Designed for horizontal coil installations — such as attic and crawlspace mounts — this pan sits under the coil to capture condensate and route it safely to the drain line. Because horizontal applications are especially prone to water damage, a correctly shaped factory pan with the proper slope and drain location is critical to prevent overflow and ceiling leaks.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1756028L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Horizontal (primary) condensate drain pan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Goodman \/ Amana air handlers, model WAHMS3743P4ACA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrientation:\u003c\/strong\u003e Horizontal coil installations (attic \/ crawlspace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Collects and drains evaporator condensate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAftermarket horizontal pans often miss the WAHMS coil contour and drain-port placement, creating low spots where water pools and eventually overflows.
