Special Notes
ELECTRIC SHOCK HAZARD.
All electric heating equipment installations must be performed
by qualified personnel in accordance with the local electrical codes and standards and must be
effectively grounded to eliminate shock hazard.
FIRE/EXPLOSION HAZARD FOR HAZARDOUS LOCATION HEATERS.
This heater shall
be used with protection controls as follows:
Liquid Immersion Applications
a. Liquid level control to maintain all the heating elements totally immersed at all times, in
conjunction with temperature controls to limit the liquid temperature below the maximum
allowable process design temperature, or
b. Heating elements sheath temperature controls to limit to the maximum allowable sheath
design temperature
Gaseous and/or vapour phase immersion applications
a. Heating elements sheath temperature controls to limit to the maximum allowable sheath
design temperature.
FIRE/EXPLOSION HAZARD.
Do not exceed the ratings of the flange as listed in ANSI BI6.5.
Do not operate the heater in the presence of combustible gases, vapours, dusts or fibres unless
the heater is specifically marked for the hazardous location and heater operating temperature
does not exceed the temperature code rating. Corrosion of the sheath could result in a ground
fault which, depending upon the fluid being heated, could cause a fire or an explosion.
FIRE HAZARD.
If a thermostat is provided, it is designed for temperature control service only.
Since the thermostat does not fail safe, it should not be used for temperature limiting duty. Wiring
to this device is the users' responsibility.
Heaters are capable of developing high temperatures, therefore extreme care should be taken to:
a. Use explosion-proof terminal enclosures in hazardous locations;
b. Maintain distance between heater and combustible materials.
