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 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).
Piping outlet locations through
the plenum are the same as the unit.
See below for descriptions and
connection sizes.
