Condensate Drain Connection
The condensate drain connection is 1 1/8" O.D.S. copper and
is located on the same end of the unit as the condenser water
connections. The drain is internally trapped at the factory
requiring no external trap. The condensate line should be
pitched away from the unit with a minimum slope of 1/8" per
foot.
Drain pans and the drain trap should be kept clean by peri-
odic cleaning. A cleanout is provided as standard in the trap
to aid in cleaning.
