Ensure power supply capacity is greater than the heater’s max power dissipation for stable operation
-
For multiple heating elements, connect in parallel to increase total heating power
Usage Precautions
-
Do not use in flammable or explosive environments
-
Avoid immersion in water
-
Do not strike, puncture, or overlap heating elements
