[0032] The detailed connection means are well known in the art; Figure 1-3 As shown, check the equipment: Make sure all components of the heater are intact, including the L-shaped heating structure, insulation material 4, housing and wiring structure. Make sure the equipment is placed on a stable and dry workbench with no flammable items around. Put the two L-shaped heating plates together and make sure they are tightly connected. Use the buckle 1 and the lock 9 to fix the two L-shaped heating plates together to ensure the stability of the heater. Fix the polymer board 5 in the bracket 7 to ensure it is firm.

[0033] Connect the wire to terminal 11, making sure the connection is firm and well insulated; confirm that all electrical connections are not exposed and there is no risk of short circuit. After ensuring that the power connection is correct, turn on the power switch.

[0034] Set the required heating temperature according to actual needs and start the heater.

[0035] Observe the working status of the heater and confirm whether the heating component is working normally and there is no abnormal sound or smell.

[0036] Place the material to be heated on the heater, ensuring good contact with the heating plate to achieve the best heating effect. Check the temperature regularly to ensure it is within the set range to avoid overheating.

[0037] After completing the heating operation, turn off the power switch first and wait for the heater to cool down naturally.

[0038] The original heater is a heat conduction type, and the heating plate must be fastened to the heated object. One heater must be fixed with as many as 16 φ8~φ10 screws. Long-term thermal expansion and contraction will cause the screws to rust, making replacement very troublesome and time-consuming.
