Notices and Guidelines

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