step 5.
Install the insulation
Thermal insulation must be used. It protects
the Frostex heating cable from damage and
helps keep the pipes from freezing. Before
you insulate, be sure the Frostex heating
cable is undamaged—no nicks or cuts—and
the braid is intact. Replace the heating cable
if necessary.
5A. Cover the system with the insulation
Cover the pipe, heating cable, connections,
valves, and spigots with clean, dry, water-
proof, fire-retardant thermal insulation, such
as closed-cell foam insulation, as shown in
Figure 7. The insulation must be at least as
thick as selected in Table 1 or 2.
Secure the 9800 FlexFit plug to the insula-
tion with tape or plastic cable ties, being
careful not to cover the light or test buttons.
Warning
labels
Figure 7. Thermal insulation
Do not leave the heating cable exposed,
except for the short distance from the pipe
to the power connection.
Fully insulate and weatherproof all exposed
piping. Put additional insulation on areas
that cannot be heat traced.
5B. Waterproof the insulation
Make sure the thermal insulation is water-
proof and stays dry. Install a watertight
sleeve and a solid cover or a barrier such as
polyethylene sheeting around the insulation
wherever there is any chance that the insu-
lation might get wet.
5C. Install the warning label
Install the orange warning labels on the
insulation with one near the electrical outlet,
as shown in Figure 7.
Additional labels and installation tape are
available from Pentair Thermal Management
in the Frostex 9610 kit.

6A. plug in the heating cable
After installing the heating cable and insula-
tion, remove the clear label that covers the
test and reset buttons. Then, plug the 9800
FlexFit plug into a grounded and properly
installed outlet.
If the Frostex heating cable length is longer
than 40 feet and the air temperature is lower
than 30°F, run water through the pipe before
plugging in the unit. This will warm up the
pipe and help avoid blowing the nonreplace-
able fuse in the 9800 FlexFit plug.
The signal light will go on indicating that the
ground-fault protection device and the fuse
are working properly. However, the light
does not confirm that the heating cable is
properly connected. See Step 7, "Test the
System."
6B. Test the plug
Press the white test button. The red reset
button should pop out from the surface of
the plug and the signal light should go out.
When the red reset button pops out, push it
in to restore power and proceed to Step 7.
If the red reset button fails to pop out, skip
to "Troubleshooting."
If the red reset button pops out imme-
diately but cannot be reset, skip to
"Troubleshooting."
If the signal light does not light, skip to
"Troubleshooting."
Test the system using one of the two follow-
ing procedures.
7A. Test the water temperature
After plugging in the system, wait about an
hour. Turn on a water tap on the Frostex-
protected pipe and test the temperature of
the water. It should feel warm almost imme-
diately because the water heated by the
Frostex heating cable will be briefly running
through the pipe.
If the water is warm, you have completed the
installation.
If the water is not warm, skip to
"Troubleshooting."
