IAW

/ SAT/ UNSAT / SAT/ UNSAT / SAT/ UNSAT / SAT/ UNSAT / SAT/ UNSAT
1. Space Inspection
A. Main header isolation and distribution valves (bulkhead and station isolation valves)
- Visually inspect valves.
- Test operate each valve using local electric operator.
- Test operate each valve from MCS console (EOS or CCS).
- Test operate each valve remotely using second deck control panel.
- Test operate all thru-bulkhead reach rods manually.
Note: For this operation, the header can be drained or full, but full header will result in some dripping from the nozzles. / 5555/017 A-8
B. Nozzle Locations
- Verify proper number of nozzles per space (AMR1=84; AMR2=82; AMR3=93; MMR1=100; MMR2=97)
