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 a
nd local plumbing
codes. (If condensate pump is ordered piping is out top of unit).
