CAUTION

CAUTION. 

This document presents the minimum requirement pertaining 

to the installation, operation, and maintenance of the respective 

equipment as required by the manufacturer only. Any additional 

considerations, including but not limited to any design consideration, 

in-service inspection, and fitness-for-service assessment for all pressure 

boundary components to meet any safety principles and local jurisdictional 

regulatory requirements, shall be the responsibility of the user.

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.

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.
