Zodiac – Complete LM2-15 cell – R0759200

The Zodiac R0759200 is a complete replacement electrolytic cell for the Zodiac Clearwater LM2-15 salt chlorination system. The cell is the heart of any salt chlorinator: it uses electrolysis to convert dissolved salt in the pool water into free chlorine, providing continuous and automated sanitation without the need to manually dose liquid or granular chlorine. This genuine Zodiac replacement cell restores full chlorination capacity to an LM2-15 system when the original cell has reached the end of its service life.

The cell assembly is supplied complete, meaning it includes the electrode stack and housing as a ready-to-install unit. The titanium electrodes are coated with a precious-metal oxide layer that catalyses the electrolytic reaction efficiently at low voltage. Over time, this coating depletes through normal use, which is why periodic cell replacement is a standard part of salt chlorinator maintenance. Installing a genuine OEM replacement cell ensures the system controller communicates correctly with the cell and that chlorine output ratings remain accurate.

Technical characteristics and compatibility

The R0759200 is specifically designed and rated for the LM2-15 model within the Zodiac Clearwater LM2 range. The LM2-15 designation refers to a cell rated for pools up to approximately 15 cubic metres (15,000 litres), making it suited to smaller residential pools and spas. This cell supersedes the earlier part number W202031, so owners of older LM2-15 units using the legacy part number can use R0759200 as the confirmed direct replacement.

The cell integrates directly with the Zodiac Clearwater LM2 control unit and its associated plumbing housing. No modification to existing pipework or wiring is required when replacing like-for-like. As with all electrolytic cells, water chemistry — particularly salt concentration, pH, and stabiliser levels — must be maintained within the manufacturer’s recommended ranges to achieve rated chlorine output and to maximise electrode lifespan.

Suitability and buying guidance

This replacement cell is intended for residential pool owners and pool service professionals who operate a Zodiac Clearwater LM2-15 salt chlorination system. It is the correct choice when the existing cell shows signs of reduced chlorine output, coating degradation, or physical damage, and when the control unit and plumbing housing are otherwise in good working order. If your system carries the model designation LM2-15 or previously used part number W202031, the R0759200 is the confirmed OEM replacement. For larger pool volumes, Zodiac offers the LM2-24 (R0759200 equivalent for 24 m³) and LM2-30 cells, so it is important to match the cell rating to your pool size and existing system model before ordering.
