According to Jonathan Aoki, the electricians will be servicing another MCC which will result in loss of cooling water for about 8 hours starting at 16:00
March 30. We shouldn't be running the evaporator or any condensers at that time. |

| It's the NON-ACTIVE water that will go off. The evaporator is on sity water, so it will be OK. |
