Condensate Drain; 3/4" FPT
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
do not field-install a trap in the drain line. Units with a condensate pump will
require a field-supplied trap downstream from the pump. The
drain line must comply with all applicable national, state and local plumbing
codes. (If condensate pump is ordered piping is out top of unit).
