The manual for a "CS7110" Intex SWCG is here:

I don't think there is a CS711.

Let me know of the lower salt level fixes things, however the Intex SWCG have only a 1 year warranty -- and if you use BOOST mode (AKA the 'kill my SWCG unit quickly' mode!) much you'll be lucky if it lasts 1 month past warranty.
