Notes on Dimensions:
- For male elements, "C" is the outer diameter.
- Male elements have a protruding permeate tube.
- Dimension "D" is 30.5 mm (1.2 in) for modules from 2540 to 4021.
- For the 4040 module, dimension "D" is 26.7 mm (1.05 in).
Important Information
- Start-up: Flush elements for 30 minutes at low pressure and discard permeate prior to operation.
- Cleaning: Elements must be cleaned periodically to ensure proper operation and prevent membrane damage.
- Storage: Elements must be stored appropriately to ensure proper operation and prevent membrane damage.
