TM 5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 Section II.  LOCATION 17-13.    A  complete  housing  kit  is  available  for  the  500 KW  generator  set  and  should  be  used  when  the  unit  is installed outdoors on a pad.  Without the housing kit, the generator set may be installed indoors on a pad.  Both the indoor and outdoor pads should be fitted with twelve spring-loaded shock mounts for mounting the generator set. 17-14.  The location of the unit is governed primarily by its    related    systems    and    proximity    to    the    incoming electrical  service.    Weather  conditions  will  also  affect both  location  and  the  accessory  equipment  required  to provide   proper   system   operation.      Locations   where extreme ambient temperatures occur should be avoided.  Where the generator set must be exposed to low  temperature  ambients,  the  integral  engine  heater may be used to assist starting. 17-15.  Whether located indoors or outdoors, preventive maintenance     is     an     important     consideration     when selecting  or  designating  a  generator  set  location.    In addition   to   the   control   cubicle,   the   following   service points should be accessible to the operator: a. Air cleaner b. Primary fuel filter c. Secondary fuel filter d. Lube oil dip stick e. Lube oil filter f. Lube oil drain g. Fan belt adjustment h. Radiator filler opening i. Cooling system drains j. Fuel tank drain k. Hand-hole covers l. Removal of oil -pan m. Removal of rocker covers n. Battery servicing and removal o. Starter p. Battery charger q. Diode removal from generator endbell. 17-16.      Before   final   plans   are   made   for   locating   a generator set, the following points should be considered for both housed and unhoused units: a. Mounting  provisions  must  be  strong  enough  to support the set and related equipment. b. Vibration    should    be    effectively    isolated    and dampened to reduce noise and prevent damage. c. Area should be clean and dry and not subject to flooding. d. Area  should  be  large  enough  to  provide  easy access    for    servicing    and    repair,    and    free movement of cooling air (see figure 17-1). e. The   set   should   be   in   close   proximity   to   the auxiliary fuel tank. f. For generator sets installed indoors: (1) Ventilation should be available in the area with a minimum amount of duct work and which  will  maintain  set  temperature  in  a range for efficient engine operation. (2) Exhaust  gases  should  be  expelled  safely out of and away from the structure. Section III.  MOUNTING THE GENERATOR SET 17-17.    The  500  KW  generator  set  should  be  mounted on a substantial level base, preferably class B concrete with a design strength of 2500 psi. 17-18.  For generator sets enclosed 17-2
