DESCRIPTION
These instructions explain the proper procedures for installing and testing
nVent RAYCHEM TraceTek TT500X-HS sensing cables. (TT500X-HS refers
to either TT5000-HS or TT5001-HS). TT500X-HS sensing cables are primarily
intended for use in underground (fuel or solvent) pipeline applications. TT500X-
HS sensing cables ignore water but will detect and locate (fuel or solvent) spills
and leaks. (See the data sheet for specific performance characteristics.)
Important Notes
When used to monitor underground fuel pipelines, TT500X-HS sensing cables
are typically installed within slotted conduit that is routed alongside the main
pipeline. TT500X-HS sensing cable is designed for use within slotted PVC
conduit and is constructed with an outer layer of polyethylene fibers to provide
extra pulling strength and low friction during the installation process. The
sensor cable core is standard TT5000 (for fuel) or TT5001 (for solvent) with
well documented response times, numerous third party qualifications and years
of successful applications.
• TT5000-HS sensing cable is identified by the all white color of the outer jacket.
• TT5001-HS sensing cable is identified by a purple TRACER in the white
outer jacket.

Installation Instructions
TT5000-HS
(for fuel leaks)
TT5001-HS
(for solvent leaks)
DO:
• Store the cable in its original container in a clean, dry area until ready to install.
• Schedule the sensor cable installation as late as possible in the construction
schedule to avoid risk of damage or contamination by other contractors or
construction tasks.
• Remove cable from the pipe if any thread cutting, welding, soldering or similar pipe
fitting work will be performed.
DON’T:
• Drag the cable through water, paint, solvents, oil or other contaminants.
• Install damaged or contaminated sensing cable.
• Exceed the maximum pulling force of 100 kg (220 lb).
• Use the cable as a rope for lifting or securing any object.
• Allow tools or heavy objects to fall on cable.
• Exceed 3300 ft (1000 m) of individual sensor cable circuit length when using a SIM
alarm module.
• Test the cable with fuel. • Use tie wrap or wire to secure the cable.
