3.4 Initial Startup

Once installation of the gas detector has been completed, it is ready for startup. The following

procedures should be performed before putting the instrument into operation:

1.

Check the integrity of all wiring.

2.

Apply 24 VDC power.

The instrument should now be powered up. Upon power up, the

CO

2

monitor LCD displays the

PureAire logo and then displays CO

2

on the top line and the actual PPM reading on the bottom line.

The monitor will also output the proper mA signal to remote devices..

NOTE:

Ambient outdoor carbon dioxide levels are approximately 400ppm

CO2

405PPM
