General guidelines and notices

• 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 and 10% propylene glycol solution.
• Permeate obtained from the first hour of operation should be discarded.
• Avoid static permeate-side backpressure at all times.
• These membranes may be subject to drinking water application restrictions in some countries; users should check the application status before use and sale.
• For element loading, use only glycerine to lubricate o-rings and brine seal.
• The customer is fully responsible for the effects of incompatible chemicals on elements. The presence of free chlorine and other oxidizing agents will cause membrane failure, and the damage is not covered under warranty.
