• These membranes may be subject to drinking water application restrictions in some countries; check the application status before use and sale.
• For element loading, use only glycerine to lubricate o-rings and brine seal.
• Elements are dry and vacuum sealed in a polyethylene bag.
• The presence of free chlorine and other oxidizing agents will cause membrane failure, and the damage is not covered under warranty.
