CAUTION: Make sure that there are NO contaminants between the O-ring and the sensor.
Contaminants that are present under the O-ring may cause the O-ring to leak.
5. Be sure the probe module sensor port is free of moisture and then insert the sensor into the correct
port. Gently rotate the sensor until the two connectors align.
6. With connectors aligned, screw down the sensor nut by hand, and then tighten using the sensor
installation tool.
