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.
