GENERAL INFORMATION
These instructions explain the proper procedures for installing and testing nVent
RAYCHEM TraceTek TT3000 and TT5000 series modular and zone sensing
cables, and provide specifics for sumps, subflooring, and containment trenches.
For double-containment pipe applications, refer first to the TraceTek
Double-Containment Installation Guide (LIT-138); for double-wall tank
applications, refer first to the General Instructions for TraceTek Installation in
Double-Wall Tanks (H55313).
The General Installation Instructions for TraceTek Environmental Applications
(H55523) provides an overview of the installation process for the TraceTek system,
and refers to detailed instructions for each step.
To obtain copies of installation instructions, consult nVent at (650) 216-1526.
TOOLS AND MATERIALS FOR INSTALLATION AND TESTING
• TT-PTB-1000 Portable Test Box with adapters or ohmmeter
(20-MW range or greater)
• TT-ULTRATORCH flameless heating tool or appropriate heat gun.
• TT-MLC-MC Modular Leader Cable (needed for testing with ohmmeter)
• TT-MET-MC Modular End Terminations (not needed for zone cables)
ADDITIONAL MATERIALS FOR SUMP, CONTAINMENT TRENCH,
OR SUBFLOOR APPLICATIONS:
• For TT3000 sensing cable: TT-HDC-1/4 or TT-HDC-1/4-200-NA
Hold-Down Clips
• For TT5000 series sensing cables:
TT-HDC-1/2-NA-50 hold-down clips
• 3M-type 1300 or 08001 adhesive (obtained locally) for hold-down clips
with no adhesive (not required for TT-HDC-1/4)
General Notes—Do’s and Don’ts
COMPLETE BILL OF MATERIALS
Before beginning installation, confirm there is a plan
for the leak detection system layout, and a complete
bill of materials. In addition to sensing cables, the leak
detection bill of materials should include a TraceTek
alarm module, leader and/or jumper cables, mapping
(TT-TAG), and various other components, such as
Modular Branching Connectors, (TT-MBC-MC).
TT3000 and TT5000 Series
Modular Sensing Cables Installation Instructions
Do
• Store the sensing cable in its original container in
a clean, dry area prior to installation.
• Schedule sensing cable installation after major
construction work (which could damage or
contaminate the cable) has been completed.
• Clean the area where sensing cable is to be
installed and remove any debris or other source
of contamination.
• Replace TT5000 series hydrocarbon sensing
cable once it has contacted a solvent or fuel.
Don’t
• Drag sensing cable through contaminants (such as pipe dope, PVC cement, solvents, oil, dirt).
• Use damaged or contaminated sensing cable.
• Solder or weld near the cable without protecting it from heat, flux, and splatter.
• Use pulling lubricants to install TraceTek sensing cables.
• Drop tools or sharp or heavy objects onto the cable.
• Pull the sensing cable with excessive force (more than 50 pounds/20 kg).
• Place TT5000 series sensing cable where it is subject to pinching or pressure, as this will trigger
an alarm.
• Subject TT5000 series sensing cable to temperatures higher than 80°C (176°F).
• Use adhesive tapes or clamping devices to secure the sensing cable.
• Allow cable connectors to become wet, dirty, or contaminated.
