This component is an electrical device that must
be installed correctly to ensure proper operation
and to prevent shock or fire. Read these important
warnings and carefully follow all of the installation
instructions.
• Do not use substitute parts or vinyl electrical
tape.
• Damaged conductors can overheat or short.
Do not break conductor wire strands when
removing insulation.
• To minimize the danger of fire from sustained
electrical arcing if the heating cable is damaged
or improperly installed, and to comply with the
requirements of nVent, agency certifications,
and national electrical codes, ground-fault
equipment protection must be used on each
heating cable branch circuit. Arcing may not be
stopped by conventional circuit breakers.
• Keep components and heating cable ends dry
before and during installation.
• Heat guns or torches can cause fire or explosion
in hazardous areas. Be sure there are no
flammable materials or vapors in the area
before using these tools.
• Wrap exposed conductors with supplied tape
strips to prevent shorts.
