6. Are units chilled water Response: Yes. All CRAH units are chilled water.

8. Are there sufficient number of redundant units in order to take equipment down for retrofit ATS kits Response: Yes.
9. Is the secondary power from a backup generator or utility feed from independent source Response: Secondary power comes from alternate electrical distribution bus. Site is configured with two separate distributions paths supported by backup generator.

Manufacture is Eaton Cat #: CA:P4E250BT60CH01, 50kAIC Proposed alternate feeder for ATS and CRAH units in room 189 come from distribution panel manufacturer is Siemens Cat #: SB3 Rev. A, 65kAIC
