Maintenance
Cleaning the Humidifier
Regular cleaning is essential for optimal performance and hygiene. The SimpleTank System is designed for easy cleaning:
- The water tank features an integrated carrying handle and a removable cap for easy access.
- The outlet grill is also removable to facilitate cleaning.
- All surfaces that come into contact with water are curved with no sharp corners, making them easy to wipe down with soap and water.
Wick Replacement
The humidifier uses wick filters that should be replaced periodically. The frequency of replacement depends on water hardness and usage. Wicks can sometimes be extended by soaking them in vinegar.
Troubleshooting
If you encounter issues with your Vornado EV100, consider the following:
- No Humidity Output: Ensure the wick is fully touching the water in the base and covering all air intake slots. Evaporative humidifiers may take time to raise humidity, especially in very dry or large spaces.
- Leaking: Refer to the owner's guide for detailed instructions on checking and testing your unit for leaks. Ensure the tank is correctly seated and free from cracks.
- Noise: Some fan noise is normal. If the noise is excessive or unusual, it may indicate a defect. Contact customer support if concerned.
- Blue LED Lights: The control panel lights dim after a few seconds. If they remain excessively bright, consider using LED dimming stickers.
