Water is evenly distributed across the top tray and flows by gravity over the Water Panel evaporator. As dry air passes through the moisture‑laden panel, moisture is picked up and carried back into your living spaces. Regular maintenance helps keep evaporation steady and reduces the chance of performance gaps during peak heating months.\u003c\/p\u003e\n\n  \u003ch2\u003eWhat’s inside\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eWater Panel (10)\u003c\/li\u003e\n    \u003cli\u003eIn-line Strainer (4004)\u003c\/li\u003e\n    \u003cli\u003eNozzle (4184)\u003c\/li\u003e\n    \u003cli\u003eDrain Spud (4223)\u003c\/li\u003e\n    \u003cli\u003eYellow Orifice (4231)\u003c\/li\u003e\n    \u003cli\u003eScale Control Insert\u003c\/li\u003e\n    \u003cli\u003eWater Distribution Tray\u003c\/li\u003e\n    \u003cli\u003eFeed Tube\u003c\/li\u003e\n    \u003cli\u003eOwner's Manual\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch2\u003eFit, dimensions and replacement cadence\u003c\/h2\u003e\n  \u003cp\u003eThe Water Panel actual dimensions are 9.75\" H × 9.5\" L × 1.75\" W, ensuring an optimal fit for your unit.
