Check that the label on the new sensor is the correct gastype.2. Unscrew the weatherproof cover, loosen the retainer lockingscrew with the supplied hex key and unscrew the sensorretainer.3. Plug in the new sensor taking care to align the sensor pins withthe connector.4. Refit the sensor retainer, tighten the locking screw with thesupplied hex key and refit the weatherproof cover.5. Countdown time of up to 180 seconds (dependent on sensortype) is displayed.6. Acknowledgement of the gas type will be required beforeproceeding. For more information on setting gas type, seeGas Selection.7. After the sensor is installed and the gas type is confirmed,the Range, alarm levels and other important settings mustbe set; see Section 2.5 - Configuring the XNX UniversalTransmitter.8. Once the XNX has been configured, calibrate the detectorfollowing the procedures in Section 3 - Calibration.Section 2 - Installation and Operation 2-132.2 Wiring the XNX
