BUCKET FULL Light
Glows when the bucket is ready to be emptied, or when the bucket is removed or not replaced in the proper position.
Auto Shut Off
The Water Level Control Switch shuts off the dehumidifier when the bucket is full, or when the bucket is removed or not replaced in the proper position.
Auto 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.
Power Outage
In the case of a power outage or interruption, the unit will automatically re-start, in the settings last used, after the power is restored.
When first using the dehumidifier, operate the unit continuously 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 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.
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 (depending on model) 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.

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.
Removing Collected Water
There are 2 ways to remove collected water:




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.
Turn the dehumidifier off and remove the plug from the wall outlet before cleaning.
To clean the case:
Use water and a mild detergent. Do not use bleach or abrasives.
If cabinet paint chips, you can touch it up with a good grade enamel paint to prevent rust.
To clean the front grille:
Use a vacuum attachment or brush.
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 any water out.
To replace:
Slide the bucket into the dehumidifier.
NOTE: The bucket must be in place and securely seated for the dehumidifier to operate.

The air filter behind the front grille should be checked and cleaned at least every 30 days or more often if necessary.
NOTE: DO NOT rinse or put the filter in an automatic dishwasher.
To remove:
Grasp the filter edge and pull it out the side.
Clean the filter with warm, soapy water. Rinse and let the filter dry before replacing it. Do not clean the filter in a dishwasher.
CAUTION: DO NOT operate the dehumidifier without a filter because dirt and lint will clog it and reduce performance.

NOTE: Avoid using a dishwasher to clean the filter.
