• The Langelier Saturation Index (LSI) of the concentrate must be negative to minimize the posibility of calcium scale formation on the membrane surface. At start-up the first two hours of permeate should be discarded because of element preservative. Storage conditions should be less than: <100F, dry, in original carton and not in direct sunlight.
