Connecting the Gas
-
Sample
Probe
To connect the gas-sample probe to the monitor, simply push the elbow connector into 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 ensure proper airflow. If kinks or obstructions occur in the line the monitor may not function properly.
When searching for leaks, the end of the probe 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.
2.2.2
Connecting the Exhaust Line
(Optional)
The exhaust line carries the exhausted gas sample away from the monitor, and should be installed if the monitor is
located in a confined, poorly ventilated area.
The exhaust line can be up to
50 ft (15.2 m)
in length. Ideally this line should terminate outdoors in a location that
is not exposed to the elements.
2.2.3
Using the Push
-to-
Connect (PTC) Fittings
Connect the exhaust line to the monitor by firmly pushing the tubing into the Exhaust Port’s push-to-connect (PTC)
fitting. See below. If the exhaust line terminates outside the building, position the tubing so that no water or
moisture can enter the line. Note that this line does not require a termination filter.
To connect the exhaust line to the exhaust
port’s PTC fitting, firmly push the
appropriate tubing into the hole in the
center of the connector until it seats in
the connector. Refer to the figures at the
left.
To remove tubing from a PTC connector,
push and hold the spring-loaded collar
inwards, then simultaneously withdraw
the tubing. Refer to the figures at the
right.
