This morning both TCS chillers were powered down. 

   The X & Y reservoirs were siphoned dry. Then wiped out with towels. The pump, supply and return lines were blown out, and the lines drained. Dry break fittings were left in the supply and return lines, leaving them open to atmosphere, so any moisture left in the system and evaporate.

   Went into the LVEA and drained both TCS tables. Both lines on both tables were vacuumed to draw remaining moisture out of the lines and equipment on the table. Left dry break fittings in both lines on both tables, opening the plumbing to the atmosphere so any moisture remaining in the system can evaporate. The line ends with the dry breaks were covered with clean wipes to prevent critters form getting in the lines. Next time I can get LVEA access will remove the dry breaks and seal the table plumbing.   

   Not sure how successful the internal drying was done. The tote with the fittings for the clean vacuum, which is used to evacuate moisture from the site chillers, is missing from the cleaning area. Had to jury rig a hose fitting.
