CONTROLS AND OPERATION
1. Plug cord into wall receptacle. Your humidifier is now ready for
use. The humidifier should not be near any heat registers.
Place the unit at least FOUR inches away from any walls.
Unrestricted airflow into the unit will result in the best efficiency
and performance.
2. Access the control panel by opening the panel door (427
Model). Depending on which model, you may have a choice of
2 speed or variable fan speed allowing you to use the low
setting for the quietest operation or a high setting for maximum
output.
NOTE: When excessive condensation exists, a lower speed setting
is recommended.
NOTE: Each model has an automatic humidistat. The humidistat will
turn the humidifier on when the relative humidity in your home is
below the humid- stat setting and will turn the humidifier off when the
relative humidity reaches the humidistat setting.
3. For initial operation, set the humidistat at its midpoint “comfort
zone” setting and adjust up or down from there to achieve the
desired humidity level. Turning the Humidity Control knob all the way counterclockwise will
turn the unit off regardless of the relative humidity. This must be turned on again before the
unit will work.
4. One bottle is designed to empty first. The refill light will indicate when the respective bottle is
out of water. When the unit is completely out of water, the motor will shut off.
OPTIONAL AIRCARE® FILTER
The optional Aircare® filter is a excellent means of cleaning the air while using your humidifier. The
first stage of the air filter is a high-efficiency, electrostatically charged filter media which traps dust,
pollen, and airborne pollutants. The second stage is an activated carbon media which absorbs
odors from cooking, pets, or tobacco smoke.
We recommend replacing the AirCare® filter at least once a year and more often if necessary.
When the white filter media is coated with a layer of dust and dirt, it is time to replace the
AirCare® filter. The certified water output of your humidifier will be reduced when using the
AirCare® filter. AirCare® filters are optional and are not required for normal operation of the
humidifier. AirCare® is registered trademark of Essick Air Products.
CARE AND MAINTENANCE
Cleaning your humidifier regularly helps eliminate odors and bacterial and fungal growth.
Ordinary household bleach is a good disinfectant and can be used to wipe out the humidifier base
and bottle/reservoir after cleaning. We recommend cleaning your humidifier at least once every
two weeks to maintain optimum environmental conditions for your home.
We also recommend using Essick Air Bacteriostat Treatment each time you refill your humidifier to
eliminate bacterial growth. Add bacteriostat according to the instructions on the bottle. Please
call 1-800-547-3888 to order Bacteriostat Treatment reference part number 1970.
1. Turn off unit completely counterclockwise and unplug from outlet.
2. Lift out the water bottle and the power pack.
3. Carry bottle and base to cleaning basin. Lift wick from the base allowing the water to
drain. Rinse wick under fresh water only. Do not use soap, detergent, or any other
cleaners on the wick. Leave in sink to drain.
