[ALERT] October 8th Next Quarterly Maintenance Shutdown and ECM Project Drive Commissioning- Notice 1 of 3

[Physics facility information]

Quarterly PM (planned maintenance) on the PRB's four air handler units and six connected exhaust fans will be conducted by FOD on Wednesday, October 8, 2014.

Maintenance is scheduled to start at 7:00 AM and is planned to be completed by no later than 3:00 PM.

Because the lab side air handlers and connected exhaust fans will be shut down, fume hood operations should be suspended for the full maintenance period.

Occupants are reminded that although the building will remain open and accessible, air flows and other air-related building processes will be impacted throughout the day as maintenance is done.

In addition to normal PM activities, the ECM project will be transitioning the variable speed drives for Air Handler 1 and Air Handler 2 and the six Main Exhaust Fans to automatic control.

This transition will include tuning of the drive control loops and will require the units to be starting and stopping for short durations throughout the day as the loop tuning work is done.

Please take planned action to prepare for this event.

Key Summary Points:
- Air handler / Exhaust Fan shut down Wednesday, October 8th.
- No building closure or evacuation
- Suspend fume hood operations
- Building air flow and air-related processes will be interrupted throughout the day
- Expect frequent short duration stop/start conditions on AHU-1 and AHU-2 and exhaust fans for variable speed drive commissioning and control loop tuning.

For long range planning purposes, the 2014 quarterly maintenance dates are planned as follows:

Q1-2014 = January 9th Wednesday - Done
Q2-2014 = April 9th Wednesday - Done
Q3-2014 = July 9th Wednesday - Done
Q4-2014 = October 8th Wednesday - Announced

This message is Notice 1 of 3 of such alerts
