Once a month, add 2.5 lbs of potassium permanganate to the feeder tank. To add the potassium, remove the lid on your feeder tank and pour 1/2 of the 5 lb container. A 5 lb container of potassium should last approximately 2 months.
In order for the system to function properly, it is critical to maintain enough potassium in the feeder tank. To check if there is enough potassium in the feeder tank, insert a small wooden stick into the mixture. The stick should be stained a deep purple. If the stick is light pink or has no color, you must add more potassium.
The potassium pad should be rinsed out with water every 6 to 12 months. This will remove the build up of iron on the felt pad. Use rubber gloves and old cloths when doing this maintenance. The potassium will stain your hands, cloths, sinks, and any other item it comes in contact with.
The injector inside the control valve should be cleaned every 3-6 months. See cleaning your injector, or preventive maintenance section of your owners manual.
If you experience purple water from your faucets, do not drink the water. Run the tap for 15-20 minutes until the color clears. When the water runs clear, you can use the water. Call Portasoft and schedule a service call to correct the problem.
