2.  Remove the cover from the Converter chassis. 
3.  Unscrew the (4) nuts that secure the front panel to the chassis.  They are located just 
behind the Front Panel along the top. 
4.  Lower the Front Panel to gain easier access to the end of the quartz tube. 
5.  Unscrew the (3) nuts that secure the inner cover protecting the Heater Block and 
quartz tube.  Remove this cover. 
6.  Cut the tie-wrap that secures the thermocouple to the fitting at the end of the quartz 
tube.   
7.  Loosen the Teflon fitting at the end of the quartz tube taking care not to put any 
stress on the tube, and slide the fitting off the tube. 
8.  Remove the thermocouple. 
9.  Disconnect the thermocouple wires from the Temperature Controller noting that the 
‘Yellow’ wire goes to pin 1 and the ‘Red’ wire goes to pin 2. 
10. The thermocouple should slide into the Heater Block. 
11. Replace the Tie-Wrap Hold-Down. 
12. Form the thermocouple wire so that it rests in the cavity with little movement. 
13. Connect the (2) wires of the thermocouple to the Temperature Controller.  The 
“yellow” wire should be connected to pin 1 and the “red” wire should be connected to 
pin 2. 
14. At this point, all connections have been made, both electrically and pneumatically.  A 
leak check should be performed on the Converter to verify that all connections are 
leak free.  If a leak is detected, the leak should be resolved before continuing. 
15. Install the inner cover of the Heater Block and secure with the (3) nuts.  Close the 
Front Panel and secure with the (4) nuts.  Install the top cover on the Converter 
chassis. 
16. The Converter is now ready for the application of power.  You will be looking for an 
indication from the Temperature Controller that it is functioning correctly and driving 
the heater to the desired “set” temperature.  Apply power now. 
17. After the Converter comes to the regulated temperature, perform the Auto Tune 
function to tune the Temperature Controller to the new thermocouple. 
18. After the Auto-Tune process is completed, verify that the “process” temperature is 
indicating that the desired temperature is stable and being regulated. 
The converter is now ready for operation.
