TM 5-6115-590-12 CHAPTER 4 ORGANIZATIONAL MAINTENANCE INSTRUCTIONS Section I.  Service Upon Receipt of Material. 4-1.  Inspecting and Servicing the Equipment a.  Inspection. (1)    Examine  power  unit  identification  plate for positive identification of power unit. (2)    Visually  inspect  exterior  of  power  plant for  evidence  of  damage  that  may  have  occurred during storage or transportation. NOTE Check for plastic indicator tabs on fire extinguisher (fig.  1-1),  trigger  and  nozzle.    If  indicator  tabs  are missing,    replace    fire    extinguisher    with    a    new extinguisher. (3)  Release tarpaulin cover straps, carefully roll   tarpaulin   and   secure   on   top   of   power   plant. Open   battery   access   and   storage   compartment door   (fig.      1-1),   condenser   compartment   access doors, condenser air outlet doors (fig.  1-1 and fig. 1-2), refrigeration compressor compartment access door  (fig.  1-2),  conditioned  air  outlet  compartment access door (fig. 1-2), and refrigeration compartment  access  door  (fig.    1-1).    Remove  all accessory components stowed in the compartments.          Visually     inspect     all     removed accessory components for damage and check that all   required   accessory   components   are   with   the unit.    Visually  inspect  compartment  interiors  and components    installed    in    the    compartments    for possible    damage    caused    by    stowed    accessory components,  for  accumulations  of  debris  or  other foreign   material,   and   for   evidence   of   corrosion. Carefully   inspect   cooling   fins   of   condensers   and evaporators   for   evidence   of   corrosion,   damage, and accumulation of foreign material. (4)  Open instrument panel access door (fig. 1-1),  conditioned  air  system  circuit  breaker  panel access   door   and   air   temperature   control   panel access  door  (fig.    1-1).    Check  that  all  controls  or switches   are   in   the   off   or   neutral   position   and instruments are indicating the de-energized position.  Visually inspect all instruments, switches, indicating  lamps,  and  circuit  breakers  for  damage, legibility of markings, and for evidence of corrosion. (5)        Remove    water    compartment    access panel  (fig.    1-1),  conditioned  air  electrical  control components access panel, fuel and oil compartments    access    panel,    engine    and    skid access panel (fig.  1-2), engine turbine section and heat exchanger access panel, and heat exchanger compartment    access    panel.        Visually    inspect compartment   interiors   for   damage,   evidence   of corrosion   and   accumulations   of   foreign   material. Inspect  wiring  components  for  frayed  or  otherwise damaged insulation, burns, and corrosion.  Inspect plumbing lines and fittings for evidence of damage, leakage, and corrosion. Inspect all components for secure  installation,  damage,  evidence  of  damage, leakage, and corrosion. Inspect all components for secure  installation,  damage,  evidence  of  leakage, and corrosion. (6)  Check all exhaust openings in top of unit for obstructions and for damage. (7)      All   damage   or   deficiencies   that   could affect operation of the power unit shall be corrected before  operation  of  the  power  unit.    Damage  or deficiencies that would not affect operation immediately  shall  be  noted  and  corrected  as  soon as possible. WARNING Either  Lead-Acid  or  Nickel-Cadmium  batteries may be used in this equipment.  Injury or death may result if the Potassium Hydroxide electrolyte  is  added  to  the  Lead  Acid  battery. Also  do  not  add  Sulphuric  Acid  to  the  Nickel- Cadmium battery. WARNING Battery    electrolyte    is    very    corrosive.    Wear rubber   gloves,   apron   and   face   shield   when handling leaking batteries.  If battery electrolyte is  spilled  on  clothing  or  other  material,  wash immediately   with   clean   water.      If   spilled   on personnel    start    flushing    the    affected    area immediately with large amounts of clean water. Continue    flushing    until    medical    assistance arrives. b.  Battery Servicing. NOTE The    power    plant    is    shipped    In    two    different configurations- non-winterized and winterized.  The non-  winterized  unit  has  Lead-Acid  batteries  and will operate down to -25°F.  The winterized unit has Nickel-Cadmium batteries and will operate down to -65°F.
