Some R.O. elements are packaged in sealed plastic bags with the protective chemical formaldehyde,
which is poisonous; avoid fumes and keep away from eyes and mouth. Handle with extreme care. After
handling, wash hands thoroughly with soap and water.
After removing R.O. element from sealed plastic bag, take care to keep element clean. Failure to do so
will bring dust and dirt into R.O. elements and cause early element failure.
Remove new R.O. element (4) from sealed plastic bag.
Refer now to fig. 3-6, and install brine seal (1) in groove of R.O. element (2) making sure open end faces
R.O. pump end of ROWPU or opposite end of the direction of flow.
