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.

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.

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.

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 thick-
nesses of 9610 application tape or equivalent.
Provide extra heat at valves and spigots by
wrapping each with 1 foot (30 cm) of addition-
al heating cable, overlapping 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 applica-
tion tape or equivalent, tape the end seal to
the pipe as shown in Figures 1, 2, and 6.

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.
