• Select a site where the target gas is likely to be found first. NOTE: If your application does not require a specific mounting site, mount the detector at approximately breathing level. 4 • 65-2437RKSS-05 CO Detector... -
Page 9: Wiring The Co Detector To A Controller
Remove the junction box cover. WARNING: To maintain the explosion proof classification of the CO detector, a conduit seal must be used within 18 inches of the junction box conduit hub used for wiring to the controller. 65-2437RKSS-05 CO Detector • 5... - Page 10 Route the cable or wires leading from the CO detector through one of the conduit hubs at the controller housing. Use appropriate conduit fittings and construction technique for the environmental rating of the controller. RKI controllers are typically rated NEMA 4X.

Page 11: Startup
If using shielded cable, connect the cable’s drain wire to an available chassis ground at the controller. RKI controllers typically have a ground stud that is a convenient grounding location. 10. Reinstall the junction box cover. Start Up This section describes procedures to start up the CO detector and place the detector into normal operation. -
Page 12: Maintenance
This procedure describes a test to verify that the CO detector responds properly to carbon monoxide. It describes a test using a fixed flow regulator with an on/off knob. RKI Instruments, Inc. recommends using a 0.5 LPM (liters per minute) fixed flow regulator. -

Page 16: Calibration
It describes calibration using a calibration kit that includes a calibration cup, calibration gas, sample tubing, and a fixed flow regulator with an on/off knob. RKI Instruments, Inc. recommends using a 0.5 LPM (liters per minute) fixed flow regulator. - Page 17 NOTE: If you do not allow the gas reading to decrease below the alarm points, then unwanted alarms may occur. 10. Verify that the controller display reading decreases and stabilizes at 0 ppm CO. 11. Store the components of the calibration kit in a safe and convenient place. 65-2437RKSS-05 CO Detector • 13...
