1.
Before installing the cable, make sure that all piping is dry and free of any sharp
surfaces and edges.
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 and 8 o’clock positions.
4.
If the cable is less than double the pipe length, spiral the cable over the
pipe length.
5.
Any excess cable remaining at the end of the pipe can be doubled back along
the pipe.
6.
Make sure to include any additional heating cable required for valves, spigots, etc.
7.
Secure the heating cable to the pipe with fiberglass adhesive tape (SSFR03).
Do not use vinyl tape, metallic products or wire. On plastic pipes, secure the full
length of cable with aluminum foil tape (SSFR-ALUTAPE).

ATTACHING CABLE TO PIPE
1.
Before insulating, inspect the cable to make sure that it is free of mechanical
damage, such as gouges or cuts, etc.
2.
Cover the pipe, cables, connections and valves with at least 1/2 in. (12.7 mm)
thick fiberglass insulation or equivalent. DO NOT leave the cables exposed. For
a protection down to -20 °F/-29 ºC, increase insulation to 1 in. (25.4 mm) thick.
3.
Use fire-resistant materials such as fiberglass wrap. Make sure the insulation is
waterproofed (with polyethylene or other vapor barriers) in areas where water
may come in contact with the insulation.
4.
Place the two warning labels on the outer surface of the pipe insulation where
clearly visible and at suitable locations to indicate the presence of electric
heating cable.
5.
After installation is complete, turn the circuit breaker on to power the cable.
The water inside the pipe should feel warm within one hour.
