As air moves through the wick, the water evaporates into the air, leaving behind any white dust, minerals, or dissolved and suspended solids. Because the water is evaporated, there is just clean and invisible moist air. As the evaporative wick traps accumulated minerals from the water, its ability to absorb and evaporate water decreases. We recommend changing the wick at the beginning of every season. In hard water areas, more frequent replacement may be necessary to maintain your humidifier’s e

In hard water areas, more frequent replacement may be necessary to maintain your humidifier's efficiency. NOTICE: We recommend using Bemis by Essick Air Bacteria Treatment, whenever you refill the water bottles to eliminate bacteria growth. Follow the directions to determine the proper amount to be added to the 2.75 gallon water bottles. The evaporative wick does not require the use of chelating agent type water treat ments that are intended for use in Rotobelt or Water Wheel type humidifiers. Y

REMOVING SCALE 6) Carefully lift wick from cabinet, allowing any water to drain from it into water channel. Place in sink or tray to finish draining. 7) Remove any remaining water in channel with a sponge. Fill water channel with one 8 oz. cup of undiluted white vinegar. Let solution stay 20 minutes. Remove with a sponge. Clean all interior surfaces with soft brush. Dampen soft cloth with undiluted white vinegar and wipe out water channel to remove scale. 8) Rinse water channel thoroughly with f

Use only the bottles provided. CONTROLS & OPERATION 10) Plug cord into wall receptacle. Your humidifier is now ready for use. The humidifier should be placed at least FOUR inches away from any walls and away from heat registers. Unrestricted airflow into the unit will result in the best efficiency and performance. Set desired levels and speed. 11) Open control panel door by lifting under the tab. Depending on which model, you may have a choice of 2, 4, or variable fan speed allowing you to use t

BOTTLES 7) Fill the bottles with cool, fresh, preferably unsoftened water. If you have only softened water available in your home, you may use it, but you will notice a buildup of minerals on the wick much sooner. The bottles hold 2.75 gallons each. When filling the bottles, be careful not to pressurize them by over filling. Bottle damage can result from this. To reduce carrying weight, the bottle may be partially filled and unit will still operate properly. A fill hose is provided with your hum

The desired humidity level can be manually adjusted between 30 and 90%, using the “Set Humidity” button. 45% RH is the suggested initial setting. 17) The automatic humidistat will turn the humidifier ON when the relative humidity in your home is below the humidistat setting and will turn the humidifier OFF when the relative humidity in the room exceeds the humidistat setting by 6% R.H. This will reduce rapid cycling. When the humidifier is running, you will feel cool, invisible, humid air exitin

Air Care® Filter MODELS 4D7 800, 497 800, 497 300, 447 401, 447 301 AND 427 300 Air Care® models feature a two-stage air filter which attaches to the back of the humidifier. The Air Care® filters the air as it humidifies. 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 of the Air Care® filter is an activated carbon media which absorbs odors from cooking, pets or tobacco smoke. We rec

DISINFECTING RESERVOIR 9) Fill water channel with mixture of one teaspoon chlorine bleach in one gallon water. Let solution stay 20 minutes, swishing every few minutes. Make sure the cleaning solution does not come in contact with the chassis/ power pak. Do not attempt to pour liquid directly through the grill into the humidifier cabinet. 10) Empty water channel after 20 minutes. Rinse with water until bleach smell is gone. Dry with clean cloth or paper towel. 11) Clean all surfaces of the chass

Replace if clogged or hardened with minerals. • Humidistat is not set high enough—increase humidity setting. 3) Too much humidity: • When condensation becomes heavy on cold surfaces in the room, turn the humidistat setting lower or increase the room temperature. 4) Water Leak: • Any hole in the water bottle will allow air to enter the bottle and all the water in the bottle to run out. Do not puncture the bottle in an attempt to drain it faster. 5) Odor: • Bacteria may be present. Clean and disin

If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature. If an extension cord must be used, it should also accept the wide blade plug and meet this electrical rating. 2) Do not place the cord under rugs, near loose drapes, in traffic areas, nor near heat sources or combustible materials. 3) Do not use the humidifier if the cord is damaged. 4) Always unplug the power cord before filling
