NOTE
Horizontal runs must also have an anti-siphon air vent (standpipe) install ahead of the horizontal run to
eliminate air trapping. Horizontal drain lines must be pitched a minimum ¼" per foot.
Route the drain lines outside or to an appropriate drain. Drain lines must be installed so they do not block
service access to the front of the unit. 24" clearance in the front is for routine maintenance or service.
NOTE
Check local codes before connecting the drain line to an existing drainage system.
Insulate the drain lines where sweating could cause water damage. Upon completion of installation, it is
the responsibility of the installer to ensure the drain pan(s) captures all condensate, and all condensate is
draining properly and not getting into the ductwork/system.
Vertical Mounting:
When mounted vertically, the air handler's primary drain connection is located in the center of the unit. The slightly higher
drain to the left is the secondary drain.
Attach the drain connector and tighten TO THE PROPER TORQUE SHOWN PREVIOUSLY with sealant and install the
drain line.
Specifications are subject to change without notice.
