Field pitch a min. of 1/8" (3.2mm) per ft. (305mm). Units without
a condensate pump have a factory-supplied trap in the unit, so a
field trap should not be added. Units with a condensate pump will
require a field-supplied trap downstream from the pump. The
drain line must comply with all applicable codes. (If condensate
pump is ordered piping is out top of unit).
