Ex e II T -W (1) • Glass cloth tape: – GT-66 for installation temperature above 40°F (4°C) – GS-54 for installation temperature above –40°F (–40°C) WARNING: 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. • 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 Pentair Thermal Management, agency certifications, and national electrical codes, groundfault equipment protection must be used. Arcing may not be stopped by conventional circuit breakers. • Component approvals and performance are based on the use of Pentair Thermal Management-specified parts only. Do not use substitute parts or vinyl electrical tape. THERMAL MANAGEMENT SOLUTIONS CAUTION: • Damaged conductors can overheat or short. Do not break conductor wire strands when scoring the jacket or removing insulation. • Keep components and heating cable ends dry before and during installation. • Use only fire-resistant insulation materials, such as fiberglass wrap or flame-retardant foam. • Soldering tools 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. EN-Raychem2SCLSC-IM-H57839 03/13 Health Hazard: Hot solder can burn eyes and skin. Fumes during soldering are irritating to eyes and may cause headache and respiratory system irritation or damage. Prolonged or repeated exposure to rosin flux fumes during soldering may result in allergic reaction in a sensitive person, resulting in asthma symptoms. Consult MSDS VEN0043 for further information. Silicone rubber compound Part B, may generate flammable and explosive hydrogen gas if it comes in contact with an acidic, basic or oxidizing material. Personal contact with the silicone rubber compound may cause slight eye or skin irritation. Consult MSDS VEN0030 and VEN0031 for further information.
