CAUTION: Do not pour water through
the Exhaust Grill on the Upper Housing.
Doing so may cause damage and personal
injury.
CAUTION: • Unplug Unit when lling.
• Always place Humidier on a rm level surface.
Locate the Power Cord so the Humidier is
not resting on it, and is away from trafc.
• Be careful not to overll.
• Do not pour water through Exhaust Grill,
doing so may cause damage and personal injury.
• Take extra care to prevent water spillage
that may damage furniture or flooring. The
manufacturer will not accept responsibility for
damage to property caused by water spillage.
• Always be sure the Power Knob is in the OFF
position when plugging Humidifier into a
grounded 120 volt AC wall outlet.
• To prevent risk of electrical shock and injury to
persons, do not plug Humidier into electrical
outlet with wet hands.
1. It is recommended that all Humidiers be cleaned prior to use.
Please read Cleaning Instructions for Base and Jug cleaning.
2. Use the convenient Carrying Handle found on the bottom of
the Water Jug to bring it to a faucet. The Water Jug features a
‘Quick Fill/Quick Empty’ Spout. To ll, hold Jug upside down
by the Handle. Use thumb to press down Stopper Lever, and ll
Jug. Fill the Water Jug with cool tap water. Never use hot water.
(Figure 3)
When the Jug is replaced back into the Base it will quickly empty
to ll Base.
NOTE: While carrying lled Water Jug back to the Humidier, hold
the Handle with one hand, while supporting bottom of Water Jug
with other hand.
3. Place the Water Jug securely in the Base. If positioned
properly, water will quickly pour into Base and automatically
stop when reaching desired amount.
4. When gurgling noise stops lift up the Water Jug to see if it is empty.
Rell if empty. When the Unit is full some water will remain in
the Jug.
5. Even though your Humidier will produce approximately 9.0
gallons in a 24 hour period*, the water capacity (amount of
water the Humidier will hold at one time) is 4.5 gallons.
(3 FULL Jugs).

Figure 5
The presence of water ow in the Water Show Window indicates
the circulation of water to the Filter. (Figure 5)
1. Clean and dry Humidifier thoroughly per the Cleaning
Instructions. Do not leave any water in the Unit when stor-
ing.
2. Dispose of the Evaporative Filter Pad. Do not store used
Evaporative Filter Pad in the Humidier.
3. Place Humidier back into its carton and store in a cool dry
place.
OFF-SEASON STORAGE
NOTE: The Humidier will only turn on when the Humidistat is set to
a high enough setting or when the room humidity is low enough.
Figure 6
The Filter inside your Humidier plays a very important part in
its operation. In order to maintain peak performance, it is highly
recommended to use only LASKO REPLACEMENT FILTERS. Some
imitation lters do not comply with Lasko’s quality standards,
resulting in decreased performance of your Humidier.
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 ooring.
2. Remove Evaporative Filter Pad Holder from Base and inspect
Small Water Drip Holes for any blockage. (Figure 7)
Figure 7
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 8)
Figure 8
4. Insert new Filter into Holder, snap closed, and reinstall Holder
into Base. (Figure 7) The Filter will only t 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 vinegar with
four parts warm tap water. Soak the Filter in this solution for
20 minutes, rinse Filter thoroughly with warm water to remove
vinegar odor.
CLEANING
DO NOT FLATTEN, SQUEEZE OR TWIST 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 depend-
ing upon the amount of mineral content in the water. When
the Filter 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.

1. Regular cleaning is necessary to ensure proper and
efcient operation. The frequency of cleaning depends on the
amount of impurities which may be found in the water or how
often the Humidier is in operation. In either instance, it is
recommended that the Humidier be cleaned at least once
a week.
NOTE: The bottom of the Jug may
be unscrewed for easy cleaning.
(Figure 9)
CAUTION: Make sure bottom of
jug is securely fastened to Jug
before reinstalling into Base.
2. TO DESCALE BASE AND JUG:
Mix one part undiluted white
vinegar with four parts warm
tap water. Let vinegar solu-
tion stand for 20 minutes then
wipe away any scale buildup
using a soft brush or cloth. Do
not use soap or detergents
and never use an abrasive
cleaner.
3. TO DISINFECT BASE AND JUG: 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” are available at
your local home improvement center.
5. Do not operate Humidier when there is still cleaner in the
water.
FILLING and OPERATION
(Jug Holds 1-1/2 Gallons)
(Base Holds 3 Gallons)
Figure 9
6. Turn Power ON to desired speed. (Figure 4)
3 - For fast humidification of a large room or house,
approximately 9 gallon per day.*
2 - For normal operation.
1 - 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.
NOTE: Power Light and Fan are on only when the Humidistat is
turned to a high enough moisture setting.
7. To set Humidistat to desired level turn Knob towards HIGH
until the power is ON. After the room has reached a comfort-
able humidity level, turn the Humidistat Knob slowly towards
LOW until the fan shuts off and the Green Light turns on, the
Humidifier will automatically restart when humidity falls
below this setting. (Figure 6)
