• Dimensions are shown in Inches (millimeter). (Specific overall dimensions are not clearly extracted from the provided text but diagrams are indicated in the original PDF).

Operating Information

• For recommended design range, it is advised to consult the latest technical bulletin, design guidelines, computer design program, or an application specialist.
• The Limited Warranty will be null and void if operating limits are not strictly followed.
• 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, flushing of elements with seawater for 30-60 minutes every two days is recommended.
• The presence of free chlorine and other oxidizing agents, especially with heavy metals acting as oxidation catalysts in feed water, can cause unexpected membrane oxidation. It is strongly recommended to remove these oxidizing agents from feed water before operating the RO system.
• Permeate from the first hour of operation shall be discarded.
• The customer is fully responsible for the effects of chemicals that are incompatible with the elements, and their use will void the Limited Warranty.
