Additional Information

• Minimum permeate flow for individual elements: 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.
• 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; this damage is not covered under warranty.
