Operating Information
- For recommended design range, consult the latest technical bulletin, design guidelines, computer design program, or an application specialist.
- Operating limits must be strictly followed to maintain the Limited Warranty.
- Elements are wet tested, treated with tested feed water solution, and vacuum packed in oxygen barrier bags with deoxidant.
- To prevent biological growth during system shutdown, perform 30-60 minutes flushing with seawater once every two days.
- Permeate from the first hour of operation shall be discarded.
- Users are responsible for effects of incompatible chemicals; their use will void the Limited Warranty.
