3.2 Connecting Gas-Sample & Exhaust Lines
3.2.1 Overview
A single gas-sample line needs to be run from the N
2
O Monitor to the area to be monitored. If desired, an
optional exhaust line can be installed to vent N
2
O gas away from the monitor.
3.2.2 Connecting the Gas-Sample Line
To connect the gas-sample line to the monitor, simply push the tubing onto the elbow connector and attach
the elbow onto the Gas Sample Port on the front of the monitor as shown in the illustration below.
The gas-sample line can be up to
50 ft (15.2 m)
in length. All tubing bends should have a radius of no less
than 5" to insure proper airflow. If kinks or obstructions occur in the line the monitor may not function
properly.
The end of this line should be placed near the potential leak source and positioned to reduce the possibility
of mists, aerosols, oil, water, dust, or other contaminates being drawn into the monitor.
An external filter (P/N 3015-5324) should be attached to the end of this line. See figure below.
