TM 5-4220-231-14&P 1-9   Equipment    Data.   Table    1-2  summarizes the   functional   characteristics of  SDASS. Figure   1-2  demonstrates the functional block diagrams for each configuration of   SDASS, Figure 1-3    demonstrates the Diver Operations Functional Flow, and Figure 1-4   shows the Recompression Chamber Operation Functional Flow. Tables 1-3   and 1-4    are    the keys to   these diagrams. Table 1-2. SDASS Functional Characteristics. FUNCTIONAL AREA CHARACTERISTIC AIR STORAGE -  Volume Tank Assembly (VTA) Eight    cubic foot   floodable volume, portable assembly which receives LP   air   from   the DACC -  Diver    Air   Storage System (DASS) Two assemblies, each consisting of  four racks. One assembly for   diving operations. One assembly for    recompression operations. AIR   CONTROL -  Chamber Reducing Station (CRS) Reduces HP    air   from    the DASS and distributes LP   air   to   the    recompression chamber, -  Diver    Air   Control Console (DACC) Reduces DASS air   from HP    to   LP   and distributes LP   air   to   diver's volume tank. Provides three pneumo gages for   depth monitoring. AIR   FLOW -  Deck Hoses Provide air   flow   connections between components. -  Interconnecting Hoses Provide air   flow   connections between DASS racks. 1-7
