This 28-gauge galvanized steel basin functions as the system's primary safety brain for moisture management, engineered to catch overflow from the primary evaporator coil or air handler. Specifically designed for horizontal furnace installations and attic air handlers, the DP-F1643 ensures that any internal blockages in the main drain line are contained within the pan, preventing the catastrophic ceiling damage and mold growth that occur when condensate spills onto building materials. \u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine M\u0026amp;M Part Number DP-F1643:\u003c\/strong\u003e Guaranteed professional-grade fit featuring a 16-inch by 43-inch footprint specifically sized for standard residential fan coils.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty 28 Gauge Galvanized Steel:\u003c\/strong\u003e Manufactured with high-tensile strength metal that resists sagging under water weight and prevents the cracking common in plastic alternatives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminate Rust and Leak Issues:\u003c\/strong\u003e Replaces aging, corroded pans or brittle plastic trays that fail over time, restoring the structural integrity of your secondary containment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Moisture Safety Monitoring:\u003c\/strong\u003e Features a pre-installed 3\/4\" PVC drain fitting that allows for easy connection to a secondary drain line or an emergency float switch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced Hemmed Edges:\u003c\/strong\u003e Engineered with rolled edges for superior rigidity and safety, preventing sharp metal edges from snagging insulation or cutting technicians during install. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Details\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e M\u0026amp;M Manufacturing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e M\u0026amp;M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e DP-F1643\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 16\" Width x 43\" Length x 2\" Depth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 28 Gauge Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type:\u003c\/strong\u003e 3\/4\" PVC Female Adapter (Pre-installed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Horizontal Furnace \/ Air Handler Secondary Drain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e Meets standard building codes for secondary HVAC containment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 6.5 lbs \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e🛠️ HVAC Depot Pro Tip\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTake a Picture First —\u003c\/strong\u003e Before sliding the new DP-F1643 under your unit, photograph the clearance space and the existing primary drain line. Having a visual record of the \"dry\" state of the pan is essential for future diagnostic checks; if you see water in your photo later, you know the primary drain is clogged. When installing, ensure the pan is pitched slightly toward the PVC outlet to prevent standing water from becoming a breeding ground for biological growth. Always install an emergency float switch (like a Safe-T-Switch) inside the pan to automatically shut down the system if water is detected. \u003c\/p\u003e\n\u003cp\u003eCross-Reference\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperseded Parts:\u003c\/strong\u003e DP-1643, DP-F-16-43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLegacy Drawing Numbers:\u003c\/strong\u003e 540-1643, 83011, 83015\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquivalent Brands:\u003c\/strong\u003e DiversiTech 230-DP1643, Rectorseal 83210, Jones Stephens D601643, DiversiTech Metal Pan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eModel Compatibility\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorizontal Air Handlers\u003c\/strong\u003e (Suffixes: 1.5 Ton, 2 Ton, 2.5 Ton, 3 Ton Units)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Furnaces\u003c\/strong\u003e (Suffixes: Upflow\/Horizontal 40k, 60k, 80k, 100k BTU)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEvaporator Coils\u003c\/strong\u003e (Suffixes: Case and Uncased Horizontal A-Coils)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMini-Split Ducted Units\u003c\/strong\u003e (Suffixes: 18k, 24k, 30k BTU Horizontal Chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"MnM","offers":[{"title":"Default Title","offer_id":52451496460651,"sku":"662766542187","price":77.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/DrainPan.jpg?v=1772227454","url":"https:\/\/tophvacparts.com\/products\/m-m-dp-f1643-secondary-drain-pan-with-pvc-fitting-16-x-43-28-gauge-galvanized-steel","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
