  4.  Place the unit upright and wait 1 hour before use.


When first using the dehumidifier, operate the unit continuously for 24 hours.

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 top grille into the room. It is normal for the surrounding air to become slightly warmer as the dehumidifier operates.

Automatic Defrost

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 will automatically restart and dehumidifying will resume.

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 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) or above 90°F (32°C). The coils can become covered with frost at temperatures below 41°F, which may reduce performance.
  • The suggested range of relative humidity is between 40% and 50%
  • Use the dehumidifier in cooking, laundry 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.

NOTE: The dehumidifier has casters 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.

Always make sure the water bucket is locked into place on the dehumidifier.

Removing Collected Water

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 hose if using the bucket to collect water. When the hose is connected, water will flow through it onto the floor instead of into the bucket.


  • 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 a garden water hose (not included).

  1. Remove the bucket from the front of the unit.
  2.  Open the drain cover on the side of the unit.
  3. Thread a garden hose (not supplied) onto the nozzle and ensure it is seated securely. Cut to length and lead it to the floor drain.
  4. Replace the bucket in the unit.
    NOTE: The bucket must be in place and securely seated for the dehumidifier to operate. The drain hose must run down from the dehumidifier to the floor drain.

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 empty indicator will blink and the dehumidifier will not run if the bucket is not in the proper position.

Bucket Operation

DO NOT remove the foam piece and magnet block in the bucket assembly. If removed the Dehumidifier will not work properly.


Turn off the dehumidifier and remove the plug from the wall outlet before cleaning.

Grille and Case

To clean the case: Use water and a mild detergent. Do not use bleach or abrasives.

Water Bucket

To clean: Every few weeks, clean the bucket to prevent growth of mold, mildew and bacteria. Partially fill the bucket with clean water and add a little mild detergent. Swish it around in the bucket, empty and rinse.
NOTE: Do not use a dishwasher to clean the water bucket.
To remove:
Remove the bucket and pour out any water.
To replace:
Slide the bucket into the dehumidifier.
NOTE: The bucket must be in place and securely seated for the dehumidifier to operate.

Air Filter

The air filter behind the rear grille should be checked and cleaned at least every 250 hours of operation or more often if necessary. After 250 hours of operation, the Filter indicator light will glow to remind you to clean the filter. Remove the filter and clean it. Replace the filter and press and hold the filter button for 3 seconds.

To remove: Remove the rear grille and the filter will be attached.

To clean: Clean the filter with warm, soapy water. Rinse and let the filter dry before replacing it.

CAUTION: DO NOT operate the dehumidifier without a filter because dirt and lint will clog the unit and reduce performance.

Problem Possible Cause What To Do
Dehumidifier does not start The dehumidifier is unplugged. Makes sure the dehumidifier’s plug is pushed completely into the outlet.
The fuse is blown/circuit breaker is tripped. Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
Dehumidifier has reached its set humidity level or bucket is full. The dehumidifier automatically turns off when either condition occurs. Change to a lower setting or empty the bucket and replace properly.
Bucket is not in the proper position. The bucket must be in place and securely seated for the dehumidifier to operate.
Power Failure. There is a protective time delay (up to 3 minutes) to prevent tripping of the compressor overload. For this reason, the unit may not start normal dehumidification for 3 minutes after it

turned back on.

Dehumidifier does not dry the air as it should Did not allow enough time to remove the moisture. When first installed, allow at least 24 hours to maintain the desired dryness.
Airflow is restricted. Make sure there are no curtains, blinds or furniture blocking the top or back of the dehumidifier. See the Choosing a Location section.
Dirty Filter See the Care and Cleaning section.
The Humidity Control may not be set low enough. For drier air, press the ź pad and set to a lower percent value (%) or at the Nonstop setting for maximum dehumidification.
Doors and windows may not be closed tightly. Check that all doors, windows and other openings are securely closed.
Clothes dryer may be blowing moisure-laden air into the room. Install the dehumidifier away from the dyer. The dryer should be vented to the outside.
Room temperature is too low. Moisture removal is best at higher room temperatures. Lower room temperatures will reduce the moisture removal rate. Models are designed to be operated at temperatures above 41°F (5°C).
Dehumidifier runs too much Area to be dehumidified is too large. The capacity of your dehumidifier may not be adequate.
Doors and windows are open. Close all doors and windows to the outside.
Frost appears on the coils Room temperature is below 41°F (5°C) Please operate unit at temperatures above 41 F (5 C). Frost will usually disappear within 60 minutes. Under certain

conditions, frost may appear on the coils of your dehumidifier at temperatures above 41°F (5°C). This is normal and frost will usually disappear within 60 minutes. See the Automatic Defrost section.

Fan noise Air is moving through the dehumidifier. This is normal.
Water on floor Hose connection may be loose. Check the hose connection. See the Removing Collected Water section.
Intended to use the bucket to collect water, but a hose was attached. Disconnect the hose if using a bucket to collect water. See the Removing Collected Water section.
Bucket Full LED light flashing and alarm sounds while drain hose is connected. Drain hose not tight on fitting. Check drain hose connection.
Drain hose is kinked. Ensure the drain hose is pointed straight down to the floor and is not kinked in anyway.
