Toxics Sensors
Replace the sensor when:
1. The detection circuit cannot be calibrated correctly.
2. The display does not show 00 immediately after the start-up
sequence and cannot be set to zero by the Demand Zero com-
mand.
Note
Allow up to 1/2 hour after the toxics sensors have been
replaced to show a normal response, then calibrate.
