2.5 Installing Pump Exhaust Line
This section describes exhaust connections and
installation. The Vertex System is equipped with
a vacuum pump that is located in the bottom of
the Vertex System cabinet. The pump exhaust line
connects to the manufacturing facility central toxic
exhaust system.
2.5.1 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.
2.5.2 Exhaust Line Connection
The instrument includes 20 ft. (6 m) of 3/8 in.
(10 mm) I.D. x 1/2 in. (13 mm) O.D. Teflon tubing.
Insert the tubing into the exhaust port on the top
of the unit to the depth of 0.9 in. (23 mm).
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 polypropolene tube with outside
diameter 0.375 in. (9.525mm) +/-.005 in.
(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 0.062 inches (1.5 mm) from its end.
