5. Setup
- Unpack: Carefully remove all components from the packaging.

- Fill Water Tank: The humidifier features a split design for easy filling. Remove the top section to access the water reservoir. Fill the 16L tank with clean water. Distilled water is recommended to minimize mineral buildup. Do not exceed the 'MAX' fill line.
- Assemble Hoses: Connect the desired flexible hoses and nozzles to the mist outlets on the top of the unit. Use the various adapters to customize the mist distribution for your specific setup (e.g., grow tent, large room).
- Connect Sensor Probe: Plug the detachable wired sensor probe into its designated port on the unit. Place the probe in the area where you want to measure and control humidity.
- Power On: Plug the power cord into a standard 120V electrical outlet.

6. Operation
- Power On/Off: Press the On/Off button to turn the unit on or off. The digital display will illuminate.
- Adjust Mist Level: Press the Mist button to cycle through the 4 available mist output levels. The maximum output is 1400ml/h.
- Set Target Humidity: Press the Humidity button to adjust the desired humidity level. The range is 35% to 95% Relative Humidity (RH) in 5% increments. The humidifier will automatically operate to maintain this set humidity.
- Set Timer: Press the Timer button to set an operating duration from 1 to 12 hours. If you desire continuous operation, do not set the timer.
- Hose Direction: When using the extendable hoses, ensure the mist outlet is hung diagonally upwards. Directing the mist outlet downwards may cause water to accumulate in the pipeline and drip.
- Low Water Indicator: The unit will automatically shut off and display a low water indicator when the tank needs refilling.

7. Maintenance
Regular maintenance ensures the longevity and efficient operation of your humidifier.
- Cleaning the Water Tank: The split design allows for easy access to the water tank for cleaning. Regularly clean the tank to prevent mold, mildew, and mineral buildup. Use a soft brush or cloth and a mild cleaning solution if necessary. Rinse thoroughly.
- Cleaning the Mist Outlet/Hoses: Periodically check the mist outlets and hoses for any blockages or mineral deposits. Clean as needed to ensure unobstructed mist flow.
- Water Quality: Using distilled or demineralized water is highly recommended to prevent white dust (mineral residue) and extend the life of the ultrasonic transducer.
- Storage: If storing the humidifier for an extended period, ensure the unit is thoroughly cleaned and dried. Store in a cool, dry place.
8. Troubleshooting
- No Mist Output:
- Check if the water tank is empty. Refill if necessary.
- Ensure the unit is properly plugged in and powered on.
- Verify that the mist outlets and hoses are not blocked.
- Water Accumulation/Dripping from Hoses:
- Ensure the mist outlet of the hose is hung diagonally upwards. Water can accumulate if the hose is directed downwards.
- Inaccurate Humidity Readings:
- Ensure the sensor probe is placed correctly and is not obstructed or wet.
- Allow time for the sensor to stabilize in the environment.
- Unit Not Responding:
- Unplug the unit, wait for a few minutes, and then plug it back in.
- Ensure the power outlet is functional.
