b. Element Installation
1. Always wear gloves when handling the element to prevent skin oils from
contaminating membrane surface.
2. Remove nut from tee fitting at the outlet end of the dryer.
3. Remove bend clips from dryer housing tube and straighten tube to allow
element to slip in easily.
4. Slip two new o-rings onto one end of the new element.
5. Install other end of the element into the filter side of the dryer housing by
gently pushing element into the housing. Be careful not to kink tubing. Allow
about ¼” to protrude from end of the tee fitting.
6. Install third o-ring seal around end of the element and gently push it into the
recess of the tee fitting.
7. Install union and hand tighten, followed by a ¼ turn with a 5/8" wrench.

9. Replace tube bend clips.
10. Install filter housing by holding filter heater sleeve from the inside of the
enclosure and lining up the union threads with the element and tee fitting end
of the dryer. Some flexing of the dryer heater sleeve may be necessary to
line up the threads. Do not cross thread the union! When the threads are
lined up properly, virtually no resistance will be felt until union
contacts the o-ring seal. Turn the filter housing until tight and the purge
port is visible through the hole in the heater sleeve.
11. Apply new Teflon tape to the tee fitting and thread it into the purge port. Do
not cross thread the port!
