Description

Hayward AquaRite S3 Salt System 40K AQRS340

The Hayward AquaRite S3 salt system 40k is a complete chlorine generation system designed for in‑ground residential pools up to 40,000 gallons, delivering consistent, automated sanitization with minimal day‑to‑day maintenance.

As the next evolution of the AquaRite platform, the S3 builds on one of the most widely trusted salt systems in the industry, offering a streamlined design and dependable performance for modern pool setups.

Part of Hayward’s TurboCell S3 “Clear” line, this system introduces a transparent cell design that allows for easier inspection and ongoing system monitoring—helping pool owners stay ahead of scale buildup and maintain efficient operation.


What This AquaRite S3 Salt System 40K Does

The AquaRite S3 uses electrolysis to convert dissolved salt into chlorine whenever your pool’s circulation system is running. Chlorine output is adjustable at the control panel, allowing the system to maintain consistent, automated sanitization without the need for regular manual dosing.

Paired with the included S340 TurboCell, this system is rated for in‑ground pools up to 40,000 gallons when properly sized, installed, and maintained.


The “Clear” Advantage

The AquaRite S3 is part of Hayward’s TurboCell S3 “Clear” line, designed to improve visibility, flexibility, and long-term ease of use compared to traditional salt systems.

Flexible Salt Operation (800–8000 ppm)

Unlike most salt systems that require a narrow operating range, the AquaRite S3 is designed to operate across a wide range of salt levels—from approximately 800 ppm to 8000 ppm.

This flexibility makes it easier to achieve and maintain ideal salt levels without the need for precise adjustments. It also allows for lower-salt operation (around 2000 ppm), reducing overall salt content in the pool while still maintaining effective chlorine generation.

Clear TurboCell Design

The S3 TurboCell features a transparent housing that allows for quick visual inspection of the cell plates without disassembly.

This clear design makes it easier to monitor scale buildup and overall condition, helping simplify routine maintenance compared to traditional enclosed cell designs.

Optional Omni Automation Upgrade

The AquaRite S3 platform is designed with future expansion in mind.

With an optional upgrade to Hayward Omni automation, the system can be integrated to control your pool equipment—including pump, heater, and salt system—from a single interface. This allows for centralized control at the equipment pad or remotely through a mobile device.


Designed for Reliable Operation

The AquaRite S3 is built to deliver consistent chlorine production across a wide range of pool conditions, supporting stable water chemistry throughout the swimming season.

Its simplified system design and durable components are intended for long-term use, helping reduce the need for frequent adjustments while maintaining steady performance day after day. The wide operating range of the system also allows it to continue functioning effectively even when conditions vary, reducing the likelihood of downtime caused by minor fluctuations in salt levels or water balance.

Designed for residential pool environments, the AquaRite S3 provides dependable operation with straightforward maintenance, making it a reliable choice for homeowners looking for consistent, low-intervention sanitization.

Free In‑Store Hayward Salt Cell Testing (Buy With Confidence)

Not sure if your salt cell has actually failed? Other factors can mimic a “dead cell,” including water chemistry issues, scaling, or even a faulty control board.

Lakeshore Pools offers a genuine Hayward salt cell testing station in‑store. Bring in your Hayward salt cell and we’ll test it at no charge to help confirm whether:

  • Your salt cell is still working properly
  • It’s truly at end‑of‑life and needs replacement

Beyond pass/fail results, testing can also provide a practical indication of chlorine production strength, helping you make a more informed decision. This removes the guesswork so you can move forward with confidence.

These resources outline proper installation, electrical requirements, salinity ranges, output settings, diagnostics, and long‑term maintenance recommendations.
