Connect gas and power lines:
Do not install the sensor until the gas lines have been connected and the electrical
connections made.
Install the unit, and connect the sample gas inlet and exhaust, power and appropriate
alarm and output connections. Connect the sample gas line to the fitting on the rear
panel using the ¼” compression fittings provided, and the exhaust line to a suitable vent.
Sample gas:
The sample gas inlet pressure should be between 1-40psig.
Span gas:
Span gas (if desired) must be provided by a user-supplied valve.
Exhaust:
The exhaust line may be left open, or vented to a suitable vent. If used with a scavenging
system, use a large diameter pipe (for example, ½” pipe) as the input to the scavenging
system, and allow the ¼” vent to terminate a little way inside this larger line without
sealing it. The scavenging system will then draw in room air along with the sample, while
leaving the exhaust at atmospheric pressure.
