Self-Regulating Heating Cables for Pipes
CHOOSING A CABLE
–
Make sure to choose a cable longer than the pipe ensure coverage.
NOTE: For each valve or spigot on pipe an additional foot of cable is needed. When the cable is longer than the pipe,
spiral the excess cable around the pipe length evenly.
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 k 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
DR-003 fiberglass application tape
or nylon cable ties. Do not use vinyl
tape, metallic products or wire.
INSTALLING THERMAL INSULATION
1. Before insulating, inspect the cable to
ensure that it is free of mechanical
damage, such as gouges or cuts, etc.
2. Cover the pipe, cables, connections,
valves with at least 1/2” (12.7
mm) thick fiberglass insulation or
equivalent. DO NOT leave the
cables exposed.
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 give power to the
cable. Standing water in the pipe
should feel warm within one hour.
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.
