Location Requirements

WARNING: To reduce the risk of injury to persons, malfunction, or damage to the product or property when using this appliance, follow basic safety precautions, including the following:

• Do not locate outdoors. This dehumidifier is intended for indoor, residential use only. It is not recommended for commercial use.
• Allow at least 12 to 18 inches (30.5 cm to 45.7 cm) of space on the rear and sides of the dehumidifier for models with back louvers and above the dehumidifier for models with top louvers. A diagram illustrates this recommended spacing.
• You will need a surface strong enough to support the dehumidifier when its bucket is full of water.
• You will need a surface level enough to keep the water from spilling when the bucket is full of water.
• Do not block the louvers of the unit.
• Never operate this dehumidifier in an area that is likely to accumulate standing water. If this condition develops, for your safety, disconnect the power supply before stepping into the water.

Operation

Before turning on the dehumidifier, be sure that the bucket is empty and fits all the way into the dehumidifier. Humidity displayed is between 30% and 90% relative humidity. Humidity can be set between 30% and 80% relative humidity.

NOTE: In the event of a power failure, your dehumidifier will operate at the previous settings when the power is restored.

It's important to set the desired humidity level to an achievable setting. To ensure energy-efficient operation, only use the dehumidifier in a closed space, with no open windows or other sources of moist air (to avoid continuous running).

Operating temperature is between 38°F to 90°F (3.2°C to 32.2°C). At temperatures of 38°F (3.2°C) or less, water freezes inside the product. At temperatures over 90°F (32.2°C), the internal temperature of the product trips a protective device which deactivates the product to avoid product damage.

The compressor has a 3-minute delay before restarting. If the product is stopped and immediately restarted, to protect the compressor there is a 3-minute delay until the compressor restarts.

When the dehumidifier is operating, the indoor temperature will rise. The dehumidifier does not have a cooling/heating function. Heat is generated during operation, so the room temperature may be increased by about 6°F (3°C) depending on the usage conditions (indoor temperature, size of the room).

Using the Control Panel

A diagram shows the control panel with buttons for POWER, MODE, FAN, TIMER, and CLEAN FILTER, along with indicator lights and a digital display. Symbols for ENERGY STAR and WiFi are also visible.

POWER ON OR OFF ?

Press POWER to turn on or off the dehumidifier.

DESIRED HUMIDITY MODE ⚙️

Press and release MODE until you see the symbol for the desired humidity setting. Operating modes are Auto Dry, Continuous or Manual Set.

• AUTO DRY: The dehumidifier will operate in dry mode only. The fan speed is set automatically. The desired humidity is set to 50% automatically.
• CONTINUOUS O: The dehumidifier will operate continuously. The fan speed can be adjusted. The desired humidity cannot be adjusted.
• MANUAL SET O: The dehumidifier will operate at the selected fan speed to the set humidity level. If the humidity level of the room is higher than the desired humidity setting, the compressor will turn on. If the humidity level of the room is lower than the desired humidity setting, the compressor will turn off, as well as the fan.

NOTE: The de-icing function will turn off the compressor if a low temperature condition occurs. When the de-icer senses the correct operating temperature, the compressor will cycle back on. Some freezing is normal when dehumidifiers are used at low temperatures.

EMPTY BUCKET LIGHT ?

If this light is on, the fan and the compressor will stop running. This light indicates that you need to check:

• If the bucket is full, empty and re-install bucket. If the bucket is not in position, remove the bucket and re-install it. Make sure the bucket fits all the way into the dehumidifier and the bucket light is off, or dehumidifier will not run.

FAN SPEED ?

Press FAN to select fan speed.

• Choose LOW, HIGH or AUTO.
• LOW: Reach the desired humidity setting with lower sound level.
• HIGH: Will more quickly reach the desired humidity setting.
• AUTO: Achieves set humidity at normal speed.

NOTE: Once the relative humidity of the room hits the desired setting, the compressor will stop and the fan will be off periodically. The fan may periodically turn on, to read the humidity level, without the compressor running.

HUMIDITY LEVEL ➕➖

Press the Plus or Minus button to set the desired humidity level. Desired humidity in the digital display will flash for 5 seconds after operation. Actual room humidity will be displayed after 5 seconds of flashing the desired humidity.

1 Draining the Dehumidifier - Bucket Draining

If a floor drain is not available, or you do not plan to run your dehumidifier continuously, you may want to simply empty the bucket.

Unplug the product before removing the water bucket. If the bucket is removed while the product is operating, the compressor will stop.

A diagram shows the steps for removing and emptying the bucket:

• Grasp the bucket sides to slide out bucket (E).
• Lift the bucket (E) up by the handle (D).
• Pour water into a sink or tub.
• Fold down the handle (D) and reinstall the bucket (E).

WARNING: Sickness Hazard

Do not drink water collected in water bucket. Doing so can result in sickness.

2 Gravity Draining

If you plan to run your dehumidifier continuously, you can choose direct draining by attaching a garden hose to the unit. Please note that garden hose is not included.

Follow these steps for gravity draining:

• Turn off the dehumidifier and unplug the power supply cord.
• Unscrew the connector cover on the side of the unit.
• Remove bucket.
• Attach a garden hose (1) to the drain hose connector (2) on the inside of the dehumidifier. Securely attach the hose to be sure there is no water leak.
• Place the other end of garden hose into a floor drain. Check to see that the hose lies flat and is in the drain. Make sure all the parts of the hose are on a lower level than the hose connector on the dehumidifier. Also, the outlet of the hose should be at least 5.5 in. lower than the hose connector. The hose should not be kinked or pinched.
• Reinstall bucket.

Diagrams illustrate the hose attachment and the required drop in level for proper drainage.

NOTE:

• Garden hose sold separately.
• The drain hose inner diameter should be greater than 1/2 in.
• The connector is designed for North American garden hoses only.

IMPORTANT: In North America, the garden hose connectors are 3/4 in. diameter straight (non-tapered) thread with a pitch of 11.5 threads per inch (male part has an outer diameter of 1-1/16 in. (26.99 mm)).

NOTE: To use the bucket without the garden hose, simply remove the garden hose, then reinstall bucket. The bucket must be installed and properly aligned for the dehumidifier to operate with or without a garden hose connected.

3 Cleaning the Air Filter

The air filter is removable for easy cleaning. A clean filter helps remove dust, lint, and other particles from the air and is important for best operating efficiency. Check the filter every two weeks to see whether it needs cleaning.

• Turn off the dehumidifier.
• Remove the air filter (E).
• You may use a vacuum cleaner to clean the air filter. If the air filter is dirty, wash it in warm water with a mild detergent.
• NOTE: Do not wash air filter in the dishwasher or use any chemical cleaner. Air dry filter completely before reinstalling to ensure maximum operating efficiency.
• Reinstall the air filter.
• Turn on the dehumidifier.

A diagram shows the air filter removal process.

4 Cleaning the Exterior

Turn off the dehumidifier and unplug the power supply cord.

Dust the surface of the unit with a soft cloth or the dusting attachment of your vacuum cleaner.

5 Cleaning the Water Bucket

Every few weeks, rinse the inside of the water bucket with a mild detergent to avoid growth of mold, mildew and bacteria.

The dehumidifier's water bucket (2) has a water level float (1). Do not damage or remove the bucket's water level float. If the float is not properly in place, the Empty Bucket light will turn on, preventing operation, and could result in leaking.
