Search turned up empty. My old T-15 cell died last year after 7+ years (Summer operation only, pump timer on ~1/3 time, chlorinator set to ~50%)
I replaced it with a Hayward TurboCell940-CUL extended life cell, which I understood was the same as a T-15, just supposed to last longer. I bought it last year but never installed it since the old T-15 was barely holding on so I planned to start fresh this year. There was a note on the 940 cord about the importance of setting the Hayward controller Box to the settings for for the 940, but my controller box is old, firmware version 1.4, so it doesn't seem to have any way to change the settings for different cells. I thought I read last year that it didn't matter with the old boxes. The cell reads a NaCl level of 3000 on the controller box, agreeing with an external salt reading.
When generating, it reads 24.9 volts, 4.73 A, so it should be generating FC well. However, I can't get my FC over 3 with 100% generation, even though I always used to use only 35-70% generation setting and run the pool around 4-5. Everything else is in the normal range. TA ~80, Ca~350, pH 7.8. Stabilizer normal too.
The other thing is this: I used to check the chorinator by comparing water returning to the pool to the regular pool water & finding the FC level about 2-3 higher than the pool. Now I find the FC level 0.5-1 higher than the pool sample. It just doesn't seem to be generating as well as the old T-15.
I should add that the water looks great and CC is 0. The only other thing is that I replaced my 15 year old main pump - although it's still a 3/4 HP, the new one seems to flow ~45-50 GPM on my flow gage, vs. the 40 GPM of my old pump.
Thanks for any insight. I'm concerned when we get the warmer weather my chlorinator won't be able to keep up or that I may have some sort of counterfeit cell? I bought it from a discount pool place (and can't find the receipt!!! Argh!!!)
