The chiller unit seems to be emitting a somewhat annoying high pitched whine - way more annoying than it's usual noise.  Maybe someone wants to take a look at this?

DYM - it does the periodically because it doesn't like non DI water - just pressing a button (up or down arrow) on the front panel will disable it
