General information

• Permeate flow for individual element may vary +25 or -15 percent.
• Element is vacuum sealed in a polyethylene bag containing less than 1.0% sodium meta-bisulfite and 10% propylene glycol solution.
• Element is supplied with interconnector.
• The presence of free chlorine and other oxidizing agents will cause membrane failure, which is not covered under warranty.
• 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; please check the application status before use and sale.
• For element loading use only glycerine to lubricate o-rings and brine seal.
