7. Troubleshooting Guide
Please read carefully to ensure ultimate performance.

Oil Chamber Overheat Warning
- When using the oil chamber for the first time, let it sit for 3 minutes with the silicone plug open after filling it with atomizing liquid. This allows the cotton to fully absorb the liquid and ensures smooth oil flow.
- Make sure the oil chamber is secured to prevent any leakage or malfunction.
- If the oil chamber has been in use for more than 3 months, it may be worn out and should be replaced to maintain optimal performance.
Spitting or Spraying Oil During Use
- Do not refill the oil chamber while it's hot. Opening the silicone plug at high temperatures can cause excess liquid to flow into the chamber, leading to oil spitting or leakage.
- After sealing the silicone plug, turn the device upside down and gently shake it to release any excess liquid through the outlet.
- For best performance, allow the chamber to cool before refilling, or alternate between two chambers to maintain consistent fog output.
Oil Leaking from the Bottom of the Chamber
- The oil chamber features a connected design, so always close the silicone plug immediately after refilling to prevent liquid from leaking.
- Wipe the bottom air vents with a tissue to remove any residue, then turn the chamber upside down and gently shake to release any excess liquid.
