Parts

Display Screen and Controls

Pump Model

1. Power Button: Press to power the dehumidifier On or Off
2. Filter Button: After 250 hours of operation, the Filter indicator will illuminate to remind you to remove and clean the filter.
3. Humidity Control Buttons (-/+): The humidity level can be set in 5% increments from 35%-80% relative humidity. To activate nonstop operation, repeatedly press the pad until the screen reads "NS" The screen will read "NS" once you go below 35%.; Note about Nonstop mode: this option means that the dehumidifier will ignore the current humidity level and operate continuously. If you are using the drain bucket, the dehumidifier will stop operation once the bucket is full. If you are using the gravity drain or internal pump features, the unit will operate continuously.
4. Display Screen: When using the -/+ buttons, this screen will display the target humidity setting you choose. After a few seconds, the screen will revert to show the current humidity level in your room with 5% accuracy.
5. Fan Speed: Press to cycle through High, Medium, or Low fan modes. Higher fan speeds lead to increased moisture removal. When humidity has been reduced or quiet operation is preferred, set the fan to Medium or Low.
6. Timer: Delay off-while the dehumidifier is in operation, press the timer pad to have the unit power off later in 2 or 4 hours; Delay on while the dehumidifier is not in operation (but plugged in), press the timer pad to have the unit power on later in 2 or 4 hours.
7. Pump (Only available on select models): With the dehumidifier powered on and a 1/4 inch drain hose connected to the internal pump drainage joint, press and hold this button for 3 seconds to activate the internal pump mode. The Pump button on top of the unit will illuminate once this feature is activated; Note: If the Pump feature is powered on but there is no hose or drain plug inserted in the drainage joint, the unit will leak onto the floor.

Other Features

1. Full Indicator Light: Illuminates when the bucket is ready to be emptied or when the bucket is removed from the unit for an extended period. If the bucket is replaced incorrectly, the light will stay illuminated.
2. Alarm Sound: If the bucket is full or missing for more than 3 minutes an alarm will beep for 10 seconds to remind you to empty and/or replace the drain bucket.
3. Auto Shut Off: The unit will stop operation if the bucket is full or if the bucket is removed/ improperly installed.
4. Auto Defrost Mode: Through normal operation, frost may build on the evaporator coils. In this case, the compressor will power off while the fan stays running. You can usually tell if this is the case when the air exhaust emits cool air instead of warm air.
5. Power Outage Restart: In the event of a power outage or interruption, the unit will automatically revert to the last settings you choose before the power outage and restart operations.

Cleaning

Before cleaning, turn off the dehumidifier and disconnect the power cord from the power outlet. Do not spray or douse the dehumidifier with water, and do not use volatile liquids (e.g. gasoline, paint thinner, etc.) to clean the dehumidifier.

White Plastic Exterior: Wipe down the plastic areas by using a soft rag dipped in warm, soapy water. Do not use harsh chemicals (e.g. bleach) or abrasive pads.

Air Intake Grille: Use a dust catcher or vacuum nozzle attachment.

Water Bucket: Every few weeks you should clean the bucket to prevent the growth of bacteria, mold, and mildew. Partially fill the bucket with clean water and mild detergent and use a soft brush to scrub down the walls of the bucket. Do not use a dishwasher to clean the bucket as this may warp the plastic.

You will first need to remove the handle from the drain bucket.

Step 1: Remove the handle by aligning the two ends of the handle with the openings on the drain bucket lid.
