more frequent lock losses lately (alog 81362). We'll keep an eye on this and swap the chiller if necessary. It would be great if this could make it another 6 months and then we can send them in for service.

I replaced the air filter since it had a handful of dead bugs, coolant, and other junk on it. I used up our last filter so I'll have to order more.
