Product details
The CaliMar CMARCFS40-1Y is an aftermarket replacement salt cell for the Zodiac Nature2 Fusion Soft system, rated for pools up to 40,000 gallons. It is compatible with the Zodiac R0503000 cell and the FSOFT1400 system.
What it matches
CaliMar lists two cells for the Nature2 Fusion Soft line. The CMARCFS40-1Y covers the 40,000 gallon FSOFT1400 and corresponds to Zodiac cell R0503000. The smaller CMARCFS12-1Y is for 12,000 gallon FSOFT700 systems and corresponds to R0502800, so the two are not interchangeable. This listing is the 40,000 gallon cell only.
Brand and compatibility
This is a CaliMar part. CaliMar states that these cells are not manufactured, produced or marketed by Zodiac and that it is not affiliated with Zodiac. The Zodiac names and part numbers are given only to show which system the cell is compatible with. The pool size rating is the same as the cell it stands in for.
Before you order
Read the part number printed on your existing cell. If it reads R0503000, or your system is an FSOFT1400, this is the match. If it reads R0502800, you need the 12,000 gallon cell instead. The UPC is 922001900410.
