Exhaust Line Connection - Honeywell Vertex M User Manual

3.5.2 Exhaust Line Connection

The monitor includes 20 ft. (6m) of 3/8 in. (10 mm) I.D. x 1/2 in. (13 mm) O.D. tubing. Insert the
tubing into the exhaust port on the top of the unit to the depth of 0.9 in. (23 mm).
Leaks in the exhaust tubing connection can cause exposure to toxic gases from
remote sample areas.
To ensure a leak-free installation:
1. Use a polypropylene tube with outside diameter 0.375 in. (9.525mm) +/-.005 in.
(0.127mm).
2. Verify that the external surface of the tube is free of score marks and scratches that could
compromise the O-ring seal used in the fitting over the insertion depth.
3. Cut the tube end perpendicular to its length 0.062 inches (1.5 mm) from its end.
4. Insert the tube in the fitting to a depth of 0.95 in. (24.13mm) ±0.05 inches (1.27mm)
With the system running, verify the leak integrity with a small amount of leak test fluid.
