      1. Make marks on FFU switches that are not turned off in MCE, IFI, PRM, PR3, PR2, BS, SR2, SR3, SRM, OMC with "Pink Tape".
        (Operated FFU / Total FFU) list is below.
        130 FFUs will be turned off. This corresponds to 26kW heating power.
        26kW corresponds to about two water cooler cooling ability (2 x 14kW).

      2. 4 people stand by (MCE, IFI, PRM), (PR3, PR2, BS), (SR2, SR3), (SRM OMC) FFU switchs.
      3. Keep taking sensitivity of FPMI condition by an operator.
      4. Turn off almost FFUs at the same time by 4 people, except for pink one.
      5. Check the difference btw FFU operation and alnost-no operation.
