This component is an electrical device which must be

installed correctly to ensure proper operation and to

prevent shock or fire. Read these important warnings and

carefully follow all the installation instructions.

• To minimize the danger of fire from sustained

electrical arcing if the heat ing cable is damaged or

mis installed, use a ground fault protection device

(GFPD). Arcing may not be stopped by conven tion al

circuit breakers.

• Component approvals and performance are based on

the use of specified parts only. Do not use substitute

parts or vinyl electrical tape.

• The black heating cable core and fibers are conductive

and can short. They must be properly insulated and

kept dry.

• Damaged bus wires can overheat or short.

Do not break bus wire strands when scoring the

jacket or core.

• Heat damaged components can short. Use a heat gun

or a torch with a soft, yellow, low-heat flame, not a

blue focused flame. Keep the flame moving to avoid

overheating, blistering, or charring the heat-shrinkable

tubes. Avoid heating other components. Replace any

damaged parts.

WARNING: Overheating heat-shrinkable tubes will

produce fumes that may cause irritation. Use adequate

ventilation and avoid charring or burning. Consult MSDS

for further information.
