Print on plain white paper - Part # 122919 INSTALLATION INSTRUCTIONS for the PILOT OPERATED KINK VALVE RETRO-FIT KIT PN 152839 & PN 152846 I. DESCRIPTION This kit is used to replace the counter balance arm actuated Kink Valve with the pilot air operated Kink Valve on the International delivery instrument head. The procedure outlines the removal and replacement of a single Kink Valve and syringe control. Typically three or more Kink Valve will be involved and this procedure should be performed on all Kink Valves simultaneously. II. INSTALLATION PROCEDURE 1. Remove the whip by loosening the whip set screw on the underside of the whip and pulling the whip off (See Figure 1). 12. Mount the new Kink Valve assembly on top of the Actuator assembly, using the small socket head screw. 2. Remove the instrument head cover by taking off the four phillips head screw on top of the instrument head. 13. Connect the handpiece tubing to the new Kink Valve barbed fittings in the same positions as before. 3. Turn off the master air supply. NOTE: Make a note of the tubing locations as you disconnect them from the Kink Valve. You will connect the tubing to the same locations on the new Kink Valve. 4. Remove the springs and disconnect the handpiece tubing from the Kink Valve by pulling them off of the barb fittings. 5. Disconnect the supply tubing (Blue, Clear and Orange tubing) from the Kink Valve by cutting them as close to the barbed fitting as possible. 6. Loosen the upper set screw in the hub block and slide the hub pin out and discard the actuator linkage. 7. Replace the hub pin and hub and tighten the set screw. 8. Remove the old Kink Valve by removing the slot head screw. 9. Attach the new pilot valve block using the same hole where the Kink Valve was attached and fasten with the large socket head screw (See Figure 2). 10. Position the actuator arm to rest on the large pin in the hub. 11. Attach one end of the new spring to the long screw on top of the pilot valve block and the other end to the large pin on the hub.

Extra tubing for this purpose is provided in the kit. 14. Connect the supply tubing to the same positions as before. 15. Repeat this procedure with the remaining Kink Valves. 16. Attach the top red tube from the actuator assembly to the fitting on the front of the kink Valve assembly. 17 Connect the bottom red tube in series (daisy chain) with the other red tubes on the adjacent Kink Valves. 18. Splice into the red 1/8" line in the instrument head. 19. Attach the syringe spring block to the plate in the instrument head using the small socket head screw. 20 Attach one end of the new spring to the long screw on top of the syringe spring block and the other end to the large pin on the hub. 21. Secure the syringe hose to the clamp on top of the syringe spring block. 22. Replace the whips and instrument head cover. TPW1536 Rev. B (11/99)
