Check the following before you connect the xTool Smoke Purifier to a power supply for the first time to ensure operation safety and stability.
1. Whether the surface of the purifier chassis is damaged.
2. Whether the filters are properly placed in the chassis.
3. Whether the lid is properly fitted on the chassis.
4. Whether the power switch is OFF.
5. Refer to the following steps to disable the purifier detection in software if you are using it in Laserbox Rotary. Otherwise, the machine will falsely report a fault code.

Step 1: Connect the purifier to a power supply, and check whether the power plug is properly connected.
Step 2: Turn on the purifier.
Step 3: Rotate the rotary knob to start the purifier and set the airflow as required. After processing, rotate the rotary knob to turn the purifier off and turn off the power switch.
