AutoPilot PPC1 Replacement Salt Cell for Pool Pilot Salt Systems
OEM AutoPilot Replacement Cell for Smaller Pool Pilot Systems
The AutoPilot PPC1 Replacement Salt Cell (formerly RC-35) is a genuine OEM replacement salt chlorinator cell designed for compatible AutoPilot Pool Pilot Digital, ChlorSync Generation 2, and Pool Pilot Evolve systems. The PPC1 is commonly used with PPM1 manifold configurations and is the correct replacement cell for systems that require the PPC1 cell size.
Your salt cell is the core of the chlorination system. It converts dissolved salt into chlorine through electrolysis, helping maintain clean, clear, comfortable pool water. When an existing PPC1 cell becomes worn, scaled, or reaches the end of its service life, replacing it with the correct OEM AutoPilot cell helps restore dependable chlorine production and proper salt system performance.
ATB Fitment Note
The PPC1 is the replacement cell only. It does not include the power center, manifold housing, cell cord, tri-sensor, unions, or plumbing components unless specifically stated. Always match the replacement cell to your existing AutoPilot cell part number, manifold, and system configuration before ordering.

What Does the PPC1 Cell Do?
The PPC1 is the electrolytic cell that produces chlorine inside your compatible AutoPilot 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 PPC1 can restore dependable chlorine generation when the rest of the system is functioning correctly.
ATB Before-You-Replace Checklist
Before replacing the cell, make sure the issue is actually cell-related. It is smart to check:
- Salt level with an independent meter, not just the control display
- Water chemistry including stabilizer, phosphates, pH, alkalinity, and calcium hardness
- Cell cord condition for burn marks, corrosion, melting, or loose connections
- Flow through the manifold and filter cleanliness
- Cell scaling or calcium buildup on the plates
- Tri-sensor condition and connection
- System messages or warnings on the power center
Compatibility and Fitment
The AutoPilot PPC1 Replacement Cell is intended for compatible AutoPilot salt chlorine generator systems that use the PPC1 cell configuration. It is commonly used with the PPM1 manifold and smaller AutoPilot salt systems.
Compatible System Families
| Pool Pilot Digital | Compatible when the system is configured for the PPC1 replacement cell |
| ChlorSync Generation 2 | Compatible when using the correct PPC1 cell and matching AutoPilot setup |
| Pool Pilot Evolve | Compatible with Evolve systems using the PPC1 / PPM1 configuration |
Because AutoPilot systems can vary by cell size, manifold, power center generation, controller programming, wiring, and previous replacement history, the safest way to confirm fitment is to match your existing cell label and system configuration before ordering.
Not every Pool Pilot, ChlorSync, or Evolve system uses the PPC1 cell. Please confirm your existing cell part number or send us photos of your current cell, manifold, and power center if you are unsure.
When Should You Replace the PPC1 Cell?
- 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 power center, cord, tri-sensor, flow, and water chemistry are not the root issue
PPC1 vs Other AutoPilot Replacement Cells
The PPC1 is the smaller replacement cell in the Pool Pilot Evolve / Pool Pilot lineup. It is intended for systems that use the PPC1 cell configuration and is commonly paired with the PPM1 manifold. Larger systems may use a different PPC cell size, so matching the existing setup is important.
| Cell | Typical Match | Best For |
| PPC1 | PPM1 | Smaller residential pools |
| PPC3 | PPM3 | Mid-size residential pools |
| PPC4 | PPM4 | Larger residential pools |
| PPC5 | PPM5 | Largest residential pools and highest chlorine demand |
ATB Expert Tip
A new salt cell will not fix every chlorination issue. Low salt, poor water balance, low stabilizer, high phosphates, bad flow, a damaged cell cord, a tri-sensor issue, or a failing power center can all look like a bad cell. If you are unsure, send us a photo of your current cell label, manifold, and control box so we can help confirm the correct replacement before you order.
Installation Notes
The AutoPilot PPC1 should be installed according to AutoPilot instructions and matched to the proper manifold and power center configuration. Before installation, shut off system power and inspect the cell cord, manifold condition, 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. If the old cell failed due to excessive scale, poor water chemistry should be corrected so the new cell is not damaged prematurely.
Frequently Asked Questions
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 PPC1?
The PPC1 is a genuine AutoPilot replacement salt cell for compatible Pool Pilot systems. It is the cell responsible for generating chlorine from dissolved salt in the water.
What systems does the PPC1 work with?
The PPC1 is compatible with select Pool Pilot Digital, ChlorSync Generation 2, and Pool Pilot Evolve systems that use the PPC1 cell configuration. Always match your existing cell and system setup before ordering.
Does the PPC1 include the manifold or power center?
No. The PPC1 is the replacement cell only. The manifold, power center, tri-sensor, cell cord, unions, and plumbing components are separate unless specifically included in a bundle.
What size pool is the PPC1 for?
The PPC1 is commonly used with PPM1 AutoPilot Evolve systems rated up to 30,000 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 PPC1 the same as RC-35?
PPC1 is commonly associated with the AutoPilot replacement cell size that many pool owners previously knew as RC-35. Because AutoPilot systems and labels can vary by generation, the safest confirmation is to match your existing cell label, manifold, and controller configuration before ordering.
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 PPC1 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 PPC1 replacement cell is a genuine OEM AutoPilot replacement part.
