Maintenance

3.Pull old thermocouple from probe body and discard.

4.The new thermocouple has been coiled for shipping purposes. Straighten the thermocouple using your thumb and index finger.

5.If not already done, install supplied O-Rings onto thermocouple.

6.Insert thermocouple into probe body until it “bottoms out.”

7.Strip 1/4 inch of insulation from each of the probe’s thermocouple

connector­ wires.

IMPORTANT: In Step 8, the thermocouple wires must first be twisted together and then crimped.

8.Twist both red thermocouple wires together; insert them into the sup- plied wire-splice connector; and then crimp the connector using a pair of pliers. Repeat this step for the yellow thermocouple wires.

9.Reassemble the probe handle, being careful not to pinch the thermo- couple wires between the handle pieces. In addition, ensure that the end of the thermocouple is in front of the rib molded into the bottom handle piece; otherwise, the handle pieces will not fit tightly together.
