8.2 CONDENSATE DRAIN TUBING
Consult local codes or ordinances for specific requirements.
IMPORTANT:
When making drain fitting connections to the drain pan, use a thin layer
of Teflon paste, silicone or Teflon tape and install hand tight.
IMPORTANT:
When making drain fitting connections to drain pan, do not overtighten.
Overtightening fittings can split pipe connections on the drain pan.
• Install drain lines so they do not block service access to front of the unit. Minimum
clearance of 24 inches is required for filter, coil or blower removal and service access.
• Make sure unit is level or pitched slightly toward primary drain connection so that
water will drain completely from the pan. (See Figure 20.)
• Do not reduce drain line size less than connection size provided on condensate drain
pan.
• All drain lines must be pitched downward away from the unit a minimum of 1/8” per
foot of line to ensure proper drainage.
• Do not connect condensate drain line to a closed or open sewer pipe. Run conden-
sate to an open drain or outdoors.
• The drain line should be insulated where necessary to prevent sweating and damage
due to condensate forming on the outside surface of the line.
• Make provisions for disconnecting and cleaning of the primary drain line should it
become necessary. Install a 3 in. trap in the primary drain line as close to the unit as
possible. Make sure that the top of the trap is below connection to the drain pan to
allow complete drainage of pan (See Figure 37).
• Auxiliary drain line should be run to a place where it will be noticeable if it becomes
operational. Occupant should be warned that a problem exists if water should begin
running from the auxiliary drain line.
• Plug the unused drain connection with the plugs provided in the parts bag, using a
thin layer of teflon paste, silicone or teflon tape to form a water tight seal.
• Test condensate drain pan and drain line after installation is complete. Pour water
into drain pan, enough to fill drain trap and line. Check to make sure drain pan is
draining completely, no leaks are found in drain line fittings, and water is draining
from the termination of the primary drain line.
8.3 DUCT FLANGES
Field-installed duct flanges (4 pieces) are shipped with units. Install duct flanges as
needed on top of the unit. (See Figure 3.)
