Ceramic Band Heater Check List: •The surface where a heater willbe mounted must be clean and the heater maintained free of all contaminants that might cause a short circuit in the heater (typically conductive liquids).•To prevent overheating, Watlowrecommends installing an appro- priate temperature controller manufacturer and checking the correct performance of the thermocouple specifications.•Do not use in environmentscontaining combustible gases or vapors.•Keep all electrical connectionsproperly protected to avoid electrical hazards to machine operators.•Do not over tighten clamps supplier to thepoint where serrated side folds begin to collapse. Ceramic band heaters utilize radiation heating and excessive force may breakceramic insulators.
