Warning
High Voltage Electrocution Hazard
Hazardous voltage can shock, burn, cause serious injury
and or death. To reduce the risk of electrocution and or
electric shock hazards:
•Only qualified technicians should remove the panel
•Replace damaged wiring immediately
•Insure panel is properly grounded and bonded

AquaRite S3 Overview
The AquaRite S3 offers the following features:
•Can generate chlorine using a broad range of salt concentrations from 1200 PPM to
8000 PPM
•Can control and schedule a Hayward Variable Speed (VSP) pump using the internal
RS-485 connection, a Pentair VSP using a Hayward HLPMPCONV converter (sold
separately) or a single speed pump using a Hayward Smart Relay (sold separately)
•Can control a gas heater, heat pump or any other heater that uses a low voltage
on/off remote connection (requires Hayward water temperature sensor sold
separately)
•Inputs for water and air temperature sensors (temperature sensors sold separately)
•Connection for flow switch used to detect water flow (flow switch sold separately)
•Connection for pool cover detection (lowers chlorine production when the pool is
covered)
•Can be powered by either 115 or 230 VAC
•Offers recirculation freeze control which turns on the filter pump automatically to
prevent freezing (requires Hayward air temperature sensor sold separately)

AquaRite S3: How It Works
6
•The AquaRite S3 Salt Chlorine Generator is designed to
convert 99% pure salt into chlorine gas (CL2(g)).
•When CL2(g) is dissolved in water it creates Hypochlorous
Acid (HOCL) to sanitize the pool.
•The conversion occurs in the electrolytic cell, also known
as the cell (used throughout this guide).
•Power is sent from the AquaRite S3 control center to the
cell when chlorine production is scheduled (based on time
percentage).
•When power is applied to the cell, conductive plates
produce a field; which in-turn establishes an
electrochemical reaction between chloride ions & the
water to create Hypochlorous Acid.
