Keep in mind too, that you have excessive heat in Phoenix, which will create additional chlorine demands. There's merit in suggesting to upsize your system. You will have the extra capacity, if needed, and longer cell life.

The AutoPilot offers the ability to adjust the Cell Power output, in addition to adjusting the Purifier % setting, so that you can control overchlorination conditions. That is, with our maximum gallon rated cell, which is based on the highest of 3 different Cell Power outputs from the Digital control unit, we offer the ability to derate it. Going with the largest cell, RC-52 (52K gallons) but set on Cell Power 1 (5 amps) instead of Cell Power 3, (8 amps), you can decrease the amount of chlorine generated, then fine tuning it to maintain your desired level by adjusting the Purifier % setting.

But then again, I'm sure there are many Aquarite systems with the larger cell on smaller pools, to know that the combination works in Phoenix.

You'll love your salt chlorine generated pool!
