Operational 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.
- Free chlorine and other oxidizing agents will cause membrane failure, and such damage is not covered under warranty.
