The cooling system failure at the H-2 electronics building (FRS 4271) was due to a defective flex joint in the line set from a outdoor unit compressor to the building. The flex joint has been replaced and the line set and compressor are being drawn down. There will be a small vacuum pump running near the outdoor units throughout the night. If there are no more leaks, the unit will be recharged with gas and back running tomorrow. The vacuum pump will run unattended, however, if there are any issues with the running of the pump, please do not hesitate to call me. 
The commissioners have been apprised of this also.
