PSL Chillers Swapped for Backup

P. King, J. Bartlett, J. Oberling

Due to the high number of PSL chiller trips lately, this morning we swapped the in-service PSL chiller assembly (aka Gromit) for the the backup (aka Wallace).  Both crystal and diode chillers are currently up and running so that air can bleed from the system.  the laser is not on at this time, we will bring it back up this afternoon after enough time has passed for the air to bleed out.  Hopefully this solves the chiller trips we've been having recently.  Will continue to monitor.

Huge thanks to Jeff Bartlett for coming in on the first day of his vacation to help with the swap.
