Odor is an indication that it isn't working
When the Lectra/San is installed correctly and working properly, there should be no odor...none inside the boat, nor should the discharge stink. It kills bacteria--and therefore odor--by charging the ions in salt water with electrical current and does not require the use of ANY chemical. In fact, directions emphasise that NO chemicals should go into a Lectra/San--no tank chemicals, no bleach or anything that contains bleach, no household chemical bowl cleaners, no Lysol, PineSol or ANY cleaning product other than Raritan C.P. So if you've used anything else, even to clean your toilet, you've damaged the electrode pack, which is the most likely reason you have odor from it. However...If you haven't used any chemical products in the toilet or L/S, it may only mean that it needs cleaning...'cuz sea water calcium carbonate buildup on the electrodes can "insulate" them from the salt in sea water, preventing the unit from working.Unless your unit is so old that it still has the original dial timer, there should be lights on the control that tell you "low salt" (also can be caused by mineral buildup on the electrodes), low voltage (corroded terminal, low battery, blown fuse)...Apparently you've never seen a manual for it, or you'd already know most of what I've just said. If you have one, I suggest you read it...if you don't, you can download one from the Raritan website at http://www.raritaneng.com/products/waste_treatment/lectrasan.htmlWhatever the reason, your Lectra/San obviously isn't working. Read the manual...and on Monday give Vic Willman at Raritan a call to discuss the possible reasons and how to correct the problems. 800-352-5630 x 6
