TM 5-6115-590-12 NOTE Condenser air inlet panels and condenser air outlet doors (fig.  1-1 and 1-2) must be opened before operation of the cooled air system. (11) Bleed  air  system  connections.    Connect compressed air hose assembly (fig.  1-15, sheet 3 of 7) to compressed air outlet fitting (fig.  4-5).  Install inflation ejector assembly (fig.  1-15, sheet 3 of 7) to the inflation manifold on the inflatable shelter of the MUST hospital. Connect delivery end of compressed air hose assembly to ejector assembly for inflation of the inflatable shelter. A hose is available to furnish bleed air to the air intake filter deicer. (12) Vacuum    system    connection.      Connect vacuum  hose  assembly  (fig.    1-15,  sheet  4  of  7)  to vacuum  outlet  fitting  (fig.    4-5).    Connect  other  end  of vacuum   hose   assembly   to   shelter   requiring   vacuum service. 4-3.    Fuel  and  Lubrication  System   Depreservation and Servicing The fuel and lubrication system must be depreserved and serviced by organizational maintenance personnel as follows: a.    Open  oil  tank  access  door  (fig.    1-1),  remove filler  cap  and  dipstick  from  oil  tank  and  fill  oil  tank  with oil  as  specified,  rather  to  Lubrication  Order,  LO5-6115- 590-12.    Allow  time  for  oil  level  to  recede  as  air  is vented, then add oil until level remains at FULL mark on dipstick.  Reinstall oil tank filler cap and dipstick. b. Connect   external   fuel   system   filter   separator assembly  to  fuel  inlet  fitting  as  shown  in  figure  4-2. Connect  fuel  hose  assembly  between  fuel  supply  and filter assembly.  Check fuel lines and filter assembly for leakage.    Make  sure  that  an  adequate  supply  of  the correct  fuel  is  available  for  the  anticipated  operating period. NOTE For  initial  operation  or  at  any  time  the  no  fuel indicator  lamp  is  Illuminated,  it  will  be  necessary to  purge  air  from  the  fuel  float  tank  to  allow  the fuel level to overcome the fuel float switch before the  unit  will  start.    After  connecting  the  external fuel  source  hold  the  fuel  boost  pump  switch  ON for a few seconds to fill the fuel tank then open the oil  tank  access  door  and  press  the  button  on  the fuel float tank vent valve until fuel flows from the drain  tube  at  the  oil  tank  spill  drain  (beneath  the oil  tank  fill);  then  release  button.    The  no  fuel indicator  lamp  should  now  be  extinguished  and the    power    plant    can    be    started    by    normal procedure. c. Remove  engine  combustor  access  panel  (fig. 1-2).      Disconnect   fuel   line   from   fuel   atomizer   and connect   a   line   to   drain   overboard   into   a   suitable container (fig.  4-6).  Do not drain fuel onto the ground. d. Momentarily   place   the   master   switch   on   the instrument   panel   to   the   START   position.      Motor   the engine  by  starter  motor  action  for  10  to  15  seconds  to allow  fuel  to  discharge  from  the  overboard  drain  line until you have a good flow into the container, then place master switch to the STOP position. e.    Disconnect   and   remove   overboard   drain   line and  reconnect  engine  fuel  line  to  the  fuel  atomizer  and check  for  oil  and  fuel  leaks.    If  no  leaks  are  present, reinstall engine combustor access panel (fig. 1-2). Section II.  Movement to a New  Worksite 4-4.  Dismantling for Movement a. Disconnection of Accessory Components. (1) Disconnect all electrical cable assemblies from receptacle panel and remote power panel (fig. 2-9) and  from  shelters.    Coil  cable  assemblies  and  secure ends  for  stowage.    Remove  ground  wire  from  electrical system    ground    terminal    E2.        Close    or    install    all protective covers on connectors of receptacle panel and remote power panel.  Attempt to remove ground rod. (2) Disconnect all conditioned air duct assemblies    from    return    air    inlets    (fig.        1-1)    and conditioned air outlets (fig.  1-2).  Install covers over air inlets  and  outlets,  secure  covers  with  clamps.  Visually inspect  duct  assemblies  for  abrasions,  holes,  or  other damage.  Separate conditioned air duct assemblies from conditioned air duct coupling assemblies.  Collapse duct assemblies  and  secure  in  the  collapsed  position  with duct retaining assemblies. CAUTION Handle conditioned air duct assemblies with care to avoid damage to fabric. (3) Close  hot  and  cold  water,  and  hot  water recirculating  valves  (fig.    4-4).    Disconnect  dual  water hose assembly, and waterrecirculating hose from water inlet and outlet connection panel, and from water supply and  discharge  points.    Drain  hose  assemblies.    Coil hose  assemblies  and  secure  ends  for  stowage.    Drain power plant water system as follows. (a) Remove  drain  caps  from  hot  water tank  vent  drain,  heat  exchanger  drain,  and  surge  tank drain.    Open  the  hot  waterrecirculating  valve  and  the hot  and  cold  water  outlet  valves.    Open  the  hot  water tank  vent  valve  (fig.    1-11)  until  all  water  has  drained from system, then close vent valve. 4-13
