Setup
1. Placement
Place the humidifier on a flat, stable surface at least 6 inches (15 cm) away from walls and furniture. Ensure the mist outlet is not directed at walls or electronics.
2. Filling the Water Tank
The KZF 15L Humidifier features a convenient top-fill design. You can fill the tank in two ways:
- Direct Top Fill: Remove the top cover and pour water directly into the tank up to the 'MAX' line. Ensure no water enters the mist outlet or control panel.
- Removable Tank Fill: Carefully lift the top section (containing the control panel and pump) off the water tank. Fill the water tank separately up to the 'MAX' line. Ensure the power plug of the pump does not get wet. Reattach the top section, ensuring the pump is properly seated at the bottom of the tank.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No mist or low mist output. | Low water level; mineral buildup on transducer; mist outlet blocked. | Refill water tank; clean the transducer with a soft brush; ensure mist outlet is clear. |
| Water leakage. | Improper assembly; damaged tank/seal. | If leaking occurs during initial use, empty the tank and base, then reassemble carefully. Check for cracks or damage. |
| Unpleasant odor. | Stagnant water; dirty tank. | Empty and clean the water tank thoroughly. Use fresh water daily. |
| PM2.5 detector shows high readings. | PM2.5 detectors may misinterpret mist as particles. | This is normal and does not indicate air pollution from the humidifier. |
