6. First, loosen the capillary tube compression fitting until it slides freely on the capillary tube.
Second, loosen the frypot pass-through nut until it slides freely on the capillary tube. Remove
the capillary tube and bulb from the frypot.
7. Install the replacement thermostat capillary tube and bulb in the frypot. Apply a small amount of
Loctite PST567 compound or equivalent to the threads of the frypot pass-through nut and screw
the replacement thermostat securely into the frypot, being careful not to twist the capillary tube
as the fitting is tightened. DO NOT tighten the capillary tube compression nut at this time.
8. Position the thermostat bulb in tube-mounted clamp and replace mounting hardware. Ensure
probe bulb is properly positioned in the clamp (¼" from burner tube) and screws are properly
tightened.
9. Tighten the capillary tube compression nut once the capillary tube is properly positioned.
NOTE: Once the compression nut is tightened, the capillary tube cannot be repositioned. If a
mistake in installation has been made, a new thermostat will have to be installed.
10. Mount the thermostat control to the mounting bracket using the screws removed in Step 4.
11. Connect the wires disconnected in Step 3 to the thermostat.
