General Information:

• Avoid any abrupt pressure variations during start-up, operation, shutdown, cleaning or other sequences to prevent possible membrane damage. The maximum pressure change allowable is 0.5 bar/s.
• For assembly, refer to the latest version of the DuPont™ Inge™ Submerged Multibore™ Rack Assembly Manual (Form No. 45-D04906-en).
• If operating limits and guidelines in this bulletin are not strictly followed, any warranty will be null and void.
• To control biological growth during extended system shutdowns, a storage solution must be introduced into the membrane modules. For detailed information, see the DuPont™ Inge™ PES-UF Module Preservation Instruction (Form No. 45-D02946-en).
• Certified drinking water modules require specific conditioning procedures prior to producing potable water. For operating parameters, refer to the DuPont™ Inge™ Process and Design Manual for Submerged Modules (Form No. 45-D04909-en).
• Drinking water modules may be subjected to additional regulatory restrictions in some countries. Check local regulatory guidelines and application status before use.
• Flushing needs to be done according to the DuPont™ Inge™ PES-UF Module Rinsing Procedure (Form No. 45-D02947-en).
