The Hayward AquaRite W3AQR15 is a complete salt chlorination system for in-ground pools up to 40,000 gallons. Includes the AquaRite 900 control unit, W3T-CELL-15 TurboCell, flow switch, and plumbing hardware. NSF and ETL certified.

Hayward AquaRite W3AQR15 Salt Chlorination System for In-Ground Pools Up to 40,000 Gallons

The W3AQR15 is a complete kit for converting an existing in-ground pool to salt chlorination. Everything needed for a standard installation is in the box: no separate cell purchase, no sourcing parts from multiple suppliers.

The system taps into your existing return line after the pump and filter. No additional plumbing runs required.

Hayward AquaRite W3AQR15 Key Features

Adjustable output (0-100%) - Dial chlorine production up or down based on pool demand without buying extra chemicals.
Superchlorinate function - Boosts output to 100% for 24 hours to handle algae, heavy bather loads, or post-storm recovery. Returns to normal automatically.
Automatic cell self-cleaning - The controller periodically reverses electrode polarity to dislodge calcium scale, extending cell life in hard-water areas.
Dual voltage (120V/240V) - Same unit accepts both voltages; no transformer swap needed.
Digital LED display - Shows salt level, output percentage, water temperature, and specific diagnostic codes for fault conditions.
Weatherproof enclosure - Rated for permanent outdoor installation; mounts directly to the wall at the equipment pad.
Automation compatible - Integrates with Hayward ProLogic, AquaLogic, and OmniLogic platforms if you add automation later.
NSF + ETL certified - NSF certified per NSF/ANSI Standard 50 for chlorine delivery rates; ETL safety certified for electrical components.

How the AquaRite W3AQR15 Converts Pool Salt into Chlorine

Pool water passes through the W3T-CELL-15 TurboCell in your return line. A low-voltage DC current from the control unit splits dissolved salt molecules via electrolysis, producing hypochlorous acid (active chlorine) directly in the water. After sanitizing, the chlorine converts back to salt and the cycle repeats. Salt is not consumed; only small periodic top-ups are needed to replace what leaves through splash-out, backwashing, and rain dilution.

Target salt level is 3,200 ppm (operating range 2,400 to 3,400 ppm). At that concentration, most swimmers cannot taste or smell the salt.

Because salt-generated chlorine produces no cyanuric acid carrier or chloramine byproducts, the water typically feels softer and is less irritating to eyes and skin than pools dosed with trichlor tablets.

AquaRite Salt System Comparison: W3AQR15 vs W3AQR3 vs W3AQR9

All three open-line AquaRite kits use the same AquaRite 900 control unit. Only the included TurboCell size differs.

Model	Max Pool Size	Included Cell	Max Daily Output
W3AQR15 (this model)	40,000 gal.	W3T-CELL-15	1.45 lbs/day
W3AQR3	15,000 gal.	W3T-CELL-3	0.53 lbs/day
W3AQR9	25,000 gal.	W3T-CELL-9	0.75 lbs/day

Sizing note: The W3AQR15 is the largest open-line AquaRite kit. You cannot oversize a salt system; if your pool is smaller than 40,000 gallons, the W3AQR15 will simply run at a lower output percentage and the cell will experience less wear, extending its service life.

Hayward AquaRite W3AQR15 Frequently Asked Questions

Does the W3AQR15 work with above-ground pools?

No. The W3AQR15 is rated for in-ground pools only. For above-ground pools, Hayward makes the AquaTrol line, which is designed for the lower flow rates and plumbing configurations of above-ground setups.

Can I upgrade to a larger TurboCell later without replacing the control unit?

Yes. The AquaRite 900 control unit is compatible with the W3T-CELL-3, W3T-CELL-9, and W3T-CELL-15. The W3AQR15 ships with the largest available TurboCell; if you ever need to downsize to a smaller pool, the same control unit works with the smaller cells. The control unit detects the installed cell size automatically.

Do I still need to add other chemicals to a salt pool?

Yes. The AquaRite handles chlorination only. pH, total alkalinity, calcium hardness, and cyanuric acid still need to be monitored and adjusted. pH tends to rise gradually in salt pools due to sodium hydroxide produced during electrolysis, so periodic acid additions are standard practice.

What type of salt should I use?

Use high-purity sodium chloride (NaCl) at 99.8% purity or better: pool salt, evaporated granulated salt, or non-iodized food-grade salt. Avoid iodized salt, potassium chloride, rock salt with organic debris, and any salt containing anti-caking agents such as sodium ferrocyanide, which can stain pool surfaces.

What does the "Check Cell" alert mean?

It is a maintenance reminder that activates after approximately 500 cumulative hours of operation, not necessarily a fault. Inspect and clean the cell, then reset the alert per the instructions in the owner's manual. If it reappears quickly after resetting, or if chlorine output has dropped, scale buildup or a failing cell should be investigated.

Can the W3AQR15 connect to a Hayward automation system?

Yes. The AquaRite 900 integrates with Hayward ProLogic, AquaLogic, and OmniLogic platforms via a dedicated data cable. No additional hardware is required beyond the automation system itself.
