ELECTRIC SHOCK HAZARD. Any installation involv- ing electric heaters must be performed by a quali- fied person and must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard.
FIRE/EXPLOSION HAZARD. Since electric heaters are capa- ble of developing high temperatures, extreme care should be taken to:
A. Avoid mounting heaters in an environment containing combustible liquids, gases or vapors.
B.Avoid contact between heaters and combustible materials.
C.Keep combustible materials far enough away to be free of the effects of high temperatures.
Failure to comply could result in personal injury or property damage.
High heating efficiency, low sheath temperatures, and long heater life result when electric heaters are properly installed.
1.Heater mounting must allow for heater expansion without sacri- ficing heat transfer efficiency.
2.Electric heaters should not be bent or deformed because heater insulation can be damaged, leading to electrical problems and a short heater life.
3.
4.Cartridge heaters, when inserted, should be provided with snug fit- ting holes. Use heat transfer and release compound as required.
