FIRE/EXPLOSION HAZARD. This heater is not intended for use in hazardous atmospheres where flammable vapors, gases, liquids or other com­bustible atmospheres are present as defined in the National Electrical Code. Failure to comply can result in personal injury or property damage.
Chromalox TTUH and TTUH-CO food equipment heaters are ideal for coffee urns, steam tables, kettles, humidifiers and other commercial uses.
Heater Construction Characteristics A. An opening of 2-7/16” in diameter in the bottom of the tank is
required to insert the heater.
B. High watt density. C. 4” conduit box is mounted to the tank by a tightening bolt.
The system designer is responsible for the safety of this equipment and should install adequate back-up controls and safety devices with their electric heating equipment. Where the conse­quences of failure could result in personal injury or property damage, back-up controls are essential.
GENERAL
ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property dam­age. Heater must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70.
FIRE HAZARD. Since heaters are capable of devel­oping high temperatures, extreme care should be taken to: A. Avoid mounting heaters in an atmosphere con-
taining combustible gases and vapors.
B. Avoid contact between heaters and combustible
materials.
C. Keep combustible materials far enough away to
be free of the effects of high temperature.
D. Keep heater immersed at all times.
