Installer's Guide
It is always recommended that an auxiliary drain pan
be installed under a horizontally installed air handler.
Connect the auxiliary drain line to a separate drain line
(no trap is needed in this line) and terminate according
to local codes.
NOTE: DO NOT use a torch or flame near the plastic
drain pan coupling.
NOTE: DO NOT tighten the drain pipe excessively. Sup-
port the condensate piping and traps outside the unit
to prevent strain on the drain coupling.
