condensation caused by temperature fluctuations.
Water condensation in the sample lines could cause
false alarms.
Note:
Variables such as airflow, the molecular weight and
temperature of the sample gas, and the physical
conditions of the areas being monitored influence
the placement of the sampling locations. You may
need to consult your company's industrial hygien-
ist or safety officer before installing sample lines to
determine your company's policy related to sampling
locations and monitoring of the desired sample gas.

2.3 Optional Floor Mounting
For added protection with optional floor mounts, prepare
floor anchors to secure the base of the cabinet and
prevent tipping. See
Appendix A Installation Drawings
for floor mounting instructions.
2.4 Installing Sample Lines/Filters
Use only FEP Teflon
sample transport. Other types of tubing are not
sufficiently inert. See
tube specifications. FEP tubing can be ordered from
Honeywell Analytics. This tubing is manufactured to
our own strict specifications, and has been purged
of all by-products of the manufacturing process. On
occasion, 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
monitors configured for detecting mineral acids gases
(HBr, HCl, HF, NF
). Before enabling building alarm

2.4.1 Sample Line Installation Requirements
Follow the general requirements listed below when
installing sample lines.
•
Sample lines should not exceed 400 ft. (122 m)
in length.
•
Route all lines as direct as possible to improve
transport time. See
for transport times.
•
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
for
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 M System. See
Checking Sample Lines
procedure. Also use this procedure to detect
leaking or severed tubing after events, such
as construction, which may have affected the
