insulate traps and lines if located above a living area.

NOTE: The unit is shipped from the factory with the horizontal
drain connections capped as for vertical installations. For
horizontal installations, remove the caps and place them on the
vertical drain connections to keep an airtight installation.
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 3/4- -in. (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.
NOTE: To avoid drainage problems, test the primary drain line by
slowly pouring water into the pan. Check piping for leaks and

proper condensate drainage. Using the secondary drain as
explained in the previous note provides further protection against
overflow due to a clogged primary drain.
NOTE: In applications where return air humidity levels stay at
70% or above for a prolonged period of time, condensation can
form on the bottom of pan and drip.

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 (See Fig. 5).
