When replacing your SJ-40 Classic salt cell, take this opportunity to make sure it is sized correctly. Sizing your salt cell properly is key to making sure you will not need to supplement with additional chlorine or shock your pool, and also extends the lifespan of your cell. The industry recommends using a salt cell with a max capacity of 1.5-2 times the actual size of your pool (more is better). The SJ-40 Classic is manufacturer rated for a maximum capacity of 40,000 gallons.
This replacement salt cell for the SJ-40 Classic is 100% compatible with original systems (no software/firmware issues). The SJ-40 Classic cell has the same length, threading, and cable connection for direct replacement.
To get the most life out of your salt cell and to keep your pool running without unexpected interruptions, make sure it is sized correctly, maintain correct water balance, and be sure and inspect your cell at least every 3 months for leaks, debris, and calcium scale. Be sure to follow instructions in the product manual and clean the cell as often as the system indicates.
