Peggy said: "Not only sub-par wiring, but sea water calcium carbonate buildup on the electrodes, can prevent the unit from treating. The electrodes have to be cleaned periodically (up to 4x/year in warm waters)...which does NOT require opening it up, but only a solution of muriatic acid and water used according to directions in the manual." We don't have a manual. Can you elaborate a bit? Where are these electrodes? What do you do with that solution of muriatic acid and water? Thanks!

If your Lectra/San is the current MC model, you can download and print it from the Raritan website at website at http://www.raritaneng.com. If it's an earlier model, you can get one by calling Raritan at 800-352-5630 x 6. > Can you elaborate a bit? Where are these > electrodes? In the treatment unit. Treatment units haven't changed much since the L/S wa invented over 25 years ago...only the controllers have changed. So you can see where everything in the treatment unit is in the exploded drawing in the manual on the website > What do you do with that solution of muriatic acid and > water? There are specific detailed instructions for cleaning the system with muriatic in the manual. Do not attempt it till you have those directions because you can damage the unit if you don't follow them.
