Attaching Cable to Pipe
1.
Prior to installing the cable, be sure all piping is dry, and any sharp surfaces are removed.
2.
Attach heating cable to pipe with straight, spiraling or multiple tracing
3.
If the heating cable is the same length as the pipe, run it straight along the bottom of the pipe. If
two cables are required, position them in the 4 and 8 o'clock positions. If three cables are required,
position them in the 11 o'clock or 1 o'clock positions and 4 o'clock and 8 o'clock positions.
4.
If the cable is less than double the pipe length, spiral the cable over the length of pipe.
5.
Any excess cable remaining at the end of the pipe can be doubled back along the pipe.
6.
Be sure to include any additional heating cable required for valves, spigots, etc.
7.
Secure the cable to the pipe with fiberglass application tape or nylon cable ties. Do not use vinyl
tape, metallic products or wire.
Maintenance Checks
1.
Only qualified persons should service or install the system.
2.
Check yearly for any damage to the heating cable and check any ground fault protection device for
proper operation. If any damage to cable is found, DO NOT operate until it is replaced.
