9.
When the lamination is complete, remove resin from the valve plug face with a sander or cast saw.
10.
Remove clay from the hole, and then remove the screw and washer. The socket may be blown off with compressed air
through the hole.
11.
Unscrew the plug from the valve housing and discard.
12.
Remove excess resin from the outer face of the valve housing if required.
Final Assembly:
1.
Assemble the valve insert (Auto-expulsion version or Green Dot version) by gently hand tightening clockwise until the o-ring
on the outside of the valve insert makes contact with the sealing surface inside the valve housing.
Note: To prevent cross-threading, it is sometimes necessary to initially turn the insert counter-clockwise until the
threads are aligned properly, and then tighten clockwise.
2.
A valve key is provided to assist removal of the valve insert for individuals with limited hand strength or dexterity.
Disassembly and cleaning valve inserts:
Foreign debris such as dust, baby powder, and residue from lotions used for donning the
socket can become lodged in the sealing surfaces of the valve overtime and may cause a
decrease in vacuum performance.
Instruct patients to periodically wipe clean the outer o-ring and threads of the valve insert and
the inner threads and sealing surface of the valve housing. Use water or isopropyl alcohol.
To disassemble the valve insert for more thorough cleaning, steps 1-4 pertain to both the
Auto-expulsion and the Green Dot valve inserts:
1.
Remove the valve insert from the housing.
2.
Firmly press down on the valve button until the valve cover
snaps off.
3.
Maintain downward force of the button, while carefully
removing the inner o-ring.
This is made easier by using a small nut or other
object on a flat, sturdy work surface.
Press the assembly down onto the small object so
that the valve button lifts up from the inner seal
surface.
While the valve button is lifted, use a pick to
CAREFULLY remove the o-ring from the button. DO
NOT CUT OR DAMAGE THE O-RING!
4.
Remove the button and spring from the valve body. Clean
components with water and mild detergent, or isopropyl
alcohol. Ensure all sealing surfaces are free of debris or
residue.
