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
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
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
The converter is now ready for operation.
