NOTE

Horizontal runs must also have an anti-siphon air vent (standpipe) install ahead of the hori-

zontal 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 in-

stallation, it is the responsibility of the installer to ensure the drain pan(s) captures all con-

densate, 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.
