OPERATION
1. Turn fan speed knob to desired speed.
-For fast humidification of a large room or house,
approximately 9 gallon per day.*
-For normal operation.
-For quiet, night time operation or after desired moisture
level is reached.
* Calculations based on ambient room conditions of 70°F
and 30% relative humidity in a room of average insulation.
The correct room humidity display will set itself 10 seconds after
the power cord is plugged into a 120 V outlet.
2. Push the humidity set button up or down, to adjust the
humidity to the desired level. The desired humidity range is
25% to 95%.
The desired humidity level is displayed in small numbers and the
correct room humidity % is displayed in large numbers.
Oncethecurrentroom humiditylevelreachesthedesiredhumid-
ity level, the fan will turn off and the humidity indicator light will
comeon. Thislight indicates thatthehumidifier is stillon and will
again start when the current room humidity level falls below the
desired set level.
If the current room humidity drops below 25% or goes above
95%, the display will blink off and on until the current room
humidity is within the 30% to 90% range.

OFF-SEASON STORAGE
1. Clean and dry Humidifier thoroughly per the CLEANING
sectionabove.Do not leaveany waterin the Unit when storing.
2. Dispose of the Evaporative Filter Pad. Do not store used
Evaporative Filter Pad in the Humidifier.
3. Place Humidifier back into its carton and store in a cool
dry place.
FILTER CARE
The Filter inside your Humidifier plays a very important part in its
operation. In order to maintain peak performance, it is highly
recommended to use only AIRKING REPLACEMENT FILTERS.
Some imitation filters do not comply with AirKing’s quality standards,
resulting in decreased performance of your Humidifier.
CAUTION: To prevent electric shock, always turn Power
Control Knob to OFF position and unplug before servicing.
1. To replace the Evaporative Filter Pad, remove the Jug and Upper
Housing from the Base. Be careful not to let excess water
from pump spill onto furniture or flooring.
2. Remove Evaporative Filter Pad Holder from Base and inspect
Small Water Drip Holes for any blockage.
(Figure 6)
3. To open the Filter Holder apply outward pressure to the two
snaps and it will hinge open. Remove used Filter from Holder
and discard. (Figure 7)
4. Insert new Filter into Holder, snap closed, and reinstall Holder
into Base. (Figure 7) The Filter will only fit into the Holder one
way. Make sure the Rounded side of the Filter Holder is facing
outward. Replace Upper Housing, then Water Jug into Base.
5. To increase the life of your Filter Pad turn
Filter around (so the bottom of Filter is
now at the top).
6. Filter life may be extended by cleaning
the Filter in a 20% vinegar solution. To
clean Filter, mix one part undiluted vin-
egar with four parts warm tap water. Soak the Filter in this
solution for 20 minutes, rinse Filter thoroughly with warm wa-
ter to remove vinegar odor.
DO NOT FLATTEN, SQUEEZE ORTWIST FILTER WHEN CLEANING.
7. Discoloration of the Evaporative Pad is normal after
extended use.The discoloration is caused by mineral deposits
in the water, and the degree of discoloration will vary depending
upon the amount of mineral content in the water.When the Fil-
ter surface area is thoroughly discolored, or you notice
reduced water usage, it is a good indicator that the Filter Pad
needs to be replaced. The Evaporative Pad should be
replaced at least once every season.
CLEANING
1. Regular cleaning is necessary to ensure proper and
efficient operation.The frequency of cleaning depends on
the amount of impurities which may be found in the water
or how often the Humidifier is in operation. In either in-
stance, it is recommended that the Humidifier be
cleaned at least once a week.
NOTE: Unscrew bottom of Water
Jug for easy cleaning.
(Figure 8)
CAUTION: Make sure bottom of
Jug is securely fastened to Jug
before reinstalling into Base.
2. TO DESCALE BASE, JUG
AND DRIP SHIELD: Mix one
part undiluted white vinegar
with four parts warm tap wa-
ter. Let vinegar solution
stand for 20 minutes then
wipe away any scale buildup
using a soft brush or cloth.
Do not use soap or deter-
gents and never use an
abrasive cleaner.
3. TO DISINFECT BASE, JUG
AND DRIP SHIELD: Fill Jug with 1 teaspoon of chlorine bleach
and 1 gallon of water. Let solution stand for 20 minutes.Carefully
empty Jug and rinse well with water until bleach smell is gone.
4. Commercial"Descalers" and "Bacteriostats"areavailableatyour
local home improvement center.
5. Do not operate Humidifier when there is still cleaner in the water.
