Cable testing and maintenance

Using a 2500-Vdc megohmmeter, check the
insulation resistance between both of the
rectangular (power) prongs on the plug and
the round (ground) prong after installing the
heating cable. Minimum reading should be
1000 megohms.

Record the original values for each circuit, and
compare subsequent readings taken during
regular maintenance schedules to the original
values.

If the readings fall below 1000 megohms,
replace the Gardian W51 cable with a new
unit. Do not attempt to repair the unit.

WARNING! Fire and shock hazard.

Damaged heating cable can cause electrical
shock, arcing, and fire. Do not attempt to
repair or energize damaged heating cable.
Remove it at once and replace with a
new length.

4. Install thermal insulation.

• A reliable Gardian system depends on properly installed and dry,

weatherproofed thermal insulation.

• Ensure that at least 1/2" of preformed foam or equivalent thermal

insulation is used and that all piping, including valves, joints, and wall
penetrations, has been fully insulated as shown in Figure 3.

• For protection to -20°F (-29°C), use 1" thick insulation.

• Install the insulation on the piping as soon as possible to minimize the

potential for mechanical damage after installation.

• Be sure the Gardian W51 label is visible on the outside of the thermal

insulation.

5. Finishing the installation.

• To prevent damage to the heating cable or cord, secure the

power cord (cold lead) with a plastic cable tie, glass cloth tape,
or duct tape as shown in Figure 4.

• Two labels indicating the presence of electric pipe heating cable are

included with the heating cable. Attach the two “Electric Traced” labels
on the outer surface of the pipe insulation at suitable internals to
indicate the presence of Gardian electric heating cable.

6. Starting the system.

• Tyco Thermal Controls recommends that the system be tested per the

“Cable testing and maintenance” section below.

• Plug the heating cable into a 120 V ground-fault protected outlet.

• Check the circuit breaker to verify power to the cable.

• Standing water in the pipe should feel warm within an hour.

Note:

Pipes must be fully insulated.
