Installation and Operation Guidelines

• Discard permeate obtained from the first hour of operation.
• Avoid static permeate-side backpressure at all times.
• For element loading, use only glycerine to lubricate o-rings and brine seal.
• Minimum permeate flow for individual elements is 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.
• The presence of free chlorine and other oxidizing agents will cause membrane failure, and the damage is not covered under warranty.
