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 14 for instructions to introduce zero
air to the CO detector.
