General Guidelines and Notices

• 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; check application status before use and sale.
• For element loading, use only glycerine to lubricate O-rings and brine seal.
• Permeate flow for individual elements may vary +35% or -20%.
• Elements are vacuum sealed in a polyethylene bag containing less than 1.0% sodium meta-bisulfite.
• The customer is responsible for the effects of incompatible chemicals. Free chlorine and other oxidizing agents will cause membrane failure, and such damage is not covered under warranty.
