Operating Information and Storage
- All elements are wet tested.
- Elements are treated with a 1% by weight sodium bisulfite storage solution and then vacuum packed in oxygen barrier bags, or treated with tested feed water solution and vacuum packed in oxygen barrier bags with deoxidant inside.
- For short-term storage, shipment, or system shutdown, it is recommended that elements be immersed in a protective solution containing 500 - 1,000 ppm of sodium bisulfite (food grade) dissolved in permeate.
- Permeate from the first hour of operation shall be discarded.
- The customer is fully responsible for the effects of chemicals that are incompatible with the elements. Their use will void the element Limited Warranty.
