Hayward Swimclear 425 SQ FT Cartridge Filter

## Hayward SwimClear 425 Sq. Ft. Quad-Cluster Cartridge Filter

The Hayward SwimClear™ large-capacity cartridge filter series is engineered to deliver heavy-duty dirt-holding capacity and pristine, crystal-clear water clarity for high-demand residential or commercial inground pools. Utilizing a synchronized **Quad-Cluster™ grid of four premium reusable polyester cartridge elements**, this powerhouse model provides an expansive **425 square feet of effective filtration area**. This massive surface area captures more debris over extra-long filtration cycles, drastically reducing the frequency of filter teardowns and manual washouts.

Molded from an improved, glass-reinforced thermoplastic co-polymer, the SwimClear tank is engineered to endure brutal environmental conditions and high pressure. By eliminating the backwash cycle entirely, it stands as the premier eco-friendly, water-saving alternative to traditional sand or D.E. filters—saving you thousands of gallons of chemically treated water every single pool season.

### Advanced Hydraulic Design & Structural Engineering
*   **High-Endurance Thermoplastic Tank:** Structural outer hull is injection-molded from extra-durable, glass-reinforced co-polymer. Engineered to easily handle high-demand hydraulic loads, including heavy-pressure in-floor pool cleaning systems.
*   **Precision Bypass Prevention:** Features a heavy-duty, non-corrosive top closure plate that mechanically locks the four cartridge elements into absolute alignment. This tight seal prevents the elements from lifting or shifting under pressure, completely eliminating unfiltered water bypass.
*   **Full-Flow 2-Inch Internal Piping:** Plumbed with massive 2-inch internal water pathways. This low-resistance hydraulic path optimizes flow dynamics, reducing backpressure on your variable speed pump to maximize overall electrical energy efficiency.
*   **Rapid-Drain Maintenance Port:** Equipped with an oversized, integral 1.5-inch manual bottom drain. This large orifice allows for incredibly fast, 100% tank drainage, making seasonal flush-outs and winterization effortless.
*   **Cartridges Included:** Ships complete from the factory with one full, heavy-duty set of four (4) premium reusable polyester filter cartridges.

### ⚠️ Seasonal Maintenance, Freezing Warnings & Warranty Protections
*   **Factory Warranty Policy:** Backed by a 1-Year Manufacturer’s Limited Warranty covering structural defects in workmanship and materials. Product coverage is strictly limited to replacement parts and explicitly excludes any secondary labor costs, replacement water expenses, or pool chemical losses.
*   **Freeze Prevention Mandate:** The factory warranty **does not cover structural splitting, cracking, or plumbing ruptures caused by freeze expansion or residual ice formation**. The internal core must be drained completely via the 1.5" bottom plug and cartridges removed during winterization in cold-weather regions.
*   **Installation Integrity:** Damage resulting from improper mechanical anchoring, over-pressurization past factory specifications, or unlicensed plumbing layout configurations will instantly void all warranty protections.
