Important Notes

• Permeate flow for individual elements may vary ±15 percent.
• Elements are vacuum sealed in a polyethylene bag containing less than 1.0% sodium meta-bisulfite and 10% propylene glycol solution.
• The presence of free chlorine and other oxidizing agents will cause membrane failure; damage is not covered under warranty.
• Permeate obtained from the first hour of operation should be discarded.
• For element loading, use only glycerine to lubricate o-rings and brine seal.
• These membranes may be subject to drinking water application restrictions in some countries; check the application status before use and sale.
