Pulling the cable:
• TT500X-HS sensing cable is sensitive to pressure from
such things as pinches or tight corners. Cable stress,
binding and kinking can result in cable damage and
potential false leak detection signals. Take care during
installation to maintain cable integrity in order to promote
a successful project.
• Two people are needed to manage the pull rope. One per-
son is on each end of the end pull rope, and each person
must be able to communicate with the other in case of
problems during the pull.
• Before pulling the cable into the conduit, identify the
correct pull rope. If there is more than one section of pull
rope at this access point, the person feeding the cable can
lightly tug the pull rope, while the person on the pulling
end confirms they feel the tension.
(A common mistake results from the wrong rope end be-
ing pulled, and the other end of the pull rope disappearing
into the conduit).
Note: Be careful not to lose the rope into the access point
conduit.
It can be time consuming and expensive to recover a
pull rope lost into the conduit.
• Confirm the pull rope moves easily. Slow and steady
pulling is recommended to promote an easier installa-
tion which results in reduced stress on the cable. The
person feeding the cable into the conduit needs to provide
continual slack to reduce stress on the cable. The person
feeding the cable must be able to communicate problems
(such as snags or twisted cable) to the person pulling,
before the sensing cable is subjected to excessive stress.
• As you pull, coil the pull rope by hand and keep the
pull rope out of the dirt by placing it on cardboard or
plastic sheeting.
• If the pull rope becomes stuck, do not increase pull
force-instead pull the rope in opposite direction for a
short distance, then try repulling in original direction
with normal force.
• Finish the cable pull by extending the TT500X-HS-MC
(with factory installed connectors) or TT5000-HS-HYB-
HSE (with factory installed end termination) cable at least
1 foot beyond top of the access point conduit riser.
• For TT500X-HS (bulk sensing cable without connectors)
cable, extend at least 2 feet beyond top of the access
point conduit riser. The extra length is necessary due to
connectorization requirements.
• Secure excess pull rope by coiling around the riser pipe
and taping in place.
• Cover conduit ends to maintain cleanliness within conduit.
Use a plastic bag taped in place, or stuff a clean rag into
conduit end.
Expose the sealed end of the cable, see illustrations A,
B and C below
• For connectorized cable (TT500X-HS-MC), remove the
heat shrink tubing from the sealed end, then remove the
attached end termination to access the connectorized
cable end.
•
Test each length of connectorized sensing cable after
pulling into conduit and before attaching it to cable
already installed. Confirm that the sensing cable is clean
and intact by following the Sensing Cable Test Procedure,
described later in this document.
Connectorization procedure for bulk cable
• Bulk (unconnectorized) cable is usually connectorized
after pulling into conduit. Use connector kit TT5000–
HUV–CK–MC–M/F for TT500X-HS sensing cable. Refer
to TraceTek document H54830 for detailed instructions
regarding connectorization procedures. If bulk cable is
cut and connectors will not be immediately installed, use
shrink tubing or carefully tape the cable ends to protect
cable integrity (water/physical damage). If water enters
cable ends, the cable will be compromised and may have
to be replaced.
• Grasp rope braid about 1 in. (25 mm) behind the taped
end near the looped end of the pull rope. Feel for the
sealed end of the sensor cable beneath the rope braid.
Bend the rope braid to a 90 degree angle and locate
sealed end of the sensor cable.
• Spread the rope braid fibers apart to expose the sealed
end of the sensor cable.
