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