WARNING: If the detector installation is explosion proof, do not remove the detector
housing cap or junction box cover while the circuits are energized unless the
area is determined to be non-hazardous. Keep the detector housing cap and
junction box cover tightly closed during operation.
CAUTION: If you suspect the presence of CO in the monitoring environment, use the
calibration kit and a zero air calibration cylinder to introduce “fresh air” to the
CO detector and verify an accurate zero setting. See “Calibration” on page 17
for instructions to introduce zero air to the CO detector.
