When installed outdoors, the setshould be a housed unit, or an enclosure should be builtto protect it from inclement weather. Don't overlook thepossibility of spring flooding or high water level duringstorms if the set is to be located in a low area such as awater front or basement installation.17-84. Screens or other protection should be providedto safeguard against potential fire hazards and/oroperational problems which can be caused by rodents,insects, birds, etc. They have been known to live orbuild nests inside enclosures and even insidegenerators.17-85.Whenever possible, install the set in an areawhich can be quickly reached for repair in case ofmalfunction. Service entrances should be large enoughto permit removal of large components such as engine,radiator, or generator in the even major overhaul orreplacement becomes a necessity.17-86.Service items that are hard to reach will not beproperly maintained. Make sure ample room is providedaround the set especially at points requiring regularattention. Figure 17-25 illustrates the location of itemsrequiring regular service. An item requiring dailyattention must, of course, be made more accessiblethan one requiring service every 5000 hours.NOTEFor standby units it is important that servicing isperformed on a calendar basis since it may takeyears to accumulate any significant number ofhours to the set. Failure to do this may result inthe set not starting or operating properly whenthe unit is most needed.17-87.
