TM 5-6115-590-12 storage, all scheduled preventive maintenance services, including inspection, shall be suspended and preventive maintenance inspection shall be performed as specified herein.        Perform    quarterly    preventive    maintenance services   when   the   item   is   initially   placed   in   limited storage   and   every   30   days   thereafter.      Record   all deficiencies  and  shortcomings  together  with  corrective action taken on DA Form 2404.  Required maintenance will  be  performed  promptly  to  insure  that  the  item  is sound and ready for immediate use.  At the time of the 30  day  inspection  and  maintenance,  operate  the  item long enough to bring it up to operating temperature and insure  complete  lubrication  of  all  bearings,  gears,  etc. Operate the cold water pump for 30 seconds to prevent pump     freeze     up.          After     each     operating     period, represerve the item as outlined in paragraph 1-4 a. c.    Administrative Storage. (1)    Storage Site. (a)    Select  the  best  available  site  for  administrative storage.  Separate stored equipment from equipment in use.        Conspicuously    mark    the    are    "Administrative Storage." (b)    Covered  space  is  preferred.    When  sufficient covered space for all items to be stored is not available, priority    should    be    given    to    items    which    are    most susceptible to deterioration from the elements.  SB 38-1 should  be  used  as  a  guide  for  establishing  the  items most susceptible to deterioration. (c)    Open sites should be improved hard. stand, if available.      Unimproved   sites   should   be   firm,    well- drained, and kept free of excessive vegetation. (2) Storage Plan (a)    Store   equipment   so   as   to   provide   maximum protection from the elements and to provide access for inspection,    maintenance,    and    exercising.    Anticipate removal   or   deployment   problems   and   take   suitable precautions.  For example, strategically locate recovery vehicles, snowplows, slave units, and similar items likely to be needed on short notice. (b)    Take    into    account    environmental    conditions such  as  extreme  heat  or  cold,  high  humidity,  blowing sand, dust or loose debris, soft ground, mud, heavy snows, earthquakes or combinations thereof and take adequate precautions. (3)    General Cleaning, Painting and Preservation. (a)    Cleaning.    Clean  the  equipment  of  dirt,  grease, and other contaminates, but do not use vapor degreasing. CAUTION Do  not  direct  water  or  steam,  under  pressure against   air   cleaners,   air   duct   outlets,   exhaust outlets, unsealed electrical systems, fire control instruments,  or  any  exterior  opening  which  will damage a component. (b)    Painting.    Remove  rust  and  damaged  paint  by scraping,  wire brushing,  sanding or buffing.  Sand to a smooth finish and spot paint as necessary.  See TM 43- 0139. (c)    Preservation.          After     cleaning     and     drying, immediately  coat  unpainted  metal  surfaces  with  oil  or grease as appropriate. (d)    Weatherproofing.          Sunlight,     heat,     moisture (humidity),   and   dirt   tend   to   accelerate   deterioration. Install  all  covers  authorized  for  the  equipment.    Close and   secure   all   openings   except   those   required   for venting   and   draining.      Seal   openings   to   prevent   the entry  of  rain,  snow,  or  dust.    Insert  desiccant  when  a complete seal is required.  Place equipment and provide adequate blocking to allow for draining of water. NOTE Secure    waterproof    covers    so    u    to    prevent collection of water and to allow circulation of air to   minimize   damage   from   condensation   and excessive heat. CAUTION Place    a    piece    of    barrier    material    between desiccant   bags   and   metal   surface   to   prevent corrosion NOTE Refer to TM 740-90-1 for additional information regarding administrative storage of this equipment. Section II.  Description and Data 1-5.  Description a.    General.    This  power  plant  is  a  fully  enclosed, skid mounted, self-contained, portable unit (fig.  1-1 and 1-2).  The unit provides conditioned air (heating, cooling and ventilation), electrical power (400 Hz, 60 Hz and 24 volts DC emergency lighting power), hot and cold water, compressed air, and a vacuum system for support of the MUST    (Medical    Unit    Self-Contained,    Transportable) hospital  elements.  The  power  plant  consists  of  a  gas turbine engine power  plant,  electrical  generating  system,  conditioned air    system    (including    refrigeration),    water    system, compressed air system, vacuum system, enclosure, and accessory components for connection of the power plant to  other  elements  of  the  MUST  hospital.    The  power plant requires only an external source of fuel and water for  self-contained  operation.  It  will  operate  at  ambient temperature  from  140  degrees  F  to  -25  degrees  F  (-65 degrees   with   a   winterization   unit   installed).      Lifting, tiedown, support and 1-2
