Operating Information
- For recommended design range, consult the latest Toray technical bulletin, design guidelines, computer design program, and/or an application specialist. Failure to strictly follow operating limits will void the Limited Warranty.
- All elements are wet tested, treated with a 1% by weight percent sodium bisulfite storage solution, and then vacuum packed in oxygen barrier bags. Alternatively, they may be treated with tested feed water solution and then vacuum packed in oxygen barrier bags with deoxidant inside.
- To prevent biological growth during short-term storage, shipment, or system shutdown, it is recommended that Toray 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.
