10. Replace the front cover of the monitor and ensure that the gasket is replaced as well to maintain CE approval
and NEMA 4 rating.
11. Tighten the four (4) screws to secure the front cover.
12. Connect the gas lines, vent line first, as previously described.
13. Proceed to calibration.
Procedure - Remote Oxygen Sensor:
1. Locate Item #1 sensor cable.
2. Loosen the knurled lock nut attached to the sensor cable and pull the attached female plug out of the male
connector attached to the sensor
3. Locate Item #6 sensor retaining nut.
4. Unscrew the retaining nut from the sensor and remove the sensor.
5. Discard the old sensor in accordance with local regulations for disposing of a battery.
6. Remove the oxygen sensor from the bag. Do not remove the shorting device (wire loop) from the sensor.
7. Position the threaded end of the sensor into the U-shaped opening of the sensor mounting bracket.
8. Screw Item #6 sensor retaining nut onto the threaded end of the oxygen sensor, finger tighten to secure.
9. Remove the shorting device (wire loop) from the receptacle located at the rear of the sensor. Minimize the time
the sensor is exposed to ambient air.
10. Assure the keyway registration of the female plug on the cable and male receptacle on the sensor match up.
11. Push the female plug (including the knurled lock nut) molded to the cable into the male receptacle attached to
the new sensor.
12. Screw the knurled lock nut attached the cable onto to the male connector attached to the sensor, tighten
finger tight plus ¼ turn..
13. Refer to the Calibration Gas Connections above and proceed to calibration.
