Assembling Refill Mechanism

2. Heat a solder iron to 450ºF.

3.Secure the syringe attachment in the upside down position so that it remains stable while the heat set insert is pressed into it.

4. Hold a 4-40, 0.135” heat set insert with a pair of needle nose pliers. Insert the solder iron into the heat set insert. Hold in this position for a few seconds to allow the heat set insert to heat up.

5. Lower the heat set insert into the hole. The pliers can be used to guide it into the hole, then repositioned to apply force to push it into the hold. Make sure the solder iron doesn’t slip through the insert or filament may melt into the heat set insert and prevent a screw from screwing in properly.

6. Repeat this process for both holes on the bottom of the syringe-stopcock holder.

7. Put the syringe in the Syringe Servo Attachment but don’t secure it with screws through the top holes yet.

8. Put the stopcock in the Servo Stopcock Attachment on the side with matching geometry.

9. Screw the syringe into the stopcock.

10. Connect the servo motor as detailed in the Electronics Connection Instructions. Turn on the motor and let it calibrate itself. Continue with the process once the servo motor has calibrated itself as it will now be in its zero position.

11. Attach the dual point servo horn to the servo motor.

12. Attach the Servo Stopcock Attachment to the servo. Push the Syringe Servo Attachment forward so that it is fully in contact with the servo motor.

13. Screw syringe holder into the sevo motor using 4-40 ⅜” screws

14. Secure a syringe in the holder by inserting two 4-40 ¾” screws and nuts through the upper holes.

16. Assemble the ¼-28 Fem to Fem Luer Tefzel and 1/16 Peek Nut, SF Short with the 1/16” tubing. Attach to valve on the stopcock which is parallel with the syringe. Refer to the Connecting the Tubing page.

17. Attach tubing to the valve of the stopcock which is 90 deg from the syringe. Refer to the Connecting the Tubing Page.
