Complete Assembly Instructions
The jacketed process reactor, the fully assembled reactor head, stirrer shaft & agitators, stirrer shaft coupling, flake
retaining cup, PTFE stirrer bearing, temperature probe & adapter, S.S. inlet/outlet adapters, motor and motor mount arm
are shipped assembled on the support frame. (All joints must be properly greased to avoid “freezing”and improve
vacuum. PTFE sleeves and keck clips are available separately.) Use the following instructions should you need to remove
or adjust these components.
1. Attach the zero dead space drain valve (CG-1968-Q) to the reaction vessel via the 2”beaded pipe coupling (CG-
1968). Tighten the coupling to the specified torque setting.
2. Attach the S.S. beaded pipe adapters (CG-1969-A) to the inlet/outlet of the reaction vessel via the 1”beaded pipe
coupling (CG-1968). Tighten the coupling to specified torque setting. PLEASE NOTE: IF YOU ELECT TO USE
THE CG-1969-M HIGH FLOW MANIFOLD SYSTEM, THIS NEXT STEP CAN BE SKIPPED.
3. Carefully lower the reaction vessel into the support frame and rest the bottom of flange on the red silicone tubing.
Slide front reaction vessel plate tight against the reactor and tighten the plate via the four Allen screws (Figure A).
4. Place the PTFE envelope gasket on the flange of the reaction vessel.
5. Assemble the stirrer shaft, agitators, and PTFE flake retaining cup, and lower into the reaction vessel.
6. While lowering the reaction vessel lid onto the vessel, carefully insert the end of the stirrer shaft through the center
neck of the lid. PLEASE NOTE: THE PTFE STIRRER BEARING IS NOT INSERTED AT THIS TIME.
7. Dismantle then slide the PTFE stirrer bearing over the end of the stirrer shaft and “press”into the center neck,
sealing the o-ring.
8. Position the powder fill port towards the front of the reactor.
9. Secure the vessel and lid together with the clamp ring, making sure the entire PTFE envelope gasket is seated
evenly on the flange. Tighten the wing nuts in a star pattern (Figure B). Work your way around the entire clamp until
you have repeated this 3-4 times and all the wing buts are tight. DO NOT OVER TIGHTEN.
10. Attach the universal stirrer shaft coupling to the 1/4 HP electric stirrer motor shaft. Then attach the motor to the
support frame via the supplied four socket head cap screws.
11. Insert the end of the stirrer shaft into the coupling and tighten the collar with an Allen wrench. Check the vertical
alignment of the reactor and adjust if necessary.
12. Tighten the black compression nut on the PTFE stirrer bearing, which compresses the bearing onto the stirring
shaft.
13. Attach the electric stirrer motor controller and the digital temperature monitor to the support frame via the large
Kwik Klamp II and 1/2" OD 90°support rod.
14. Attach the control cord from the electric stirrer motor to the rear panel of the controller. Make sure the speed
control knob on the controller is turned completely off BEFORE turning the controller on. If using the air motor,
attach the air source to the motor. The brass needle valve on the back of the air motor should be CLOSED.
15. Loosen the compression nut then insert the thermocouple through the thermocouple adapter and the insert the
adapter into the desired side neck. Adjust the depth of the thermocouple by tightening the Chem-Thread at the top
of the adapter. PLEASE NOTE: CHECK TO SEE THAT THE THERMOCOUPLE DOES NOT COME INTO
CONTACT WITH EITHER AGITATOR BY MANUALLY TURNING THE STIRRER SHAFT. Attach the
thermocouple cord to the probe then to the temperature monitor.
16. Attach condensers and any other peripheral glassware.
