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).
