(shown in vertical configuration)
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 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
¾-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 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 installed ahead of the waste line to prevent escape of sewer
gases (Fig. 15).
CAUTION
!
PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in property damage.
Provide trap with air gap in drain line when connecting to waste (sewer)
line.
