GENERAL
Read and follow these instructions to minimize risks of electric
shock or fire. Save these instructions for future reference.
The electric heating element(s) supplied herein are of rugged con-
struction and if properly installed, operated and maintained, are
designed for long life and dependable, trouble-free service.
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 conse-
quences of failure could result in personal injury or
property damage, back-up controls are essential.
INSTALLATION
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. Clamp-on heaters should be securely clamped to clean, smooth,
metal surfaces. No insulation should contact sheath.
4. Cartridge heaters, when inserted, should be provided with snug fit-
ting holes. Use heat transfer and release compound as required.
