Vertex M
24-Point Continuous Monitor
TM
2.5.1 Exhaust Line Installation Require-
ments
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 monitor includes 20 ft. (6m) 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).
System Exhaust
0.5 in (12.7mm) tubing
CAUTION
Leaks in the exhaust tubing connection can cause
exposure to toxic gases from remote sample areas.
Section 2 - Installation
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.
•
Insert the tube in the fitting to a depth of 0.95
in. (24.13mm) ±0.05 inches (1.27mm)
With the system running, verifty the leak integrity with
a small amount of leak test fluid.
2.6 Electrical Power
The Vertex M System requires a connection to a
source of electrical power. An easily accessible service
disconnect/power switch must be installed near the
instrument, and the switch must be marked as the main
disconnect for the Vertex M unit. The following warning
must be displayed at the switch:
WARNING
Hazardous voltages may exist at the Alarm
Contacts in this unit with the power switch
turned off. Ensure power is disconnected at
the source prior to servicing alarm contacts.
