and parallel to glass shell.
7. Carefully mate bottom assembly onto top piece. Slight twisting motion may be required
to allow shell to slip over o-ring seal.
8. Visually make sure element is seated correctly in top groove.
9. Replace bolt through hole in bottom piece and screw clockwise into top piece. Do not
over-tighten center bolt. It should be just tight enough so it does not vibrate loose.
Over-tightening will not help the filter to seal.

Dryers
Under normal conditions, Perma Pure dryers require little maintenance and can last for
several years. However, if there is no pre-filter and the tubing becomes clogged or
saturated with water, the dryer may require cleaning or repair. When disassembling the
dryer, note that the end fittings on the PD-SERIES dryer can be easily rotated on the shell
tube. This rotation should be avoided to prevent twisting the membrane tubes inside the
shell.
Refer to Appendix B for PD dryer element replacement.

Media Replacement: When deposits are visible on 75% of the scrubber, scrubbing media
needs to be replaced.
