I have an ESC-36 and in my hardcopy manual from about 5 years ago, it says the minimum salt level should be 3000ppm and I run at 3500.
The online manual you can get says minimum is 4000 ppm and ideally 4500 ppm

As far as cleaning your cell, my hardcopy says 1 part acid to 3 parts water. The online manual says 1 part acid to 10 parts water but still has a diagram showing 3 to 1.
this is on page 10.
What are the correct levels based on these 2 conflicting manuals by them?
I am attaching the manual you can find online. You can download this small file here:
