Neptune NDC Chlorinator


  • The product must be installed in accordance with AS/NZS 3000 Wiring Standards and must be installed
    at least 3.5m away from the pool.

  • Salt levels range between 3000-4000ppm (ideally 3500ppm). Salt levels below 3000ppm and
    above 4000ppm may damage equipment and void any warranty.

  • A shut-off valve on the inlet or outlet of the cell housing is NOT recommended. If a valve is required,
    it is recommended to install a non-return valve.

  • If you perform a backwash manually (without using the Backwash function on the chlorinator) you must
    turn the chlorinator’s output down to the lowest percentage setting via the “Chlor Setting” function.

  • The pump rating must not exceed 8amps.

  • We DO NOT recommend the use of valves on the inlet or outlet of the cell housing. If you do use a valve
    it is important that the valve cannot deadhead (lock closed) while the pump is running. It is the installer’s
    responsibility to ensure some form of flow control is installed in this instance and it disables the pump.


  • Do not permit children, or persons with reduced physical, sensory or mental capabilities to use or perform maintenance on this product. To reduce the risk of accidents or incidents, service on the unit should only be performed by your local Pool Pro Professional.

  • Never cover the chlorinator unit with towels or similar. The chlorinator has air vents to keep it cool. Covering the vents may cause damage to the chlorinator.

  • The chlorinator should always be in an undercover area away from the elements.

  • The chlorinator should never be in a closed shed or similar environment near chemicals or fertilisers. Fumes from chemicals and fertilisers may cause damage to the chlorinator and may void the warranty.


  • Annually check all plug connections are tight and in sound condition.

  • The cell may require cleaning if it contains debris or is being used in an area with hard water. Hard water can cause calcium build-up on the cell, the sensor, or the cell plates.

  • Periodically turn the chlorinator off and apply an insect surface spray on the WALL or POST that the chlorinator is mounted to, to keep insects from entering the chlorinator unit. DO NOT spray directly into the air vents or on the chlorinator unit.

Neptune pH Controller


  • The product must be installed by a qualified person in accordance with AS/NZS 3000 Wiring Standards.

  • The pH controller should be installed in the correct pool zone and connected to supply via a power outlet
    that is protected by a residual current device (RCD) having a rated residual operating current not exceeding
    30mA. The power outlet should have a degree of protection suitable for the pool zone.

  • The pH in your swimming pool will slowly rise due to factors such as alkalinity, the addition of fresh water
    and as sanitiser is produced in a salt/mineral water system. A rise in pH reduces the effectiveness of the
    sanitiser, so it is important to ensure that the pH remains in the correct range.

  • The pH of the water can be lowered by the addition of hydrochloric acid – and if your system has the optional
    pH control, this can be done automatically. The Neptune pH Controller uses an algorithm to calculate how
    much acid needs to be dosed to correct the pH.

  • While the algorithmic pH control is effective, it does not measure pH. pH testing should be undertaken
    manually on a weekly basis to ensure the pH is correct.

  • When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID. Always wear the
    appropriate safety equipment specified by the acid supplier when handling acid.

  • The system uses a 1:3 Acid:Water mix ratio (e.g. with a 20 litre drum add 15 litres water then 5 litres acid).
    It is important to use this mix for the correct acid volume to be added.

  • Test your swimming pool water on a regular basis and take your pool water sample to your local pool professional at least twice a month.


  • The pH controller case contains live components internally. There is a danger of electric shock if opened. If the power cord is damaged then it should be replaced by the manufacturer, their agent or similar qualified person, to avoid a hazard.

  • To reduce the risk of injury, do not permit people (including children) with lack of experience and knowledge, to use this appliance unless they have been given supervision or instruction concerning use of the appliance.

  • To reduce the risk of accidents or incidents, service on the unit should only be performed by a qualified pool service professional, after disconnecting it from the mains power supply.


  • Injection Point on Injector Valve:  Check the injection point periodically, by looking through the CLEAR faucet tee, for build-up of solid matter at the end of the clear flexible PVC tubing. This could only occur from contaminants in your acid container and the result is a blockage hindering the flow of acid and reducing the life of the pump tube and roller block. While unscrewing the BLACK lock nut, take care not to lose the rubber O-Ring.

  • Lubricate Squeeze Tube: Lubricate the pump squeeze tube every 3-6 months. Use a silicone-based lubricant only as petroleum-based lubricants will cause damage to the tube and rollers.

  • Replace Squeeze Tube: Depending on usage, the squeeze tube may need replacement after 1-2 years of use. Before replacing, please ensure that the suction and injection tubes are empty. To change the squeeze tube, please follow the instructions included with the replacement kit. Only use our original sized commercial grade Tygon® Norprene® tube as incorrect sizing will result in early failure of the Tri-Roller Block.
