TT3000 and TT5000 Series
Bulk Sensing Cable Installation Instructions
GENERAL NOTES—DO'S AND DON'TS
• Store the sensing cable in its original container in a clean, dry area prior
to installation.
• Schedule sensing cable installation after pipe is assembled and pressure
tested.
• Install alarm module first, then install sensing cable from the module
outward.
• Clean the area where the cable will be installed, to remove debris and
sources of contamination.
• Install sensing cable before burying pipe.
• Provide "as built" drawings to facilitate completion of a system map.
• Replace TT5000 sensing cable once it has contacted a solvent or fuel.

GENERAL INFORMATION
These instructions detail techniques used to install nVent RAYCHEM
TraceTek TT3000 or TT5000 bulk sensing cable into double-containment
pipe. Installation is made from pull point (access tee) to pull point. Two
people, the feeder and the puller, are needed to complete the installation.
They must be able to communicate at all times during the installation.
Two-way radios may be required. These instructions assume that 1/4-
inch or 3/8-inch hollow braid pull rope has been installed according
to the TraceTek Double Containment Installation Guide (LIT-138). To
ensure that the pipe is cable ready, see the TraceTek Products Selection
Guide (H54783), Section 2. After the cable has been installed, use the
connector installation instructions included in connector kits for nVent
RAYCHEM TraceTek TT3000 and TT5000 sensing cables (TT-3000-CK-
MC-xxx or TT-5000-CK-MC-xxx). For more information call (650) 216-
1526.
TOOLS AND MATERIALS NEEDED
• Ohmmeter (20 MΩ range or greater)
• Kellems grip (TT-KELLEM-GRIP)
• Reel mounting stand (to allow reel to spin and pay off sensing cable;
see page 4)
• Two lengths of 3/4-inch electrical conduit bent to a gentle sweep.
These must be longer than the highest riser (the vertical pipe section
at access tees), flared slightly, and deburred at both ends (see Step 4
on page 4).
• Electrical tape
IN ADDITION, FOR INSTALLING TT5000 SERIES
SENSING CABLES:
• TT-ULTRATORCH flameless heating tool or appropriate heat gun
• Pliers (to crimp heat-shrinkable tubing)
• Masking tape
• Drag the cable through contaminants (such as pipe dope, PVC cement,
alcohol, 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 cables.
• Drop tools, or sharp or heavy objects onto the cable.
• Pull sensing cable with excessive force (more than 50 pounds /20 kg for
TT5000, more than 75 pounds/30 kg for TT3000).
• Pull bulk TT5000 sensing cable without sealing its end.
• Place TT5000 sensing cable where it is subject to pinching or
temperatures above 60°C (140°F).
• Leave TT5000 sensing cable installed under tension.
• Use adhesive tapes or clamping devices to permanently secure the
sensing cable.
• Allow cable ends to become wet, dirty, or contaminated.
