Emaux CyberSync Salt Chlorinator User Manual

Overview

The CyberSync Salt Chlorinator is a smart salt chlorination system designed for above-ground and in-ground pools. It produces chlorine through electrolysis, helping maintain clean, comfortable water while reducing the need for manual chemical handling.

It is intended for swimming pools and spas only. The system is also built to work as a connected pool control station, so it can manage compatible equipment such as a circulation pump, dosing pumps, lighting, and other linked devices through the control panel or mobile app.

Detailed description

The CyberSync Salt Chlorinator turns dissolved salt into chlorine using electrolysis inside a titanium cell. Chlorine output is adjusted from the controller by changing the electrical current that passes through the cell, which gives the user more control over sanitation levels.

The system does not balance pool water on its own. It generates chlorine from salt water, so the pool still needs regular testing for salt, pH, alkalinity, calcium hardness, and chlorine level. In practice, the chlorinator works best as part of a properly maintained pool circulation system.

The control platform includes a main LCD screen, menu navigation, Wi-Fi pairing, pump control, dosing control, and status indicators for flow, pool cover, temperature, and chlorine production. The app connection adds remote monitoring, scheduling, and alerts.

Safety

This unit must be installed according to local electrical wiring rules and connected to a proper disconnecting means. It should never be powered through an extension cord, and the supply must be protected by grounding and an RCD or GFCI with a rated residual current not greater than 30 mA.

Before any servicing, unplug the unit and allow it to cool for at least 15 minutes. Never unplug the cell cable while the system is running, and do not open the enclosure until power has been disconnected and the unit has cooled down.

The chlorinator must operate only with water flowing through the cell. The pump must be running and valves must remain open, because trapped pressure in the cell enclosure can create a serious burst hazard.

Children should only use the appliance under supervision, and cleaning or maintenance should not be performed by children without supervision. The device is for pool and spa sanitation only and must not be used for drinking water.

Only one pump and one underwater light may be connected to the unit, and the connected pump load must not exceed 8A.

Setup and operation

Before adding salt, set the multiport valve to Filtration or Recirculation, then start the filtration pump. Spread the salt evenly through the pool or ballast tank instead of piling it in one spot. After adding salt, keep the filtration system running for 24 hours so the salt can dissolve fully.

The recommended salt range is 1000 to 3000 ppm. Too little salt can shorten cell life, while too much salt can damage stainless steel fittings and accessories. The manual recommends 1 to 3 kg of salt per 1,000 litres of water as a general guide.

Use clean pool-grade salt with about 99% sodium chloride. Avoid rock salt, iodized salt, and salt with excessive anti-caking agents or yellow prussiate of soda, since impurities can reduce cell life.

The control interface shows operating status, clock sync, flow switch condition, pool cover condition, low-temperature warnings, electrolysis output, and relay status. The electrolysis screen lets you choose the installed cell size and adjust output percentage to reduce chlorine production when needed.

Available electrolysis settings include a selected cell size of 20 g, 30 g, or 40 g, a level adjustment for reducing duty cycle, winter mode that lowers production to 85%, and water modes for Normal, Hard, or Intensive conditions. Up to four schedule entries can be created for chlorine production.

The dosing section supports three dosing pumps. Each pump can be set to Schedule, On, Off, or Deactivated. A priming function runs the connected dosing pump continuously while the button is held, which helps check the dosing tube before normal operation resumes.

The pump control section is reserved for the circulation pump and can be set to On, Off, Schedule, or Deactivated. Switch 1 to 3 can be assigned to devices such as lights, UV equipment, heaters, or other compatible loads, with up to four schedule settings available.

To use the Smart Life app, install the app on a mobile device, create an account, log in, then power on the chlorinator. From the device menu, open the settings page, press and hold the Wi-Fi pairing key for one second, and add the device in the app while the router has internet access and operates on 2.4 GHz Wi-Fi.

Some alerts shown on the display and app include low temperature, no water flow, low salt, cell check, and driver connection check. These warnings help identify when chlorine production is paused or when pool conditions need attention.

Cleaning and maintenance

The titanium cell should be cleaned when calcium scale builds up. Start by turning off the filtration system and removing the cell from its housing. Place the cell into a suitable cleaning solution while keeping the terminals out of contact with the mixture.

Leave the cell in the cleaner for about five to ten minutes for routine buildup. If deposits remain after that, a smooth plastic tool can be used to remove loose calcium without damaging the cell.

Rinse the cell with fresh water, reinstall it in the housing, tighten the collar, and return the system to automatic or timer mode. A milder dedicated cell cleaner is preferred over harsh hydrochloric acid, and heavier scale may require a longer soak of up to one hour.

If salt needs to be reduced, the only practical method is partial draining and refilling with fresh water.

Troubleshooting

• Low temperature: chlorine production can drop when water is cold because conductivity decreases.
• No flow detected: check the circulation pump, valve positions, and water movement through the cell.
• Low salt warning: add salt after confirming the pool is within the target salinity range.
• Cell check warning: inspect the titanium cell for scale or poor operation.
• Driver connection warning: verify the power driver and related wiring.

Warranty

The CyberSync Salt Chlorinator is covered by a limited warranty for the original purchaser against defects in materials and workmanship during the warranty period. The coverage begins on the purchase date and is not transferable.

The warranty excludes expendable parts and does not cover damage caused by misuse, accident, force majeure, operation outside the stated usage conditions, unauthorized parts, product modification, war or terrorism, or service performed by anyone other than an authorized reseller or agent.

Under the warranty, defective parts may be repaired or replaced with new or equivalent used parts at the manufacturer’s discretion.

Pros & Cons

• Pros: Smart app control, real-time pool monitoring, flexible pump and device scheduling, and chlorine generation from salt water.
• Pros: Adjustable output modes help match sanitation to seasonal and water conditions.
• Pros: Clear status alerts make it easier to spot flow, salt, and temperature issues early.
• Cons: Requires correct electrical installation, stable circulation, and regular water testing to perform well.
• Cons: Performance depends on maintaining proper salinity and cleaning the titanium cell when scale builds up.
