Operating Instructions

Features

This section contains captioned illustrations of your appliance. Use the drawings to become familiar with
all parts and features and what they look like.

Electrical requirements

OBSERVE ALL LOCAL CODES AND ORDINANCES.
DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE
THE POWER SUPPLY CORD GROUND PRONG.

Electrical ground is required on this appliance.

A 115-volt 60 Hz, AC only, 15A fused and properly
grounded electrical supply is required. A time delay
fuse or time delay circuit breaker is recommended.
Use a dedicated circuit, serving only this appliance.
Do not use an extension cord.

Recommended grounding method

For your personal safety, this appliance must be grounded. This appliance has a power supply cord
with a 3-prong grounding plug. To minimize possible shock hazard, the cord must be plugged into a
mating grounding type wall receptacle, grounded in accordance with the National Electrical Code
(ANSI/NFPA 70) latest edition and all local codes and ordinances. If a mating wall receptacle is not
available, it is the personal responsibility and obligation of the customer to have a properly grounded
3-prong wall receptacle installed by a qualified electrician.

Operating your dehumidifier

Control

Your dehumidifier has a control panel containing an indicator and two controls — 

Auto Shut-Off, Fan Speed, and Humidity Control.

Auto Shut-Off ---This lamp glows when the bucket is full or missing.

Fan Speed --- This controls the speed of the airflow.

Humidity Control--- This controls the moisture in the room.

Unit operation

1.

Turn the Humidity Control to Off. Plug the power supply cord into an electrical outlet. 

2.

The Humidity Control can be set anywhere between Off and Max for normal operation.

If you need more dehumidification, turn the Humidity Control toward Max. If you need less
dehumidification, turn the Humidity Control toward Off.

3.

Turn the Humidity Control to Off to stop the unit manually.

4.

If you want to control the speed of air flow, turn the Fan Speed toward Low or High.

NOTE: The compressor will not operate for about two minutes to protect the compressor when

you turn the unit off and immediately back on.

De-icer control (invisible)

The Defrost Control senses frost build-up on the evaporator coil and automatically shuts off the
compressor. The fan continues to run, drawing air across the coil, and melting the frost. When the coil is
defrosted, the compressor automatically restarts, and dehumidifying resumes.

NOTE: Do not operate the dehumidifier at temperature below 65°F (18°C.) If your dehumidifier runs when
the temperature and humidity conditions of room are low, frost can form on its evaporator coil. This
interferes with proper operation. Therefore, dehumidifying performance may be reduced.

Automatic shut off

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.

Disposing of collected water

1.

Empty the bucket manually.

When the bucket is full, pull out and
empty it into a large sink or tub and
then replace it properly.

NOTE: Do not overtighten the
hose when connecting it to the
bucket. Use a rubber washer and
tighten by hand firmly without
stripping the plastic threads.

NOTE:Be careful while taking out
the bucket as it can cause
damage. 

NOTE:Please do not shake
strongly when you carry the
bucket. It can cause to breakage
of the handle or bucket cover.
It is advisable to carry the bucket
by supporting it from the bottom.

2.

The bucket has a threaded hose
connection which can be left open.
Drill a 1/4" (6.4 mm) hole in the
center of the hose connection.
Once opened, the hose connection
will continually drain water from the
bucket. 

NOTE: The nozzle cannot be fixed
after puncture. Use an ordinary
garden hose cap to reclose if
necessary.

NOTE:When inserting the bucket
into the unit. lifting up the bottom
tip of the bucket lightly makes
insertion easily.

When being attached to the bucket
drain hose connection, be sure the
hose doesn’t kink or bend. It should
lie flat from the dehumidifier to the
drain.

NOTE: The hose attachment will
accept a standard garden hose
filling. You can attach a screw-on
cap to use the bucket without a
hose.

Attach a length of garden hose to the threaded bucket drain hose
connection to carry water to the drain.

Installation Instructions

Installing the dehumidifier properly

1.

Allow at least 12 inches of space on all sides of the unit for good

air circulation.

2.

Install your dehumidifier on a floor, table, or shelf. When installing

the dehumidifier on a table or shelf, make sure the table or shelf is
strong enough to support the weight of the dehumidifier with a full
bucket. Do not sit or stand on the dehumidifier.
NOTE: The height of a table or shelf might provide a better position

from which to handle the bucket and help prevent icing of the
coils due to colder air near the floor (such as in a basement.)

3.

Lift the bucket and place it in the dehumidifier, making sure the

slots on the bottom side of the bucket are positioned correctly.

4.

Rollers let you move the dehumidifier easily. 

The cleaning of bucket

1.

Pull out the bucket cover.

2.

Brush off the filth in the
bucket.

NOTE: Please push the leftside
of the cover after the two
Upsides are upward completely
when closing the cover.

3.

Close the cover.

NOTE: Clean the bucket by
wiping with brush and cloth
dampened in a mild detergent
solution.

Choosing the proper location for your dehumidifier

• Use the dehumidifier in a

basement to help prevent
moisture damage.

• Use the dehumidifier in

laundry drying, bathing, and
dishwashing areas which have
excessive moisture.

• Use the dehumidifier to

prevent moisture damage
anywhere books are stored.
