Page 7: Piping Insulation
CHBC(X) fan coil units require a minimum trap of 1-1/2 inches provided in the drain line to assure proper drainage. HBC(X) and PHBC(X) fan coil units may be located where the return air space is large enough that a negative pressure is not present, however, a trapped condensate line is recommended in case a negative condition should occur, the unit would drain properly. - Page 8 PIPING Determination of Right-Hand/Left-Hand References FIGURE 1.
