[Utility Outage] Scheduled HVAC Outage - 06/02/2014 09:30

[Carroll W. Jones]

The following HVAC Outage has been Confirmed:

Outage:      Switchover to Test Lab Basement Chillers
Proposed By: Carroll W. Jones
Start Time:  06/02/2014 09:30
End Time:    06/02/2014 10:00

Description/Impacts:
CUP Chiller maintenance is at the point where the CUP Chiller must be restarted.  The chilled water loops are being separated again and the CUP Chiller started.  The CUP Chiller will require another outage within the next week or so to address a refrigerant charge issue.

For additional information or clarification, please contact Carroll Jones at 757-876-1778.

________________________________________________________________________________
Central Chiller Plant loops will be re-combined this morning and all cooling will be provided by the Test Lab basement chillers. 

The primary impact will be a temperature fluctuation in the F-Wing Data Center during the transition process.  The TLA UHV Furnace should not be in use today, so no impact (if operational, the UHV Furnace could experience a chilled water flow drop during the transition process).

For additional information or clarification, please contact Carroll Jones at 757-876-1778 or Mike Sprouse at 757-846-1707.
