What salt level should I maintain with the Neptune NDC Chlorinator?

  • The salt level operation is 3000-4000ppm and ideally is 3500ppm.

  • Salt levels below 3000ppm and above 4000ppm may damage equipment
    and void any warranty.

What tools do I need to install this chlorinator?

  • Drill with a 6mm drill bit.

  • Basic PVC fittings.

  • Hacksaw.

  • PVC Primer and PVC Cement "Type P" for pressure pipes.

  • No.2 Phillips Head screwdriver.

Do I have to do anything to my swimming pool before installing the chlorinator?

  • Have your swimming pool water tested and balanced. 

  • The ideal salt levels range between 3000ppm - 3500ppm (ideally 3500ppm).

  • For new pool installations, consult your local pool builder or your local pool shop before adding salt. Some pool builders do not recommend the addition of salt for a period of time following completion of the swimming pool.

  • Use Pool Pro Ultrafine Pool Salt or Pool Pro Premium Pool Salt at the rate of 3.5kg per 1000L of pool water. Mineral/magnesium chloride salts can also be used, including Neptune Mineral Salt. Add 20%-30% extra product for mineral/magnesium salts.

Where do I install the Power Pack?

  • The power pack must be installed outside of the pool zone, no more than 1.5m from the cell, at least 1m above ground, away from chemicals and fertilisers (fumes may damage the power pack) and in accordance with AS/NZS 3000 Wiring Standards.

  • Mount the Power Pack in a well ventilated position away from direct sunlight and rain (not in a closed unventilated shed). If mounting on a post, install a waterproof non-metal flat panel as a backing plate.

  • There may be incorrect Timer settings. Press the Power/Mode button until the chlorinator is in the ON mode. Check the Timer settings.


The chlorinator turns on then turns off.

  • The circuit breaker may be tripping. This can be due to excessively high salt levels.

  • There may be a short across the Cell plates. Check the Cell plates for any metal lying across the plates.

The chlorinator doesn't turn on at all.

  • Check the Power Pack's power cord goes into a wall outlet and the outlet is turned on.

  • Test the wall outlet with a working appliance.

  • Check the circuit breaker at the bottom of the Power Pack and press the white button to reset if it's tripped.


What should I do before installing the pH Controller?

  • Ensure your pH is balanced to the recommended level for your swimming pool surface. Ideal pH levels for concrete pools: 7.4 - 7.6. Ideal pH levels for fibreglass and vinyl pools: 7.0 - 7.2.

What tools do I need to install the pH Controller?

  • Drill with a 6mm drill bit.

  • Basic PVC fittings.

  • Hacksaw.

  • PVC Primer and PVC Cement "Type P" for pressure pipes.

  • No.2 Phillips Head screwdriver.

How do I use the pH Controller?

  • The Neptune pH Controller is controlled via your Neptune NDC Chlorinator. Simply access the pH Control menu on your Neptune NDC Chlorinator by pressing the OK button and using the + or - buttons until you reach the 'pH Control Mode' menu, and press the OK button.

My pH Controller is not turning on, what do I do?

  • Check the pH Control Mode has been turned on and set up in your Neptune NDC Chlorinator menu. Check the pH Controller's power cord is plugged in to the chlorinator's AC socket outlet.

Everything looks normal but the pH level is not changing when I test the pool water.

  • Check the acid drum is not low or empty.

The pH Controller is not running when the chlorinator is in "Auto" mode.

  • The pH Controller may have already operated for the day's timer cycle. The pH Controller will not run again if it has already completed its automatic cycle for the day.
