Always carry filled Humidifier carefully. Never
move water filled Humidifier while plugged in.
1. 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.
2. Always be sure that the Power Control Knob is in
the OFF (0) position when plugging Humidifier
into a polarized 120 volt AC wall outlet.
CAUTION: Do not Plug Humidifier into electrical outlet
with wet hands, or electrical shock may occur.
3. Set Moisture Control Knob to regulate desired
amount of humidity.
(Figure 3)
HIGH(3): For fast humidification
of a large room. This
setting will provide
approximately 3
gallons of moisture
output in a 24 hour
period.*
MED (2): For normal operation.
LOW (1): For quiet, night time
operation.
* Calculations based on ambient conditions of 70° F
and 30% relative humidity in a room of average
insulation.
4. Water usage will vary depending upon initial
humidity level in the room. If humidity is low, the
Unit will use water more rapidly until the humidity
in the room is stabilized. If the humidity is already
near or above 50% relative humidity, water con-
sumption will be low.
CAUTION: Be careful not to direct airflow towards walls
or furniture, as excessive moisture may cause damage.
5. Refill Humidifier when water level in the Base is
low.
6. If you do not plan to use your Humidifier for several
days, empty all water from the Unit. Standing water
may provide an environment for the growth of algae
Evaporative Pad

1. It is recommended that all Humidifiers be cleaned
prior to use. Please read CLEANING and
FILTER CARE section, for Base cleaning.
2. Remove the Upper Housing from the Base. Make
sure that the Evaporative Pad is properly placed in
the Base.
(Figure 1)
3. Even though your Humidifier will produce approxi-
mately 3 gallons in a 24 hour period*, the water
capacity (amount of water the Humidifier will hold
at one time) is 1.75 gallons.
4. You may fill your Recirculating Evaporative
Humidifier two different ways:
A) Fill the Base with cool water to level indicated
in Figure 2A.
B) Replace the Upper Housing on the Base and
push Water Lens down to pour water into the
Humidifier
(Figure 2B)
until it reaches the level
indicated in Figure 2A.
Do not overfill and never use hot water.
CAUTION: Do not pour water
through the Exhaust Grill on the
Upper Housing. Doing so may
cause damage and personal injury.
Do not overfill. Overfilling the
Unit may cause motor damage.

OFF SEASON STORAGE
1. Clean and dry Humidifier thoroughly per the
CLEANING and FILTER CARE section. Do
not leave any water in the Unit while storing.
2. Dispose of the Evaporative Pad. Do not store a used
Evaporative Pad in the Humidifier. Do not dispose
of Pad Holder.
3. Place Humidifier back in its carton and store in a
cool dry place.
OPERATION INSTRUCTIONS
CAUTION: Always place Humidifier on a firm and level
surface. Locate the Power Cord so the Humidifier is not
resting on it, and the cord is away from room traffic.
CLEANING and FILTER CARE
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 instance, it is recommended
that the Humidifier be cleaned at least once a week.
CAUTION: To prevent electric shock, always turn
Control Knob to OFF (0) position and unplug before
cleaning.
2. Remove Upper Housing from Base. Be careful not
to let excess water from pump spill onto furniture
or flooring.

FILLING and REFILLING
3.
With water lens pushed
down, the filter may be
removed for cleaning or
replacing.
(Figure 3B)
4. Remove Evaporative
Pad Holder from Base and inspect Small Water
Drip Holes for any blockage.
(Figure 4)
It is important that these Drip Holes remain open at
all times for proper water supply to Evaporative Pad.
5. To increase the life of your Evaporative Pad, unsnap
Holder, remove Pad and flip over.
(Figure 5)
Evaporative Pad life may be extended by cleaning
the Pad in a vinegar solution. To clean Pad, mix
one part undiluted vinegar with four parts warm tap
water. Soak the Pad in this solution for 20 minutes,
rinse Pad thoroughly with warm water to remove
vinegar odor.
DO NOT FLATTEN, SQUEEZE OR TWIST FILTER WHEN CLEANING.
6. 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 Pad surface area is
thoroughly discolored, or you notice reduced water
usage, it is a good indicator that the Evaporative
Pad needs to be replaced. The Evaporative Pad
should be replaced at least once every season.
The Replacement Pad to be used in this unit is:
The Lasko Replacement Evaporative Pad
Model THF 15 (Available Separately)
7. TO
DESCALE BASE AND DRIP SHIELD: Mix one
part undiluted white vinegar with four parts warm
tap water. Let vinegar solution 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.
8. TO
DISINFECT BASE AND DRIP SHIELD: Fill 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.
9. Use a dry soft cloth to wipe the Chassis area, which
includes the motor area. DO NOT use water to clean
the Motor or Switch area. Doing so may result in
electrical shock or damage to the Humidifier.
10. Commercial "Descalers" and "Bacteriostats" are
available at your local home improvement center.
11. Do not operate Humidifier when there is still
cleaner in the water.
