* The element diameter (dimension C) is designed for optimum performance in Osmonics pressure vessels. Other pressure vessel dimension and tolerance may result in excessive bypass and
Notes:
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.
