Figure 7-3.—Schematic drawing of a steam table. open  or  lift  the  bleeder  valve.  Figure  7-3  is  a  typical schematic drawing of a steam table. Notice the steam table’s  piping  system  in  this  figure. The food service division is responsible for routine preventive  maintenance  of  all  mess  deck  equipment. Any major troubleshooting, repairs, or overhauls are the responsibility  of  the  repair  or  auxiliary  division.  You should  advise  the  division  responsible  to  submit  all requests  for  repairs  and  parts  replacements  on  Ship’s Maintenance Action Form, OPNAV 4790/2K. GALLEY  EQUIPMENT Galley  equipment  must  be  maintained  in  a  safe, sanitary,  and  economical  way.  Enginemen  maintain  this equipment,  and  they  frequently  tram  the  food  service personnel on how to properly operate the equipment. It is always a good practice to post operating instructions near  the  equipment.  This  will  help  to  ensure  that  the operators do not abuse the machines. You may be called on to help inspect galley equipment.   You can also help determine  the  type  of  maintenance  and  the  extent  of repairs required to keep the equipment safe and efficient. Remember,  the  medical  department  is  responsible  for conducting   sanitary   inspections. The   supply department  is  responsible  for  keeping  food-handling equipment  clean.  And,  the  engineering  department  is responsible  for  maintaining  the  operation  of  this equipment. REFRIGERATORS  (SELF-CONTAINED) Galley refrigerators will not have any problems if the user will do the following: -  Allow  proper  clearance  in  the  back  of  the refrigerator.  The  refrigerator  must  have  a distance  of  at  least  4  inches  away  from  the bulkhead.   Any   obstruction   will   reduce   the airflow required for an air-cooled condenser. Do not overload the refrigerator. Properly   store   foods   with   space   for   air circulation. Follow  the  MRC  for  routine  maintenance  like defrosting  and  cleaning. Do  not  use  any  sharp  objects  like  knives  or scrapers  when  defrosting  the  refrigerator.  This  is not an acceptable procedure for removing frost buildup  on  a  refrigerator. When repairing or overhauling a refrigerator, refer to the manufacturer’s manual. “Refrigeration System,” Chapter 516 of NSTM contains general procedures on how to maintain or repair a self-contained refrigerator. Follow  all  the  necessary  safety  precautions  when handling and disposing of a refrigerant! Figure 7-4.—An arrangement of steam-jacketed kettles. 7-6
