Figure 66 Align Recoat Mold
11.5.3. Flush Recoat System
The recoat pumping system should be flushed clean every 6 months as part of the recoat material replacement
procedure. Before flushing the system, make sure to have lens tissue and cleaning solution (acetone or alcohol)
available prior to proceeding. To flush the system follow the instructions below and see Figure 67:
1. Raise the mold top.
2. Position the selection lever to the inject position (lever horizontal).
3. Screw in (turn clockwise) the knurled syringe screw until a slight resistance is felt at the end of travel. Do
not use excessive force when turning the screw once the end of travel is reached. The end of travel point
is reached when the leading edge of the syringe screw is approximately level with the step in the syringe
body.
Note: Make sure to collect the recoat material as it comes out of the mold injection port. Do not allow
recoat material to run down the face of the mold and under the mold plate.
4. Replace the recoat bottle with one containing clean solvent.
5. Turn the selection lever to the fill position (lever down).
6. Unscrew (turn counter-clockwise) the knurled syringe screw. Continue unscrewing the syringe screw
approximately 3/4" or until it is felt to spin freely.
a. Note: Do not pull on the syringe screw once the end of travel is reached; this will pull the plunger
out from the syringe body.
7. Turn the selection lever to the inject position (lever horizontal) and screw in (turn clockwise) the syringe
screw until the inject end of travel point is reached.
a. Note: If the syringe screw was fully unscrewed until it spun freely, a slight forward pressure may
initially be required to re-catch the threads.
8. Watch the injection port for signs of solvent.
a. Note: Make sure to collect the solvent as it comes out of the mold injection port. Do not allow
solvent to run down the face of the mold and under the mold plate.
9. The above steps of filling and injecting the syringe must be repeated several times to fully displace recoat
material from the system. Repeat until clean solvent flows from the injection port.
10. Clean the mold plates of all excess solvent and recoat material.
11. Remove the bottle containing the solvent and dispose the solvent according to proper handling
guidelines.
12. Repeat steps 5 – 7 with no bottle present to purge any solvent from the injection system.
13. Prime the recoat system.
