Attach the heating cable of the pipe
1. Before installing the cable, please make sure the pipe is dry and there is no sharp surfaces.
2. Attach the cable to pipe in straight, spiraling or multiple tracing.
3.
Check the length of the cable and the pipe. If they are the same, run it straight along the bottom of the pipe. If two heating
cables are needed, put them in 4 o'clock and 8 o'clock positions. If three heating cables are needed, put them in the 11
o'clock or 1 o'clock positions and 4 o'clock and 8 o'clock positions. You can check the figure 1 for the details.
If the cable is longer than the pipe and less than double the pipe length. You can spiral the cable over the length of the pipe.
4.
You can suspend a loop by every 10 feet as in Figure 2. You can define the loop length (divide the HEATIT cable length by
your pipe length and multiply by 10). Here is an example: The length of the cable you will use is 75ft and the pipe length is
60ft. You can leave a 12-foot loop of heating cable at every 10-foot section of the pipe. Hold the center position of the loop
and wrap the loop around the pipe. You can slide the wraps along the pipe to make the loop distances even. Secure the
center of the loop to the pipe by the glass tapes. You can check the figure 2 for the details.
5. If there is any excess cable remaining at the end of the pipe, you can double back along the pipe.
6. If there are valves, flanges, spigots etc, you can need to prepare the additional heating cables.
7. You can use JSR03 fiberglass application tape to secure the cable to the pipe. Do not use vinyl tape, duct tape metallic product or wire.
Heating cable test before the thermal insulation
Before installing the thermal insulation, please test the heating cable to ensure there is no any product damage such as
gouges or cuts, etc in the previous installation. Plug cable in, and in approximately 5 minutes, it should feel slightly warm to
the touch. Then unplug the cable.

Install the thermal insulation
1.Use the minimum 1/2"(12.7mm) thick fiberglass insulation
or equivalent thermal insulation materials to cover the whole
pipe, connections, valves, joints, wall penetrations and so on.
2.If the ambient temperature is lower than -20°F(-29°C),
please use 1"thick insulation material.
3.The thermal insulation must be waterproofed(with polye
-thylene or other vapor barriers) in areas where water may
come in and contact with the insulation materials. You can
check the figure 3 for the details.
4.Please use the fire-resistant materials.
5.You can check the figure 4 for the strain relief installation.
Secure the power cord(cold lead) with a plastic cable tie,
glass cloth tape or duct tape.
6.Place warning labels on the outside of the pipe insulation
and the power cord. The warning labels must be put in visible
locations to indicate the presence of the electric heating
cable.
