UI Electrical Distribution will be shutting down some power to the Main Library this morning in order to accommodate installation of a new temporary dehumidification system.  The dehumidifiers that were being used the past two months are being replaced with a different system.  This shutdown will cause some air-handlers and elevators to be off, and judging from past experience this action will cut power to the equipment in the ITC area on second floor.  The shutdown is expected to last for a good portion of the morning.
