Frequently Asked Questions
Should I replace the cord at the same time?
AutoPilot recommends fitting a new cell cord when you replace the cell. Reusing a worn cord can void warranty coverage on the new cell, and cord failure is a common cause of what looks like cell failure.
Which cell do I need for a larger pool?
The PPC3 and PPC4 cover larger pool volumes. Match the cell to your pool size and to the AutoPilot control unit you already have — fitting an undersized cell means it runs constantly and wears out early.
Does this replace an RC-35 or SC-36?
Yes. The PPC1 is the current replacement for the RC-35, RC-22 and SC-36 cells.
How long does a salt cell last?
Typically three to five years depending on run hours, water chemistry and how well calcium scaling is managed. Keeping salt and pH in range and cleaning scale off the plates extends cell life considerably.
Why is my cell producing less chlorine?
Usually scale build-up on the plates, low salt level, cold water, or a cell reaching end of life. Inspect and clean the plates before concluding the cell has failed.
Who should install it?
A qualified pool professional or a competent owner. The system must be isolated and depressurised before the cell is removed.
Frequently asked questions
What is the part number for this salt cell?
AutoPilot lists this cell under part number PPC1. Quote PPC1 when you cross-reference against your equipment manual, an existing cell, or a parts diagram, so you are comparing the same revision.
How do I confirm this fits my system?
Match the part number stamped on the cell you are replacing, or look it up in the parts list for your AutoPilot 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.
How do I keep a salt cell working well?
Keep salt level and pH within the range your manual specifies, and inspect the plates for calcium scale each season. Scale insulates the plates and cuts chlorine output long before the cell is genuinely worn out.
Do I need to add salt after fitting a new cell?
Not because of the cell itself, but test and correct salt level before you start the new cell. Running a cell at low salt shortens its life.
Is there a warranty on this salt cell?
It carries the standard AutoPilot manufacturer warranty. The terms are set by the manufacturer, and fitting a new cell cord at the same time helps protect coverage. Keep the receipt and packaging until you have confirmed correct operation.
