Installation Step 4: Installing the Pump Exhaust Line
This section describes exhaust connections and installation. The Vertex Edge is equipped with a
vacuum pump located at the bottom of the Vertex Edge cabinet. The pump exhaust line
connects to the manufacturing facility central toxic exhaust system.
Exhaust Line Installation Requirements
Follow the general requirements listed below when installing exhaust lines.
The length of the line should not exceed 50 ft. (15 m). If longer distances are required, contact
Honeywell Analytics.
Do not crimp exhaust lines or place them in an area where weight could collapse the tubing or
bend them to less than a 12 in. (30.5 cm) radius.
Where possible, leave as many bends exposed for periodic visual inspection of the line for kinked
or damaged tubing.
Varying exhaust pressure can induce pump failure or flow faults.
Exhaust Line Connection
The instrument includes 50 ft. (15 m) of 0.375in. (10mm) I.D. x 0.5in. (13 mm) O.D. Teflon or
Polypropylene tubing. Insert the tubing into the exhaust port on the top of the unit to the depth
of 0.9in. (23mm).
CAUTION
Leaks in the exhaust tubing connection can cause exposure to toxic gases from remote sample
areas.
To ensure a leak-free installation:
• Use a polypropylene tube with outside diameter 0.375in. (9.525mm) +/-.005in. (0.127mm).
• 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.
• Cut the tube end perpendicular to its length 0.062in (1.5mm) from its end.
• Insert the tube in the fitting to a depth of 0.95 in.(24.13mm) ±0.05in. (1.27mm)
With the system running, verify the leak integrity by plugging a sample point and monitor
sample point flow via HMI point flow screen.
