T M    1 0 - 3 8 3 5 - 2 1 9 - 14 c.  Air   and   Vapor   Evacuation .   (figure   2-11)   After   removal   of   residual   fuel   from   hoseline,   any   air   and   fuel   vapors must   be   evacuated   so   that   hose   can   be   folded   flat   in   flaking   box. W A R N I NG (1) (2) (3) (4) (5) (6) Do   not   smoke,   carry   an   open   flame,   or   use   any   heat-producing   device   near hoseline   during   fuel   displacement   and   vapor   evacuation   operations.   Hearing   and eye   protection   must   be   worn. Breakdown   hoseline   into   1000-foot   (300m)   sections   by   disconnecting   leading   and   trailing   couplings. Seal   of   the   trailing   end   of   first   hose   section   (1)   with   a   pipe   cap   (2),   clamp   (3),   and   gasket   (4)   and   secure with   bolts   (5)   and   nuts   (6). Ball   inlet   (7)   should   still   be   attached   to   leading   end   of   first   hose   section   (8)   with   air   compressor   line   (9) attached.   Disconnect   air   compressor   line   (9)   and   attach   ejector   jet   assembly   (10)   to   ball   inlet   (7). Connect   compressor   line   (9)   to   ejector   jet   assembly   (10). Apply   air   pressure   to   ejector   jet   assembly   (10).   The   rapid   passage   of   air   through   ejector   will   create   a partial   vacuum   in   the   hoseline.   It   is   necessary   to   operate   compressor   for   approximately   10   minutes   to clear   each   1000   feet   (300m)   of   hoseline. When   hose   has   flattened   apply   hose   clamp,   shut   off   air   compressor   and   remove   ball   inlet   (7)   from   hose. Install   pipe   cap   (2)   and   secure   with   pipe   coupling   clamp   then   remove   hose   clamp. Figure   2-11.   Air   and   Vapor   Evacuation. 2 - 3 5
