Soda Lime
The soda lime should last for 8 to 24 hours of operation under most circumstances. Actual operating
time will depend upon ambient CO
2
levels. The soda lime supplied is an indicating variety: it will
turn slightly blue as it becomes exhausted.
The output of the CI-301AD may become unstable and show an increase in the CO
2
level as the soda
lime reaches exhaustion. When this happens, replace the soda lime.
