WARNING
FIRE/EXPLOSION HAZARD FOR EXPLOSIVE ATMOSPHERE 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.
b. Terminal box internal surface temperature control to limit the surface
temperature of the terminal box
c. Heater flange surface temperature control to limit the surface
temperature of the flange.
d. Heating elements sheath temperature controls to limit to the maximum
allowable sheath design temperature
e. Earth fault or earth leakage current protection device to protect against
arcing and sparking during an earth fault.
Gaseous and/or vapour phase immersion applications
a. Heating elements sheath temperature controls to limit to the maximum
allowable sheath design temperature.
b. Terminal box internal surface temperature control to limit the surface
temperature of the terminal box
c. Heater flange surface temperature control to limit the surface
temperature of the flange.
d. Earth fault or earth leakage current protection device to protect against
arcing and sparking during an earth fault.
