NOTE: If unit is located in or above a living space, where damage
may result from condensate overflow, a field-supplied,
external condensate pan should be installed underneath the
entire unit, and a secondary condensate line (with an
appropriate trap) should be run from the unit into the pan.
Any condensate in this external condensate pan should be
drained to a noticeable place. As an alternative to using an
external condensate pan, some localities may allow the
running of a separate 3/4 inch (19 mm) condensate line (with
appropriate trap) per local code to a place where the
condensate will be noticeable. The owner of the structure
must be informed that when condensate flows from the
secondary drain or external condensate pan, the unit requires
servicing or water damage will occur. To further protect
against water damage. Install a float switch to shut the unit
off if the water in the secondary pan gets too high.

Waste Line Connection
If the condensate line is to be connected to a waste (sewer) line, an open
trap must be in stalled ahead of the waste line to prevent the escape of
sewer gases.
Failure to follow this warning could result in personal injury or death.
Provide trap with an air gap in the drain line when connecting to waste
(sewer) line.
