Position the water bottle back into the humidifier base to the right of the grille. The “Side Fill Cap” must be facing outward. When positioned properly, the plunger will open and water will flow into the base. The base will hold the entire contents of the water bottle. Allow up to one minute for the water to flow into the base. Once the bottle is empty, remove it and refill it as mentioned earlier. Return it to the right side of the grille. The humidifi- er is now filled to capacity.
The water bottle may be filled at anytime as necessary during operation. To benefit from less frequent filling let the humidifier exhaust both the water from the bottle and base before filling.
The unit is now ready for operation.
Operating Humidifier Controls
The operating controls of your MoistAir whole house humidifier are located towards the front of the humidifier.
Familiarize yourself with the controls. Refer to the diagram of the control area for the correct nomenclature used in this manual.
To Operate the Controls
Power Light
When the unit is plugged in and turned on, the red power light will come on. It will stay on until the unit is turned off ( 
) or unplugged.
Humidity Control:
Adjust the amount of
humidity depending on your needs. The humidifier will turn on and off as required to maintain level of humidity selected. A medium setting (half way between the controls rotation) is recommended, but there are times when low or high amount of humidity may be preferred. For con- stant operation of humidifier, rotating the control all the way clockwise allows for the maximum amount of humidity to be evaporated into the air continuously.
IMPORTANT: Water damage may result if condensation starts to form on win- dows or walls. Humidity Control setting should be lowered until condensation no longer forms.
Speed Control
This humidifier has a three speed fan con- trol switch. ( 
) - Low, ( 
) - Medium and
( 
) - High). The maximum humidity output is obtained with the fan control on
high ( 
).
The higher the air flow speed, the more water is evaporated and released into the air. Low speed (
) is the quietest and is also provided for conditions that may not require as high an evaporation rate.
Refill Light
When the unit has a small amount of water left in it, the amber refill light will come on and the unit will automatically shut off.
