that is likely to accumulate standing water.
If this condition develops, for your safety
disconnect the power supply before
stepping into the water.
■ Never unplug your dehumidifier by pulling
on the power cord. Always grip plug firmly
and pull straight out from the receptacle.
■ Replace immediately all electric service
cords that have become frayed or otherwise
damaged. A damaged power supply cord
must be replaced with a new power supply
cord obtained from the manufacturer and
not repaired. Do not use a cord that shows
cracks or abrasion damage along its length
or at either the plug or connector end.
■ If the receptacle does not match the plug,
the receptacle must be changed out by a
qualified electrician.
■ Turn the dehumidifier OFF and unplug it
before making any repairs or cleaning.
NOTE: We strongly recommend that any
servicing be performed by a qualified
individual.
■ For your safety, do not store or use
combustible materials, gasoline or other
flammable vapors or liquids in the vicinity
of this or any other appliance.
■ All dehumidifiers contain refrigerants,
which under federal law must be removed
prior to product disposal. If you are getting
rid of an old product with refrigerants,
check with the company handling disposal
about what to do.
■ Do not use outdoors.
■ This dehumidifier is intended for
indoor residential applications only.
This dehumidifier should not be used
for commercial or industrial applications.
When using this dehumidifier, always follow basic safety precautions, including the following:
SAFETY PRECAUTIONS
Do not, under any circumstances, cut or remove
the third (ground) prong from the power cord.
For personal safety, this appliance must be
properly grounded.
DO NOT use an adapter plug with this appliance.
The power cord of this appliance is equipped
with a 3-prong (grounding) plug which mates
with a standard 3-prong (grounding) wall
outlet to minimize the possibility of electric
shock hazard from this appliance.
Have the wall outlet and circuit checked by a
qualified electrician to make sure the outlet is
properly grounded.
Where a 2-prong wall outlet is encountered,
it is your personal responsibility and obligation
to have it replaced with a properly grounded
3-prong wall outlet.
The dehumidifier should always be
plugged into its own individual electrical
outlet, which has a voltage rating matching
the rating plate.
This provides the best performance and also
prevents overloading house wiring circuits,
which could cause a fire hazard from
overheated wires.

When first using the dehumidifier, operate the unit continuously 24 hours.
Choosing a Location
A dehumidifier operating in a basement will have
little or no effect in drying an adjacent enclosed
storage area, such as a closet, unless there is
adequate circulation of air in and out of the area.
■ Do not use outdoors.
■ This dehumidifier is intended for indoor residential
applications only. This dehumidifier should not be
used for commercial or industrial applications.
■ Place the dehumidifier on a smooth, level floor
strong enough to support the unit with a full bucket
of water.
■ Allow at least 12–18 inches of air space on all sides
of the unit for good air circulation.
■ Place the dehumidifier in an area where the
temperature will not fall below 41°F (5°C). The coils
can become covered with frost at temperatures
below 41°F, which may reduce performance.
■ Use the dehumidifier in cooking, laundry, bathing
and dishwashing areas that have excessive
moisture. NOTE: Place the dehumidifier away
from the clothes dryer.
■ Use the dehumidifier to prevent moisture damage
anywhere books or valuables are stored.
■ Use the dehumidifier in a basement to help prevent
moisture damage.
■ The dehumidifier must be operated in an enclosed
area to be most effective.
■ Close all doors, windows and other outside openings
to the room.
YES NO
NOTE: The dehumidifier has rollers to aid placement,
but it should only be rolled on smooth, flat surfaces.
Do not attempt to roll the dehumidifier on carpet or
over objects.
How the Dehumidifier Operates
Moist, humid air is drawn over a cold refrigerated
dehumidifying coil. Moisture in the air condenses
on this coil and drains into a bucket (or through
a hose and drain).
Dry, clean air is drawn through the condenser
where it is heated and discharged out the front
grille into the room.
It is normal for the surrounding air to become slightly
warmer as the dehumidifier operates.
This warming effect further reduces the relative
humidity of the surrounding air.
When frost builds up on the evaporator coils, the
compressor will cycle off and the fan will continue
to run until the frost disappears.
When the coil is defrosted, the compressor or fan
(depending on model) will automatically restart
and dehumidifying will resume.

There are 2 ways to remove collected water:
Use the bucket. When the bucket is removed,
the unit will shut off. Empty and replace the
bucket.
IMPORTANT: Do not use the drain tube if using the
bucket to collect water. When the drain tube is
connected, water will flow through it onto the
floor instead of into the bucket.
NOTES:
■ Do not remove the bucket while the
dehumidifier is operating or if it has just
stopped operating. This might cause some
water to drip from the drain pan.
■ The bucket must be in place and securely
seated for the dehumidifier to operate.
Use a hose. Water can be automatically
emptied into a floor drain by attaching the
unit’s drain tube with nozzle and a garden
water hose (not included).
1. Remove the bucket from the front of
the unit.
2. Remove the plug cover from the back of
the unit and store it in a safe location.
3. Insert the tube through the hole in the
back of the unit and securely press it onto
the connector on the front of the unit. Push
the tube around the front connector until
the nozzle is flush with the back of the unit.
4. Secure the nozzle to the back of the unit
with the two screws provided.
5. Cut (as needed) and thread a garden hose
(not supplied) onto the nozzle and lead it
to the floor drain.
6. Replace the bucket in the unit.
NOTE: The bucket must be in place and securely
seated for the dehumidifier to operate.
Always make sure the water bucket is locked into place on the dehumidifier.
Water Level
The dehumidifier will turn off automatically
when the bucket is full, or when the bucket is
removed or not replaced in the proper position.
The bucket must be replaced in the proper position for
the dehumidifier to work. The light will be on and the
dehumidifier will not run if the bucket is not in the
proper position.
