Precautions when using this product

  • This product is for industrial use only.
  • For the power lead wire, use a cabtyre cable or a heat-resistant electric wire, caulk the tip with a crimp terminal, and securely attach it to the plug terminal. Fasten the heater completely with bolt and nut to the phase flange.
  • Do not use the heat generating part exposed to the air. This will result in overheating due to no water and cause early breakage as well as a fire.
  • Scale (stain/carbide) adheres to the heating part, so check it periodically and clean it before using.
  • Please consult us when using for heating liquids other than water.
  • Horizontal mounting is standard for the heater. Note the exposure of the heater in the case of vertical use.
