\nOVERVIEW  \nThis chapter builds upon the information presented in Chapter 7,coveringmechanical symbology consisting of heating,ventilating,and air conditioning(HVAC);plumbing;and piping symbols.It is important for the electrical worker tounderstand these symbols to avoid making electrical runs where ducts and pipesare to go.On a commercial or industrial job,large pipes and HVAC duct work usuallytake precedence over electrical runs due to the fact that it is easier to reroute anelectrical conduit than it is an HVAC duct or plumbing pipe.It is important not tomake print-reading mistakes that would require costly rework.After completing this chapter,you will be able to:·Explain why the electrical worker needs to understand mechanical symbology.OLSb  \nOBJECTIVES  \n·Recognize and interpret various common plumbing,piping,and HVAC symbols.  \n# PLUMBING SYMBOLS\n\nMost architects and engineers usethe ANSI standard graphic symbols orminor modifications of these standardsfor plumbing.As mentioned previously,if the print symbols used are nonstan-dard,a print legend should be suppliedExamples of these standard symbols areshown in Figures 8-2 and 8-3.  \n# Toilet Symbol\n\nPlumbing symbols are used on residen-tial,commercial,and industrial prints.Plumbing symbols usually representthe device in a somewhat pictorial way.These symbols may appear in both planand elevation views(Figure 8-1).  \nPlan  \n# Plumbing Fixture Symbology\n\n\n| Plumbing Fixture Symbology   |  |\n| --- | --- |\n| Washroom Fixtures   | BATHTUB,RECESSED(B)  \u003Cbr>BATHTUB,CORNER(B)

the different piping runsand materials being piped(Figure 8-6).  \nPiping runs are often shown in iso-metric drawing form.These piping iso-metrics help indicate the relationshipsof the various
