Mounting the CO

Transmitter
1. Select a mounting site that is representative of the monitoring environment. Consider
the following when you select the mounting site.
• Select a site where the transmitter is not likely to be bumped or disturbed. Make
sure there is sufficient room to perform start-up, maintenance, and calibration
procedures.
• Mount the transmitter at least six feet from the floor to minimize the possibility of
someone breathing on the unit. The exhaled CO
2
may cause an alarm.
