Notices and guidelines
- Minimum permeate flow for individual elements is 20 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 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, and such damage is not covered under warranty.
