Autopilot Digital DIG 220/SC-60 questions

[Mr.Shaky]

Just saw this tip to increase the salt level as the water gets colder. Can you explain why that'd help?

Also, I've read that generating chlorine in cold water will shorten the cell life. Is that true?

One more question: With the SC-60 cell, what are the voltage/current values for proper operation?

Thanks much

As the water gets colder the resistance goes up. Increasing the salt level lowers the resistance back down to what it was before.

AutoPilot units work fairly well with cold temperatures, some other brands refuse to function when the water is cold. You only want to run at rather low percentages when the water is cold. As long as you are doing that it won't have any significant impact on cell life.

When working normally, you should see numbers around these:
Cell Power 1 = 5.0 amps
Cell Power 2 = 6.5 amps
Cell Power 3 = 8.0 amps
SC-36 = 17 - 21 volts
SC-48 = 23 - 27 volts
SC-60 = 21 - 25 volts

Any risk of damage from running a 24 hour "boost" when the temp is around 50-60 degrees?

I would not recommend doing that. It won't "damage" the unit, but it will be a much less efficient use of the SWG than it would be at a warmer temperature.

If you are shocking the pool, you really want to raise the FC level very quickly. A SWG is not a good way to do that. SWGs are designed to add chlorine slowly and uniformly, which isn't what you want when shocking the pool.

Infrequent Boost cycles will not harm the overall cell life. However, it should only be used for an increase of your chlorine residual (but not a "superchlorination" dosage) IF you have a larger volume pool and the Automatic Temperature Compensation is not maintaining your FC residual.
