green wire to terminal labelled LEL GRN, black wire to terminal labelled LEL
BLK.
• CO or H2S gas detector.
Red wire to terminal labeled TOXIC RED, black wire to terminal labelled TOXIC
XXX.
• Oxygen gas detector.
Green wire to terminal labelled OXY GRN, white wire to terminal labelled OXY
WHT.
CAUTION: Allow the replacement detector to warm up for 15 minutes before you continue with
the next step.
10. Re-install the control PCB (and ribbon cable if necessary). Be sure the ribbon cable is
routed down below the control PCB so it will not be damaged by the cover when it is
screwed back on.
11. Secure the junction box cover to the junction box.
12. Calibrate the replacement detector as described in the Calibration section of this
manual.
Replacing the CO and H2S Sensors
1. Turn off or disconnect power at the power source end.
2. Unscrew the bottom section of the CO or H2S detector housing from the top section.
3. Unplug and remove the sensor.
NOTE: The CO sensor has a charcoal disk filter held onto it by a rubber retaining boot.
When replacing a CO sensor, remove this filter and boot from the old sensor. RKI
instruments recommends replacing the charcoal disk filter whenever a CO
sensor is replaced. Re-install the charcoal disk filter and retaining boot before
continuing.
4. Carefully match the replacement sensor’s male pins with the 4-socket pattern in the
top section and plug it in.
5. Screw the bottom section of the detector housing into the top section.
6. Secure the junction box cover to the junction box.
7. Turn on power at the power source end.
8. Calibrate the detector as described in the Calibration section of this manual.
Replacing the CO Sensor Charcoal Filter
1. Turn off or disconnect power at the power source end.
2. Unscrew the bottom section of the CO or H2S detector housing from the top section.
3. Remove the rubber retaining boot with the charcoal filter disk from the sensor.
4. Replace the charcoal filter disk in the rubber retaining boot and install the boot onto
the sensor.
5. Screw the bottom section of the detector housing into the top section.
6. Turn on power at the power source end.
