How to fix decimal salt reading on Hayward AquaRite 900?
If the salt reading is displayed as a decimal number, press the Diagnostic Button once. Then, slide the power switch from "Auto" to "Super Chlorinate" and back to "Auto". Wait 15 to 20 seconds. Your pool's salt level will then be displayed in parts-per-million.
What to do if the High Salt LED is illuminated on my Hayward AquaRite 900 Portable Generator?
Ensure that the correct Turbo Cell model has been selected. Check the salt level in your pool or spa. If the salt level is too high, lower it by draining some pool water and replacing it with fresh water until the salt concentration reaches recommended levels.
What to do if Check Salt LED is illuminated or flashing on Hayward AquaRite 900 Portable Generator?
Make sure the correct Turbo Cell model is selected. Check the salt level in the pool or spa. If the salt level is low, add salt according to the provided chart. Before adding large quantities of salt, it's advisable to have your salt level professionally checked.
What to do if the No Flow LED is illuminated on my Hayward Portable Generator?
If the AquaRite senses a no-flow condition, it stops generating chlorine. Check that the flow switch is correctly plugged into the connector at the bottom of the control unit and that the wire isn't cut or damaged. Ensure you have at least 12" of straight pipe before the flow switch. If there is adequate flow but the LED remains on, verify that the arrows on the flow switch (on top of the hex) point in the direction of flow.
What does it mean when the Inspect Cell LED is illuminated on my Hayward AquaRite 900 Portable Generator?
If the "Inspect Cell" LED is illuminated, make sure that the correct Turbo Cell model has been selected. Remove and inspect the cell for scale. If scale is present, follow the directions for cell cleaning. If the pool has the proper amount of salt and the "Inspect Cell" LED remains illuminated, the cell may be worn and require replacement.
How to stop Inspect Cell LED flashing on Hayward Portable Generator?
If the "Inspect Cell" LED is flashing, ensure that the correct Turbo Cell model has been selected. Inspect and clean the cell according to the provided directions. Once you're done, press the "diagnostic" button for 3 seconds to stop the "Inspect Cell" LED from flashing.
Why is the Generating LED flashing on my Hayward Portable Generator?
The AquaRite will stop generating if the pool water temperature is too high or too low. To override this, switch the main switch to SUPER CHLORINATE. The AquaRite will then run at maximum output for the rest of the current pump cycle or for 24 hours, whichever comes first.
How to fix Power LED not on Hayward AquaRite 900 Portable Generator?
Check to ensure either 120VAC or 240VAC input power is connected to the proper screw terminals at the AquaRite control. Verify the input voltage using a voltmeter. If there is input power, the fuse may have blown. The AquaRite is protected by a 20 amp mini ATO fuse located on the circuit board above the cell connector.

This document is the owner's manual for the Hayward AquaRite 900 series Electronic Chlorine Generator, specifically models AQR940 and AQR925.
The AquaRite 900 series is an automatic chlorine generation system designed for pool and spa sanitation. It operates by converting a low concentration of salt (sodium chloride) in the pool water into free chlorine, which effectively kills bacteria and algae. This process continuously recycles the chlorine, reducing the need for manual addition of sanitizing chemicals. The system is suitable for residential swimming pools up to 40,000 gallons (150,000 liters) for the AQR940 model, and up to 25,000 gallons (95,000 liters) for the AQR925 model. The actual chlorination required varies based on bather load, rainfall, temperature, and pool cleanliness. Hayward explicitly states that the AquaRite is not recommended for generating bromine.
The manual emphasizes several critical safety precautions. Users must read and follow all instructions, use only copper conductors, and disconnect all AC power during installation. Children should not operate the product without close supervision. Hayward salt systems are designed and certified as complete systems; using untested, uncertified generic cells or circuit boards with genuine Hayward products will void the warranty and can lead to premature product failure. A non-genuine Hayward replacement salt chlorination cell will void any applicable warranty. The device requires proper grounding to an "Earth Ground" terminal with a continuous copper wire and bonding to the local common bonding grid using an insulated or bare copper conductor (not smaller than 8 AWG US / 6 AWG Canada). All field-installed metal components within 3 meters of the pool, spa, or hot tub must also be bonded to the equipment grounding bus. The product must be used only in accordance with the label's directions, as using it under unsafe conditions is an offense under the Pest Control Products Act.
The AquaRite 900 series is designed for 120/240 VAC power input. It includes a Turbo cell, flow switch, and cell unions for plumbing. The electrolytic cell and flow switch tee fitting are designed for 2" (51mm) PVC pipe, with adapters available for 1½" (38 mm) plumbing. The control unit is housed in a raintight enclosure suitable for outdoor mounting, requiring a minimum horizontal distance of 5 ft. (2 meters) from the pool/spa. It must be mounted vertically on a flat surface with knockouts facing downward, ensuring the four sides are not blocked to allow for heat dissipation. The AquaRite is protected by a 20 amp mini ATO fuse located on the circuit board.
Maintaining proper water chemistry is crucial for the AquaRite's performance and longevity. Recommended ideal levels (per The Association of Pool and Spa Professionals - APSP) include:
The AquaRite features a Main Switch with three positions:
The flow switch and cell should be plumbed in the return line to the pool/spa, preferably downstream of all other pool equipment (filter, heater, solar). Specific configurations (#2 or #3) are recommended for pool/spa combination systems with spillover to prevent over-chlorination during "spa only" operation. A minimum of 12" (25cm) straight pipe run is required before the flow switch, and the arrow on the flow switch must point in the direction of water flow. Unions for the electrolytic cell should be tightened by hand.
The AquaRite can be wired for stand-alone operation to the LOAD SIDE of the filter pump timer, or directly to 120/240VAC power when used with Hayward, Pentair, or Polaris automation controls. Jumpers on the PCB configure the unit for 120VAC or 240VAC. For Canadian models, the AquaRite must be connected to a circuit protected by a Class A ground fault interrupter. The electrolytic cell and flow switch cables connect to specific ports on the bottom of the enclosure. For automation controls, a 4-wire connection is used, and one AquaRite unit must be configured as "primary" while others are "secondary."
The manual provides solutions for common problems such as the "Power" LED not being on (check power, fuse), "Generating" LED flashing (water temperature too high/low), "No Flow" LED illuminated (check flow switch connection, pipe run, flow direction), "Check Salt" LED (low salt), "High Salt" LED (high salt), and "Inspect Cell" LED (reduced cell efficiency, scale, or worn cell). It also addresses the display of "-Pcb-" and all 4 red/yellow LEDs illuminated, indicating a possible Printed Circuit Board fault requiring service. A table outlines basic pool maintenance requirements for free chlorine, pH, alkalinity, salt, stabilizer, calcium, and electrolytic cell inspection/cleaning.
Hayward offers a limited warranty (effective 02/12/16) for its AquaRite 900 series chlorination products. Private residential swimming pools in the US and Canada receive a four (4) year warranty for defects in materials and workmanship. Commercial pools in the US and Canada receive a one (1) year warranty. All accessories and replacement parts have a one (1) year warranty. The warranty is not transferable and applies only to the original owner. Proof of purchase is required for warranty service. Exclusions include damage from improper installation (including on pools larger than the product rating), failure to operate/maintain according to the manual, failure to maintain pool water chemistry, tampering, accidents, abuse, negligence, unauthorized repairs, environmental factors (fire, flood, lightning, freezing, external water, degradation of natural stone), and the use of non-genuine Hayward replacement salt chlorination cells. The manual also details a 90-day extended warranty available upon product registration via smartphone or online.
