4. Install Cable Into Pipe
Ensure that plumbing fitting(s) at start of piping are installed as appropriate. Plumbing fitting(s) at start of
piping must be suitable to accept Compression Fitting Assembly (3/4" NPT).
Cable will slide easier through pipe if Petroleum Jelly or Wire Pulling Lubricant is applied to cable.
For Small pipes 3/4" to 2" diameter, see Configurations 1 and 2 under "Preparation for Installation of the
Cable", on page 4, to select cable configuration that best suits your application.
Note: The heating cable inside the pipe reduces the effective cross-sectional area of the pipe - this may
result in lower pressure/flow in high usage situations.
For Large pipes greater than 2" up to 6" diameter, see Configurations 3 to 6 under "Preparation for
Installation of the Cable", on pages 5 and 6, to select cable configuration that best suits your
application. If the "loop-back" configuration is selected, use caution when forming the loop as the
minimum bend radius for the cable is 25mm (0.98").
It is recommended that the cables be tied together using 14 AWG copper wire or equivalent stainless
steel tie wire hand-twisted only around the cables within 2" (50 mm ) of the End Seal and approximately
every 6 m (20 ft) along the length of the pipe. This will prevent the cables from coiling up inside the pipe,
which could lead to pipe blockage or freeze-up.
For pushing cable into pipe, straighten cable as much as possible for easier insertion; push cable in slowly.
The cable contains Footmarks (numbers printed on the cable Outer Jacket every 30 cm (12") so the user
can easily determine the length of cable used/remaining or as a reference point. For installations with a
Temporary Moisture Seal, cut the Temporary Moisture Seal off. Pull the cable through the
Compression Fitting Assembly such that it extends 30 cm (12") beyond the Compression Fitting Assembly
and install the power connection or End Seal. See page 9 for End Seal installation instructions.
For pulling cable into pipe, insert fish tape and attach to Pull Cord.
• Use caution to avoid damage to End Seal or Temporary Moisture Seal while pulling cable into pipe –pull
slowly and gently (max. force 220 N (50 lbs)) according to A or B below.
A. If the Pull Cord is installed at the Power Splice end (with Temporary Moisture Seal):
• Pull cable into pipe such that the Temporary Moisture Seal/Pull Cord has completely exited the pipe.
• Cut cable at Power Splice end such that Pull Cord and Temporary Moisture Seal are removed and
cable extends at least 30 cm (12") beyond Compression Fitting Assembly. For reference, refer to the
Footmarks.
