RECIRCULATING HUMIDIFIER

Model 1100

IMPORTANT SAFETY INSTRUCTIONS

READ AND SAVE THESE INSTRUCTIONS

Congratulations on your purchase of the Recirculating Humidifier. Featuring the unique use of pump

driven water circulation, this unit provides exclusive features that no other humidifiers offer.

IMPORTANT INFORMATION and FEATURES

Your Recirculating Humidifier is an EVAPORATIVE TYPE
HUMIDIFIER. This means that the air being drawn through

the moistened filter naturally evaporates the water and dis­perses INVISIBLE MOISTURE into the air. This type of hu-
midifier DOES NOT PRODUCE MIST, WATER DROPLETS,
STEAM OR EXCESSIVE CONDENSATION associated with
other types of humidifiers.

EXCESSIVE HUMIDITY CAN OFTEN LEAD TO
UNANTICIPATED PROBLEMS. Air containing water

droplets or mist can create a good habitat for the growth
of mold and mildew.

Misting units often oversaturate the air, while the
Lasko Recirculating Humidifier reaches a maximum
humidity output level without oversaturating. With a
properly operating Evaporative Humidifier, the
evaporation rate increases naturally when the air is
dry. When the humidity in your home is high, mois­ture output automatically decreases to help prevent
damaging condensation.

The Watershow Viewing Window and Water Level In­dicator provide a visible way for you to know that
your Recirculating Humidifier is operating. As air
passes over the filter, the humidity in the room will
increase, and the water level in the Unit will begin
to decrease.

Unlike misting humidifiers, the Evaporative Filter in your
Recirculating Humidifier also traps unwanted minerals that
reside in normal tap water. This filtering also assures there
is NO WHITE DUST dispersed into the air.

IMPORTANT SAFETY INSTRUCTIONS

When using electrical appliances, especially where
children are present, basic precautions should always be
followed in order to reduce the risk of fire, electric shock
and injury to persons... Including the following:

1. To prevent possible electrical shock, always turn

Humidifier off and unplug before filling, servicing
or moving.

2. Always place Humidifier on a stable, flat, level

surface. Locate Power Cord so the Humidifier or other
objects are not resting on it. Keep the Cord away from
room traffic.

3. Do not place Humidifier near a heat source such as

stoves, radiators or heaters.

4. This appliance is equipped with a polarized plug

(one blade is wider than the other). To reduce the
risk of electrical shock, this plug is designed to fit
in a polarized outlet only one way. If plug does
notfit, contact a qualified electrician. Do not at­tempt to defeat this safety feature.

5. Never tilt or attempt to move the Humidifier while

it is operating.

6. Always direct air flow away from walls or furniture

as excessive moisture may cause damage.

7. Humidifiers require regular cleaning to maintain
proper operating conditions. Refer to Cleaning

Instructions for proper cleaning procedures.

8. Do not place Humidifier on an electrical appliance.

1. It is recommended that all Humidifiers be cleaned prior
to use. Please read Cleaning Instructions for Base
Reservoir cleaning.

FILLING and REFILLING

2. Remove the Upper Housing from the Base. Make sure

that the Evaporative Pad is properly placed in the Base
and that the Pre-Pump Filter in the bottom of the Base
is secured to its Posts.

3. Be sure that the Water Funnel is snapped into place. If

Funnel is not completely engaged, water may leak out
through Intake Grill.

(Figure 2)

Water Funnel

4. Even though your Humidifier will produce approxi-

mately 2.5 gallons in a 24 hour period*, the water ca­pacity (amount of water the Humidifier will hold at one
time) is 1.45 gallons.

5. You may fill your Recirculating Humidifier two

different ways:
A) Fill the Base Reservoir with cool tap water to the

Water Line found on the Evaporative Pad Holder or
Base.

(Figure 3A)

B) Replace the Upper Housing on the Base and push

Water Lens down to pour water into the Humidifier
until the Water Level Indicator, found on the
Intake Grill, registers full.

(Figure 3B)

Do not overfill and never use hot water.

Housing. Doing so may cause
damage and personal injury.

Do not overfill. Overfilling the Unit
may cause motor damage.

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.

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 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, high or low to regulate
desired amount of humidity.

Figure 4

(Figure 4)

HIGH: For fast humidification of a
large room. This setting will
provide approximately 2-1/2
gallons of moisture output in a 24

hour period.*
LOW: 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
consumption will be low.

5. Direct the moisture by turning the Directional Exhaust
Grill on the top of the Humidifier to the desired direc­tion. Be careful not to direct airflow towards walls or
furniture, as excessive moisture may cause damage.

6. Refill Humidifier when Water Level Indicator is near
empty, or when no water is visible in Water Lens while
Power Indicator Light is ON.

7. 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 or bacteria.

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 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.

3. Remove Evaporative Pad Holder from Base and inspect

Small Water Drip Holes for any blockage.

Filter

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.

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 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.

The Replacement Filter to be used in this unit is:

The Lasko Replacement Evaporative Pad Model THF 11

(Available separately)

7. To clean inside of Water Lens, remove Water Funnel

Screw and discard. The Screw is to secure the Water
Funnel during shipping and DOES NOT need to be
replaced. Once the Screw is removed slide the Water
Funnel away from Intake Grill, until it has been
removed.

You may now clean inside of the Water Lens and Chassis
area. Make sure the Water Supply Nozzle (Inset) is not
clogged or the unit Will not work properly.

(Figure 8a)

This can easily be cleaned with a pipe cleaner or
toothpick. Replace Funnel back in its original position,
being sure to slide into position until it is flush with
the Extended Tabs.

IMPORTANT:
Make sure nozzle
is clear of
mineral and dirt
build up.

8. TO REMOVE SCALES from inside of Base and Float,

use undiluted white vinegar. Let vinegar stand in Base
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.

9. TO DISINFECT BASE, fill with one gallon of water and

one teaspoon of chlorine bleach. Let solution stand for
20 minutes, stirring occasionally to wet all surfaces.
Carefully empty solution and rinse Base thoroughly with
warm water to remove bleach odor, Refill Base with
cool tap water.

10. 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.

11. Commercial "Descalers" and "Bacteriostats" are

available at your local home improvement center.

12. Do not operate Humidifier when there is still cleaner
in the water.
