HORIZONTAL APPLICATIONS
Upflow and Downflow furnaces - All horizontal applica-
tions are left side only. It is always recommended that the
auxiliary drain pan be installed under a horizontally in-
stalled evaporator and/or 90% gas furnace. Connect the
auxiliary drain pan to a separate drain line (no trap is needed
in this line).
The trap must be repositioned to the exterior of the cabinet.
Remove the trap from its present location and reposition the
trap outside of the unit, through the long circular hole, next to
Right side
VERTICAL APPLICATIONS
Upflow furnace - The connection tubing for left and right
side drainage is shipped in the blower compartment. Install
the connection tubing from the trap to the side of the unit and
trim all excess tubing to avoid kinks.
Downflow furnace - The furnace is shipped with the left
side drainage setup. To change the right side drain, remove
the drain lines from the trap, rotate the trap 180° so it exits
to the right, reconnect the lines, and run a 1/2" CPVC pipe
from the trap out through the right side knock-out. Use RTV
silicone sealant to connect the CPVC pipe to the trap for ease
of removing to clean the trap.
