Installation Steps

  1. Instructions for using a heat gun or torch: Read important warnings on page 1 and follow safety precautions provided with heat gun or torch. When using a torch, use a soft yellow, low-heat flame. Apply just enough heat to do the job. Keep torch or heat gun moving continuously to distribute the heat evenly to avoid overheating, blistering, or charring the heating cable and heat-shrinkable tubes. Replace any heat-damaged parts.

  2. Remove clear plastic backing.

  3. Center the sleeve over the area to be covered. The damaged section must be less than 10 inches long.

  4. Wrap around so that the grooved rails butt together. Slide metal channel onto rails as shown. Extend metal channel beyond ends of the sleeve.

  5. Using the heat gun or propane torch, begin heating the metal channel first, for about 30 seconds. Shrink sleeve by heating from the center outward to the ends. Continue heating until adhesive flows out both sides.

  6. Allow assembly to cool for about 10 minutes. Cut off the metal channel and rail, using a utility knife. Be careful not to cut the heating cable.

  7. Completed assembly. Leave these instructions with the end user for future reference.

Warnings and Cautions

WARNING:

The heating cable 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.

To minimize the danger of fire from sustained electrical arcing if the heating cable is damaged or improperly installed, and to comply with Chemelex, agency certifications, and national electric codes, ground-fault equipment protection must be used. Arcing may not be stopped by conventional circuit breakers.

Component approvals and performance are based on the use of Chemelex specified parts only. Do not use substitute parts or vinyl electrical tape.

The black heating-cable core is conductive and can short. It 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.

Keep components and heating-cable ends dry before and during installation.

Bus wires will short if they contact each other. Keep bus wires separated.

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.

Megohmmeters operate at high voltage. This voltage is hazardous and possibly lethal. Read and follow all instructions included with the instrument you are using.

CAUTION:

HEALTH HAZARD: Overheating heat-shrinkable tubes will produce fumes that may cause irritation. Use adequate ventilation and avoid charring or burning. Consult MSDS RAY4566 for further information.

AVERTISSEMENT:

Le câble chauffant électrique doit être installé correctement pour éviter les risques d'incendie ou de décharge électrique. Lisez attentivement les mises en garde suivantes et suivez les instructions d'installation.

Pour réduire le danger d'incendie causé par un arc électrique continu, si le câble chauffant est endommagé ou mal installé, et pour être conforme avec Chemelex, les organismes de certification et les codes applicables, il est impératif d'utiliser une protection par disjoncteur différentiel. Un disjoncteur ordinaire peut ne pas être assez sensible pour prévenir les arcs continus.

Les homologations et les performances des composants sont basées sur l'utilisation de pièces spécifiées par Chemelex seulement. N'utilisez pas de pièces de rechange ou de ruban isolant en vinyle.

Le noyau du câble chauffant noir est conducteur et peut occasionner des courts-circuits. Il doit être correctement isolé et gardé à sec.

Les fils omnibus endommagés peuvent surchauffer et occasionner des courts-circuits. Ne cassez pas les brins du fil omnibus lorsque vous entaillez la gaine ou le noyau.

Les composants et les terminaisons du câble chauffant doivent être tenus au sec avant et pendant l'installation.

Les fils omnibus peuvent être court-circuités s'ils se touchent. Tenez les fils omnibus éloignés les uns des autres.

Les composants endommagés par la chaleur peuvent se court-circuiter. Utilisez un pistolet thermique ou un chalumeau avec une flamme douce, jaune et de faible chaleur, pas une flamme bleue focalisée. Maintenez la flamme en mouvement pour éviter la surchauffe, la formation de cloques ou la carbonisation des tubes thermorétractables. Évitez de chauffer d'autres composants. Remplacez toute pièce endommagée.

Les mégohmmètres utilisent une haute tension. Cette tension est dangereuse et peut-être mortelle. Lisez et respectez toutes les instructions fournies avec l'instrument que vous utilisez.

MISE EN GARDE:

DANGER POUR LA SANTÉ: La surchauffe des gaines thermorétractables produit des fumées qui peuvent provoquer des irritations. Utilisez une ventilation adéquate et évitez de les carboniser ou de les brûler. Consulter les fiches techniques santé-sécurité RAY3122 et ITCSN pour plus d'informations.
