Operating Information
- For design range, consult Toray technical bulletin, design guidelines, computer programs, or an application specialist. Failure to follow operating limits may void the warranty.
- Elements are treated with a 1% by weight percent sodium metabisulfite solution and vacuum bagged. For short-term storage or system shutdown, immerse elements in a 1% by weight percent sodium metabisulfite (food grade) solution in permeate to prevent biological growth.
- Permeate from the first hour of operation should be discarded.
- Customers are responsible for effects of incompatible chemicals; their use will void the warranty.
