VI − REFRIGERANT LINE NOISEIt is important to properly isolate the refrigerant lines toprevent unnecessary vibration. Line set contact with thestructure (wall,ceiling or floor) causes some objectionablenoise when vibration is translated into sound.The following illustrations demonstrates procedures whichensure proper refrigerant line set isolation. Figure 17shows how to install line sets on vertical runs. Figure 18shows how to install line sets on horizontal runs. Figure 19shows how to make a transition from horizontal to vertical.Finally, figure 20 shows how to place the outdoor unit andline set.REFRIGERANT LINE SETSHOW TO INSTALL VERTICAL RUNS(new construction shown)NOTE-Similar installation practices should be used if lineset is to be installed on exterior of outside wall.Outside WallIMPORTANT-Refrigerant linesmust not contact wall.Vapor LineLiquid LineWood BlockBetween StudsWire TieInside WallStrapLiquid LineSleeveVapor Line (wrappedwith Armaflex)Wire TieOutside WallWood BlockWire TieStrapCaulkPVC PipeFiber GlassInsulationSleeveIMPORTANT-Refrigerantlines mustnot contact structure.FIGURE 17Page 16
