5. Prepare a chlorine solution using 1/4 cup of household bleach (sodium hypochlorite
solution) to one gallon (3.785 liters) of water in a container. Prepare one gallon of
solution for every 15 gallons of tank capacity. This will result in a residual chlorine
concentration of 50 ppm in the water system.
If a 100-ppm concentration is required, use ½ cup of household bleach with one gallon
of water to prepare the chlorine solution. One gallon of the solution should be used for
each 15 gallons of tank capacity.
6. Put the sanitizer solution in the fresh water tank. Place the end of the clear plastic tub-
ing (found inside the basement access panel or at the water pump) into a container of
chlorine solution.
Fresh water tank sizes vary by model; contact your dealer or
Customer Service for your specic tank size.
