INSTALLATION
WARNING: Never hammer the heater ends.
3.DANGER: Hazard of Fire. Since these heaters are capable of developing high temperatures, extreme care should be taken to:
a.Avoid mounting heaters in an atmosphere containing com- bustible 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 temperatures.
WIRING
WARNING: Hazard of Electrical Shock. Any instal- lation involving electric heaters must be effective- ly grounded in accordance with the National Electrical Code to eliminate shock hazard.
1.Electric wiring to heating elements must be installed in accor- dance with National Electrical Code and local codes by a qualified person. Use copper conductors only.
2.Protection with properly sized fuses/breakers is important to minimize hazards.
OPERATION
1.Do not operate heaters at voltages in excess of that stamped on the heater since excess voltage will shorten heater life.
2.Do not operate under conditions that result in temperatures higher than the recommended maximum, since excess temper- atures can cause premature heater failure.
The maximum recommended temperature on sheath materials normally supplied is:
Stainless Steel Alloy
3.Electrical terminals should be protected from spillage of plas- tics, water, oil and their vapors which can create electrical hazards and/or heater failure.
4.Do not energize heater in free air or at more than rated voltage.
5.Stud heaters are generally used in large banks to allow uni- form tightening of mating parts. All heaters of one group should be energized simultaneously.
MAINTENANCE
WARNING: Hazard of Severe Shock. Disconnect all power to heaters before servicing or replacing heaters.
1.Make certain that both the terminals and heater sheath are free from contact with oil, liquids or other foreign matter.
NOTE: Chromalox cannot be responsible for failures or damage caused by organic contamination in stud heaters. Make certain that the heaters are not exposed to organic contaminants.
2.Check electrical connections at heater terminals and tighten if necessary. This will help avoid hot terminals that may destroy wire insulation or heater terminals.
3.Check overheat operation to insure heater protection.
