Operating the Controls - continued
NOTE: During this time the room humidity level will continue to be monitored and the humidifier will cycle the fan on and off until the filter is completely dry.
Speed Button 
This humidifier is equipped with a
The selected setting is displayed on the digital readout. The higher the setting, the faster water is evaporated and released into the air. F1 (LOW) is the quietest setting and is provided for conditions that do not require a rapid evaporation rate.
Using Your Humidifier
Refill Display
For maximum run time both the bottle and the base should be filled. When both the bottle and the base are empty the display alternates the room humidity reading and “F” (FILL), indicating that additional water is required. Also at this time the unit will automatically switch into DRY OUT MODE and continue to run on the lowest speed until the filter is dry.
Humidity Control 
This button allows you to adjust the humidity to suit your needs. This humidifier will automatically cycle on and off as required to maintain the selected setting. The readout displays both actual (ROOM) and desired (SET) humidity percentage (%) settings when humidity control button is pressed. The ROOM readout has a range of 20% to 95%. If the room humidity level is equal to or less than 20% the display will show a flashing 20.
The SET readout has a range of 25% to 65% and is adjusted in increments of 5%. Initially depressing the humidity button will display the current humidity setting. Each additional press of the button increases the setting by 5%. A SET point of 65% operates the humidifier continuously regardless of the ROOM reading. The humidistat that senses the readings is located on the power cord. Insure that it is free from obstructions.
The fan will shut off leaving you with a dry humidifier that is less prone to mold and mildew growth. If DRY OUT MODE is not desired, refill the humidifier with water and the fan will return to the set speed.
NOTE: Fan automatically switches to lowest speed during DRY OUT MODE.
Check Filter Indicator
The ability of any humidifier to efficiently supply humidity output relies heavily on the condition of the filter. As the filter loads with impurities it gradually loses its wicking capability. When this happens, moisture output is reduced and the humidifier has to work longer to satisfy the selected setting. This humidifier has a check filter reminder timed to appear after 720 hours of operation. When display shows an alternating “CF” and “room humidity” setting at 5 second intervals it is a reminder to check the filter condition.
Humidistat
The humidistat located on the power cord senses the percentage of humidity in the air. It causes the humidifier to cycle on and off to maintain the selected humidity SET point. The fan will turn on if the “ROOM” reading falls 3% below the SET point and will continue to run the humidifier until a reading of 1% above the SET point is achieved. The fan will turn off until the ROOM reading falls 3% below the SET point again.
NOTE: Be sure that the humidistat, which is located on the power cord, is free from obstruction and away from any hot air source.
