Frequently asked questions
How many gallons is this salt system rated for?
The gallon rating is part of the model designation and is listed in the specification section above. Sizing up is normal practice: a cell rated above your pool volume runs fewer hours to hold the same chlorine level and generally lasts longer than one running at its limit.
What is the part number for this salt cell?
Nature2 lists this salt cell under part number R0502300. Quote R0502300 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
How long does a salt chlorinator cell last?
Cell life is measured in operating hours rather than calendar years, and most residential cells give several seasons of service. Life is shortened by high cyanuric acid, low water temperature operation, scale buildup on the plates, and running the cell at a high output percentage for long periods.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Nature2 equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Do I need a matching power supply or control unit?
A cell and its power centre are matched as a pair; a cell will not generate chlorine on a power supply it was not designed for. Check whether this listing is the cell only, the power supply only, or a complete system before ordering.
Is there a warranty on this salt cell?
It carries the standard Nature2 manufacturer warranty. The terms are set by Nature2, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
