Elements contain preservative solution, therefore the permeate from the first hour of operation should be discarded. If the operating conditions in this document are not followed, no warranty of the element is honoured
Keep elements moist at all times after initial wetting. Permeate water obtained from first hour of operation should be discarded in order to flush the protective solution in the elements. CSM elements should be immersed in a protective solution during storage, shipping or system shutdowns to prevent biological growth and frost damage.
The standard storage solution contains one (1) weight percent sodium bisulfite or sodium metabisulfite (food grade). For short term storage of one week, one (1) weight percent sodium metabisulfite solution is adequate for inhibiting biological growth.
