Standing the unit upright for 3-4 hours allows the refrigerant to move freely within the coils.

2. Run the unit continuously for 24 hours after letting the unit to stand upright for 3-4 hours. This allows the unit to work out any "kinks" that may have resulted during shipping from our factory or to your doorstep. o

Parts

Display Screen and Controls

1. Power Button

a. Press to power the dehumidifier On or Off

2. Filter Button

a. After 250 hours of operation the Filter indicator will illuminate to remind you to remove and clean the filter.

3. Humidity Control Buttons (-/+)

a. 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%.

b. 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

a. 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 within 5% accuracy.

5. Fan Speed

a. 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.

Choosing a Location

• Place the dehumidifier on a smooth and level floor strong enough to support the unit with a full bucket of water.
• Allow at least 18 inches of space on all sides of the unit for proper air circulation.
• Close all doors. windows. and other exterior openings of the room to improve the dehumidifying effect.
• Keep the air intake/exhaust clean and free of obstructions.
• Avoid placing the unit in direct sunlight or in areas where the temperature goes below 40°F or above 90°F.
• Humidity levels of 50-60% are optimal. Humidity levels above 60% may lead to mold or mildew growth.

Removing Collected Water

There are 3 options to remove water collected by your dehumidifier:

Option 1: Drain Bucket

Step 1: Grab both sides of drain bucket and remove from unit following the arrow below. Removing the bucket just after stopping operation may results in drips of water on floor.

Step 2: Empty the bucket by grasping the handle on top of the bucket with one hand. while supporting the bottom of the bucket with other hand.

Step 3: After emptying. replace the bucket in dehumidifier following the arrow direction below.

Option 2: Gravity Drain Hose

Note:
Water can be automatically emptied into a floor drain by attaching a drain hose with 3/4 " inner diameter (not included) which attaches to a male nozzle on the left side of the unit.

Step 1: Remove drain bucket from unit. Open drain cover door on right side of unit. Thread the 3/4" drain hose (not included) onto the nozzle. Replace drain bucket into the unit.

Step 2: Position the gravity drain hose into the floor drain or other water receptacle. Ensure that the gravity drain hose is directed downwards. If the drain hose is directed upwards or horizontally. water will not exit the drain hose and instead will collect in the drain bucket.

Option 3: Internal Pump

Not all models have an internal pump feature. Please check your model number or contact customer support if you are unsure.

The internal pump can pump water up to 15 feet in any direction: vertically or horizontally. Water will still collect in the drain bucket during operation. As the bucket starts to reach maximum capacity the pump will power on to remove water from the drain bucket.

If the pump feature is powered on and there is no drain plug or drainage hose in the drainage joint. water will leak from the drainage joint. If the pump feature is powered off while the unit is operating. water will not leak from the drainage joint. Please contact customer support if you have lost or misplaced your green drain plug.

Step 1: Depress the gray plastic area using your fingertip or a small. flat object.

Step 2: While depressing the gray plastic area. remove the green drain plug.

Step 3: Insert the included drain hose into the drainage joint.

Cleaning

Before cleaning. turn off the dehumidifier and disconnect power cord from 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 a 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

Step 2: Remove the drain bucket lid by depressing the four (4) buckles on the drain bucket.

Step 3: Remove the float from the drain lid.

Air Filter

After 250 hours of operation the Filter indicator light will illuminate on top of your dehumidifier. After cleaning the filter. place the Filter button again to reset the 250-hour timer. Do not forget to replace the filter before resuming operation. This may cause the evaporator coils to attract dust. which will harm the performance of your unit.

Clean the filter using war. soapy water. Rinse thoroughly and air dry completely.
Do not dry the air filter with a source of heat. such as a lighter or hair dryer. as this may damage the filter.

Filter access:
Remove the drain bucket. The Filter is a light white plastic tab near the bottom of the air intake grille. Pull the filter straight down to remove.
