UNIT DAMAGE HAZARD
Failure to follow this caution may result in product
damage.
DO NOT BURY MORE THAN 36 IN. OF REFRIGERANT
TUBING IN GROUND. If any sec tion of tubing is buried,
theremustbea6in.verticalrisetothevalveconnections
on the outdoor unit. If more than the recommended length
is buried, refrigerant may migrate to cooler buried section
during extended periods of unit shutdown, causing
refrigerant slugging and possible compressor damage at
start- up.

CONDENSATE DRAIN LINE CONNECTION
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in property
damage.
When installing over a finished ceiling and/or living area,
install a field- fabricated secondary condensate pan under
the entire unit.
CAUTION
!
The coil is designed to dispose of accumulated water through
built- in condensate drain fittings. It is recommended that PVC
fittings be used on the condensate pan. Do not over- tighten.
Finger tighten plus 1 - 1/2 turns. Be sure to install plastic plug in
unused condensate drain fitting. Two 3/4 inch female threaded
pipe connections are provided in each c oil condensate pan.
A trap is not necessary on the condensate line if on the supply
air side of furnace. For any modular air handler use
recommended minimum of 4” trap, is required. Consult local
codes for additional restrictions or precautions. If local codes
require a trap then the following guidelines are suggested to
assure proper drainage. Install a trap in condensate line of coil
as close to the coil as possible. Make trap at least 3 inches (76
mm) deep and no higher than the bottom of unit condensate
drain opening (See Figure 10). Pitch condensate line 1 inch
(25.4 mm) for every 10 ft. of length to an open drain or sump.
Make sure that the outlet of each trap is below its connection to
condensate pan to prevent condensate from overflowing the
drain pan. Prime all traps, test for leaks, and insulate traps and
lines if located above a living area.
EXPLOSION HAZARD
Failure to follow this warning could result
in personal injury or death.
Provide trap with air gap in drain line
when connecting to waste (sewer) line.

Figure 10 - Condensate Trap
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 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 (See Figure 11)
