NOTE: When the bucket is full or removed, the controls cannot be set.
1 Power Pad
Press to turn the dehumidifier on and off.
2 Filter Timer
After 250 hours of operation, the Clean the Filter indicator light will glow to remind you to clean the filter. Remove the filter and clean it. Press to turn off the Clean the Filter light. See the Care and Cleaning section.
3 Humidity Set Control Pads
The humidity level can be set within a range of 35% RH (Relative Humidity) to 80% RH (Relative Humidity) in 5% increments or at CO for continuous operation. To set the unit for continuous operation, press the
pad until the screen reads CO.
NOTE: If CO (Continuous) is selected, the dehumidifier will operate continuously at its maximum dehumidification settings if attached to a hose to drain or until the bucket is full.
For drier air, press the
pad and set to a lower percent value (%).
For damper air, press the
pad and set to a higher percent value (%).
When you first use the dehumidifier, set the humidity control to 45% or 50%. Allow at least 24 hours for the dehumidifier to achieve the humidity level. If you still have damper air than desired, set the humidity level to a lower setting or select Continuous for maximum dehumidification.
4 Display
Shows the set % humidity level while setting, then shows the actual (+/– 5% accuracy) room % humidity level.
5 Fan Speed Pad
Controls the fan speed. Press to select either High, Medium or Low fan speed. Set the fan control to High for maximum moisture removal. When the humidity has been reduced and quiet operation is preferred, set the fan control to Medium or Low.
6 Delay Off
While the dehumidifier is in operation, press this pad to set it to automatically turn off in 2 hours or 4 hours.
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.
Alarm
If the bucket is full or missing for more than 3 minutes, an alarm will sound for about 10 seconds to remind you to empty and replace the bucket.
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. NOTE: Fan will continue to run approximately 3 minutes after bucket is removed.
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 restart, in the settings last used, after the power is restored.
When first using the dehumidifier, operate the unit continuously for 24 hours.
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.
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.
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.
Always make sure the water bucket is locked into place on the dehumidifier.
There are 2 ways to remove collected water:
1 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.
NOTES:
2 Use a hose. Water can be automatically emptied into a floor drain by attaching a garden water hose (not included).

NOTE: The bucket must be in place and securely seated for the dehumidifier to operate.
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 off the dehumidifier 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.
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 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.

The air filter behind the front grille should be checked and cleaned at least every 250 hours of operation or more often if necessary.
After 250 hours of operation, the Clean the Filter indicator light will glow to remind you to clean the filter. Remove the filter and clean it. Replace the filter and press the Filter Timer pad to turn off the Clean the Filter light.
To remove:
Remove the bucket. Grasp the filter edge, and pull it straight down and out.
To clean:
Clean the filter with warm, soapy water. Rinse and let the filter dry before replacing it.
NOTE: DO NOT rinse or put the filter in an automatic 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.
