Installation Step 3: Installing Sample Lines
Use only FEP Teflon® tubing to assure proper sample transport. Other types of tubing are not
sufficiently inert. See Specifications, for tube specifications. FEP tubing can be ordered from
Honeywell Analytics.
Install sample lines from each location to the top of the Vertex Edge System. This procedure

Honeywell Analytics supplies FEP grade Teflon tubing with all new monitors. This tubing is
manufactured to our own strict specifications and has been purged of all byproducts of the
manufacturing process. On occasions, users have supplied their own FEP type tubing. Should
you choose to use your own tubing, be advised that some brands of FEP tubing off-gas small
amounts of HF, which can be detected on start up by Honeywell Analytics monitors configured
for detecting mineral acids gases (HBr, HCl, HF, NF3). Before enabling building alarm systems,
make certain that 1) you have installed the correct Chemcassette, and 2) your monitor reads
zero.

Sample Line Installation Requirements
Follow the general requirements listed below when installing sample lines.
• Sample lines should not exceed 400 ft. (122m) in length.
• Route all lines as direct as possible to improve transport time.
• Avoid running sample lines through areas of great temperature extremes, such as adjacent to
steam or chiller lines.
• Sample lines should not be crimped, bent to less than a 12 in. (30.5 cm) radius, or placed in an
area where weight could collapse the tubing. Sample lines should be easily accessible for
periodic inspection.
• Where possible, leave as many bends exposed for periodic visual inspection of the line for
kinked or damaged tubing.
• Check each sample line installation for seal integrity after completing installation of the Vertex
Edge System. See Leak Checking Sample Lines, for the leak check procedure. Also use this
procedure to detect leaking or severed tubing after events, such as construction, which may
have affected the integrity of the tubing.
• Analyzers with unused points require a filter. Filter kit 1295A0702 is recommended.
• If an analyzer is installed in the Vertex Edge with a Chemcassette tape, the optics may need
cleaning before activating a previously unused point(s).
• Unused analyzer slots should have a plug installed for each point. These are included during
shipment
