AutoPilot PPC2 Replacement Cell

The PPC2 is the electrolytic cell that produces chlorine inside your compatible AutoPilot Pool Pilot Nano Plus salt system. As pool water passes through the cell, dissolved salt is converted into chlorine, which sanitizes the water and helps keep the pool clean and safe for swimming.

When a salt cell becomes worn out, the system may struggle to hold chlorine levels, run at higher output for longer periods, or display production-related issues. Replacing the cell with the proper OEM PPC2 can restore dependable chlorine generation when the rest of the system is functioning correctly.

The AutoPilot PPC2 Replacement Cell is intended for compatible AutoPilot salt chlorine generator systems that use the PPC2 cell configuration. This cell is specifically for Pool Pilot Nano Plus / Digital Nano Plus systems.

Because AutoPilot systems can vary by cell size, controller generation, wiring, and previous replacement history, the safest way to confirm fitment is to match your existing cell label and system configuration before ordering.

• Your current AutoPilot salt cell has reached the end of its service life
• The system is no longer maintaining chlorine properly
• The existing cell is heavily scaled or physically damaged
• The cell has failed diagnostics or no longer produces reliably
• The system has repeated cell-related alerts after water chemistry and flow have been checked
• You want to replace the cell before peak season to avoid downtime
• You have confirmed the control box, cord, flow, and water chemistry are not the root issue

The PPC2 is different from the PPC1, PPC3, PPC4, and PPC5 cells because it is specifically tied to Pool Pilot Nano Plus / Digital Nano Plus applications. It should not be selected based only on pool size or physical appearance. Always match your existing AutoPilot cell label and controller type.

The AutoPilot PPC2 should be installed according to AutoPilot instructions and matched to the proper Pool Pilot Nano Plus / Digital Nano Plus configuration. Before installation, shut off system power and inspect the cell cord, unions, sensor area, and wiring connections for any visible damage, heat marks, corrosion, or buildup.

After installation, confirm correct water balance, proper flow, and salt level before expecting full chlorine production. Cell cords should be replaced when the cell is replaced to help prevent connection issues and avoid warranty problems. If the old cell failed due to excessive scale, poor water chemistry should be corrected so the new cell is not damaged prematurely.

Which cell cord do I need?

The correct cell cord depends on your AutoPilot power center or control box, not only the replacement cell model. Some legacy Pool Pilot / Total Control / Nano style systems use the Legacy / Nano style cord, while Pool Pilot Digital, DIG-220, Generation II, and Pool Pilot Evolve systems use the Digital / DIG-220 / Gen II / Evolve style cord. If you are unsure which version you have, send us photos of your control box label and the existing cell cord connection before ordering.

What is the AutoPilot PPC2?

The PPC2 is a genuine AutoPilot replacement salt cell for compatible Pool Pilot Nano Plus / Digital Nano Plus systems. It is the cell responsible for generating chlorine from dissolved salt in the water.

What systems does the PPC2 work with?

The PPC2 is intended for Pool Pilot Nano Plus / Digital Nano Plus systems that use the PPC2 cell configuration. It is not the standard replacement cell for Pool Pilot Digital, ChlorSync Generation 2, or Pool Pilot Evolve systems.

Does the PPC2 include the power center?

No. The PPC2 is the replacement salt cell. The power center/control box, cell cord, sensors, and other system components are separate unless specifically included in a bundle.

What size pool is the PPC2 for?

The PPC2 is commonly used with Pool Pilot Nano Plus systems rated up to 32,000 gallons when matched with the proper setup. Actual performance depends on the full system, water chemistry, run time, sunlight, bather load, and chlorine demand.

Is PPC2 the same as RC-28?

PPC2 is commonly associated with the AutoPilot replacement cell size that many pool owners previously knew as RC-28. Because AutoPilot systems and labels can vary by generation, the safest confirmation is to match your existing cell label and control box before ordering.

Do I need to replace the cell cord?

AutoPilot notes that the cell cord must be replaced when the cell is replaced to help prevent warranty issues. It is also smart to replace a cord that shows corrosion, heat damage, melting, loose connection, or wear.

How do I know if my salt cell needs replacement?

Common signs include weak chlorine production, inability to maintain sanitizer, repeated cell-related messages, visible cell wear, heavy scaling, or failed diagnostics. Other system issues can cause similar symptoms, so basic troubleshooting is recommended before replacing the cell.

Can I clean the PPC2 instead of replacing it?

If the cell is only scaled, cleaning may help restore performance temporarily. If the cell is worn out or at the end of its service life, cleaning will not restore long-term chlorine production and replacement is typically the correct solution.

Is this a genuine OEM AutoPilot part?

Yes. The PPC2 replacement cell is a genuine OEM AutoPilot replacement part.
