Owner’s Manual
IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
■ Use this appliance only for its intended
purpose as described in this Owner’s
Manual.
■ This dehumidifier must be properly
installed and grounded as described
in this manual before it is used.
■ Never operate this dehumidifier in an area
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. Do not use a cord that shows
cracks or abrasion damage along its length
or at either the plug or connector end.
■ Turn the dehumidifier OFF and unplug it
before making any repairs or cleaning.
■ GE does not support any servicing of
the dehumidifier. We strongly recommend
that you do not attempt to service the
dehumidifier yourself.
■ 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.
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.
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.

WARNING!
For your safety, the information in this manual must be followed to minimize the risk of fire, electric shock
or personal injury.

Consumer SupportTroubleshooting TipsOperating InstructionsSafety Instructions Care and Cleaning
Because of potential safety hazards under
certain conditions, we strongly recommend
against the use of an adapter plug.
However, if you must use an adapter,
where local codes permit, a temporary
connection may be made to a properly
grounded 2-prong wall outlet by use of
a UL-listed adapter available at most
local hardware stores.
The larger slot in the adapter must be
aligned with the larger slot in the wall
outlet to provide proper polarity in the
connection of the power cord.
When disconnecting the power cord from
the adapter, always hold the adapter in place
with one hand while pulling the power cord
plug with the other hand. If this is not done,
the adapter ground terminal is very likely to
break with repeated use.
If the adapter ground terminal breaks,
DO NOT USE the dehumidifier until a proper
ground has been established.
Attaching the adapter ground terminal to a wall
outlet cover screw does not ground the appliance
unless the cover screw is metal, not insulated, and
the wall outlet is grounded through the house wiring.
You should have the circuit checked by a qualified
electrician to make sure the outlet is properly
grounded.
USE OF ADAPTER PLUGS
READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.

Because of potential safety hazards under
certain conditions, we strongly recommend
against the use of an extension cord.
However, if you must use an extension
cord, it is absolutely necessary that it be
a UL-listed, 14 gauge, 3-wire grounding
type appliance extension cord having a
grounding type plug and outlet and that
the electrical rating of the cord be
15 amperes (minimum) and 125 volts.

Using the dehumidifier. GEAppliances.com
When first using the dehumidifier, operate the unit continuously 24 hours.
Choosing a Location
Automatic Defrost
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.
■ 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 65°F (18°C). The coils
can become covered with frost at temperatures
below 65°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
the bucket into 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.
There are 3 ways to remove collected water:
Use the bucket. When the bucket is removed,
the unit will shut off. Empty and replace the
bucket.
Use a hose. Water can be automatically
emptied into a floor drain by attaching a
water hose (not included) to the bucket hose
nozzle. Using a drill, make a hole at the end
of the nozzle located on the lower left side of
the bucket. Attach a water hose to the bucket
nozzle. Fasten by hand only.
Use a floor drain. The unit can also be placed
over a floor drain. Using a drill, make a hole
at the end of the nozzle located on the lower
left side of the bucket.
NOTE: The nozzle cannot be fixed after puncture. Use
an ordinary garden hose cap (not included) to reclose
if necessary.
NOTE: Avoid using mechanical tools to tighten the
water hose to the bucket nozzle. This may damage the
threads on the nozzle.
Always make sure the water bucket is locked into place on the dehumidifier.
Installing the Water Bucket
Lift the bucket and hook the slots on each side
onto the posts on the back of the dehumidifier.
The bucket should lock securely in place.
Make sure the bucket is locked securely in place
by pressing down on the upper back edge of the
bucket. It will be firmly seated when properly
installed.
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.

the other three tabs into their slots.
NOTE: Avoid using a dishwasher to clean the filter.
Cleaning the Coil
After removing the air filter, clean the coil
with a soft brush when the soil is soft and wet.
NOTE: Do not allow water to enter the
electrical/machine compartment through
the circular opening behind the coil.
Do not spray the coil with a hose.
Water Bucket
Every few weeks, rinse the inside of the water
bucket with a mild detergent to prevent growth
of mold, mildew and bacteria.
NOTE: Avoid using a dishwasher to clean the
water bucket.
