Place the Honeywell humidifier near an electrical outlet. It must be at least 6 inches away from any walls or furniture.
Hold the handle on top of the water tank and lift straight up to remove the tank from the humidifier. Take the motor housing out of the base of the humidifier. Turn the tank upside down and unscrew the cap.
Fill the tank with cold tap water. If you have hard tap water, use distilled water instead. Replace the cap on the bottom of the tank.
Put the motor housing back in the base. Position the water tank over the humidifier and lower it in place. You will see bubbles. This means water is emptying into the base.
Check that the humidifier switch is turned to the "Off" position. Push the humidifier's plug into an electrical outlet. Make sure your hands are dry when you do this.
Turn the top switch to the desired humidity output. Three black fan blades means full speed, two black fan blades is medium speed and one black fan blade is slow speed. If your humidifier has not run for awhile, turn it to full speed and let it run until the room is at a comfortable humidity.
Set your Honeywell humidifier to the desired humidity once your room has reached this level. Turn the bottom switch counter clockwise until the humidifier shuts off. The Honeywell humidifier will now automatically keep the room at this humidity.
- Some styles of Honeywell humidifiers have electronic settings. In this case, push the up or down button on the front of your humidifier to select your desired level of humidity. Then push the power button to start the humidifier.
