Be sure to follow all codes and company procedures that pertain to
the maintenance, repair, testing, and calibration of all safety
equipment, including this detector
At a minimum, the detector must be tested after installation and at
least once a month in critical areas, once a quarter in non-critical
areas, thereafter, to ensure it is operating correctly. Also, the
detector must be calibrated at least once a year to ensure it is
detecting and displaying ammonia concentration accurately.
At the time of calibration, it is highly recommended to use ammonia
test gas that can be purchased from Cool Air Inc. or their
distributors.
