Step 4.
Attach the heating cable to the
pipe.
4A.
Prepare to install the heating cable.
Begin the installation at the electrical outlet. Leave at least
1 foot (30 cm) of extra heating cable so the ground-fault unit
can be secured to the outside of the thermal insulation, as
shown in Figures 1 and 2. This will relieve any strain on the
heating cable or plug. However, be careful not to leave heating
cable hanging in a loose loop where it could be accidentally
snagged and pulled out.
Make certain you have removed any old heating tapes and
insulation.
Important:
The ground-fault unit and plug must be kept dry.
It is important to include the drip loop to prevent water from
getting into the ground-fault unit.

4B.
Install the heating cable.
Single run method
Run the heating cable in a straight line approximately a third of
the way up from the bottom of the pipe, as shown in Figure 3.
Figure 3. Single run method.
Multiple run method
When two or more runs are required, install the heating cable in
the 4 o’clock and 8 o’clock positions as shown in Figure 4.
When three runs are required, install the heating cable as
shown in Figure 5.
Figure 4. Double runs. Figure 5. Triple runs.
4C. Tape the heating cable and end seal to the pipe.
• Fasten the heating cable to the pipe at 1-foot (30-cm)
intervals, using two or three thicknesses of 9610 applica-
tion tape or equivalent.
• Provide extra heat at valves and spigots by wrapping each
with 1 foot (30 cm) of additional heating cable, overlap-
ping as required.
• If you have excess heating cable at the end of your pipe,
double it back along the pipe where the insulation will
completely cover it as shown in Figure 6. Using 9610
application tape or equivalent, tape the end seal to the pipe
as shown in Figures 1, 2, and 6.
Figure 6. Multiple run installation.
Important:
In a crock or standpipe, run the Frostex heating
cable down and back up the pipe (as shown in Figure 6), so
that the
end seal is well above the ground level and
will not be sitting in water.
