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. >
