• Ensure the device is connected to a reliable power source with proper grounding to eliminate static electricity.

• Keep the equipment away from flammable gases, materials (e.g., paper), and heat-sensitive objects to prevent fire hazards.

• The device generates high-temperature air. Avoid contact with heating elements, nozzles, or obstructing the airflow to prevent burns or damage.

• Attach the appropriate nozzle to the device's air outlet tube. After assembly, place the handle on the holder.

• Connect the AC power cord to the rear socket, ensuring the device is securely grounded.

• Replace damaged heating elements with identical models: match power ratings, physical dimensions, wire gauges, and ensure sensor wires (KP+ and KP-) are correctly connected. Use parts when possible.

• The sensor uses a K-type thermocouple; polarity must be observed during replacement to avoid temperature instability.

• When replacing the heating element:

  1. Remove the old element.

  2. Wrap the new element with mica paper.

  3. Reassemble in reverse order, ensuring correct polarity for sensors and heating wires.

  4. Test functionality before use.

• The device features automatic fault detection with visual (error codes) and audible alerts:

  • ERR1: Heater failure or incorrect sensor cable polarity. Disconnect power to troubleshoot.

  • ERR2: Overheating or improper handle placement. Disconnect power to correct.

• Address alarms immediately by resolving underlying issues before resuming operation.

Reasons why the product fails to start or the screen doesn't light up after plugging in the power:
First, the customer can replace the power cord. If the issue persists, it might be due to damage to the terminal wiring caused by rough handling during shipping. Here is a tutorial on inspecting the terminal wiring.
