5.2 Dryers
Under normal conditions Perma Pure dryers require little maintenance and can last for several
years. However, if there is no pre-filter and tubing becomes clogged or saturated with water, dryer
may require cleaning or repair. When disassembling the dryer, note that end fittings on the PD-
SERIES dryer can be easily rotated on shell tube. This rotation should be avoided to prevent
twisting membrane tubes inside the shell.
Dryer Element Replacement:
1. Take dryer assembly out of unit by unscrewing 4 screws on heater block, 4 screws on
bottom of unit along with 2 allen hex head screws.
2. Loosen all compression fittings connecting to dryer.
3. Refer to Appendix B for Dryer Element Replacement.
When connecting any fittings to purge ports of dryer, be sure not to tighten threaded fittings
more than 5 turns. Additional turns may cause fitting to damage element header just below.
