• Ensure the water bucket is positioned correctly for proper operation.

Note: Be careful when moving the unit if the water bucket is full to avoid spills.

Removing Collected Water

There are three ways to remove collected water:

1. Use the Bucket

• Bucket Full Indicator: The "Full" indicator light illuminates when the bucket is full (unit may turn off). The digital display may show P2.
• Removal: Slowly pull out the bucket, gripping handles securely. Pull straight to avoid spilling. Do not place the bucket on uneven surfaces.
• Repositioning: Dispose of water and reposition the bucket. It must be securely seated for the unit to operate. The machine will restart once the bucket is correctly in place.

Notes:

• Do not touch internal parts when removing the bucket.
• Push the bucket gently all the way in.
• If the pump hose detaches (see Fig. 5), reinstall it before replacing the bucket (see Fig. 6).
• Dry any spilled water inside the unit.
• If the bucket is removed while the unit is ON, the compressor and fan turn off, the unit beeps 8 times, and the display shows Eb. The same occurs if the bucket is removed while the unit is OFF.

• [Figure 4]: Shows pouring water out of the bucket.

• [Figure 6]: Shows how to reinstall the pump hose properly.

2. Continuous Draining

Water can be automatically emptied into a floor drain using a water hose (ID ≥ 5/16", not included) with a female threaded end (ID: M = 1", not included). On some models, the female threaded end is included.

• Setup: Remove the plastic cover from the back drain outlet. Insert the drain hose through the outlet and lead it to a floor drain or suitable facility.
• Ensure the hose is secure, with no leaks, and the end is level or down for smooth water flow.
• Direct the hose toward the drain, ensuring no kinks.
• Select desired humidity setting and fan speed to start continuous draining.

Note: When continuous draining is not used, remove the drain hose and dry the outlet.

Diagram Description:

• [Figure 7]: Shows removing the plastic cover counter-clockwise.
• [Figure 8]: Shows the drain hose connected to the unit.

3. Pump Draining (on some models)

Water can be emptied into a floor drain using a pump drain hose (1/4" OD, supplied).

• Setup: Remove the continuous drain hose and install the plastic cover clockwise. Insert the pump drain hose into the pump drain hose outlet (at least 15mm) and lead it to a floor drain.
• Press the pump pad on the unit to activate pump operation. The pump starts working when the bucket is full.

Note: The pump may generate loud noise for 3-5 minutes initially; this is normal.

• Ensure the hose is secure and free of kinks.
• Place the end of the hose into the drain, ensuring it is level or down.
• Select desired humidity setting and fan speed to start pump draining.

Troubleshooting Pump Operation: If the pump operation light blinks, turn off and unplug the unit. Check the pump filter (see Fig. 10), ensure the pump drain hose is not blocked, empty the bucket, and reinstall the hose properly. If the error repeats, call for service.

Note: Do not use pump draining below 0°C (32°F) to prevent freezing. Empty the bucket weekly when using pump draining. Remove the pump drain hose when not in use.

Installation Instructions

Positioning the Unit

A dehumidifier in a basement requires adequate air circulation. (See Fig. 12)

• Location: Do not use outdoors. Intended for indoor residential use only. Place on a smooth, level floor strong enough to support the unit with a full bucket.
• Clearance: Allow at least 8 inches of air space on all sides for circulation, and at least 16 inches for the air outlet.
• Temperature: Operate in areas where the temperature will not fall below 41°F (5°C) to prevent coil frosting.
• Placement: Keep away from clothes dryers, heaters, or radiators. Use in enclosed areas to prevent moisture damage to valuables.
• Operation: Close all doors, windows, and other openings to the room for maximum effectiveness.

Diagram Description:

• [Figure 12]: Illustrates required clearance around the unit (8 inches on sides, 16 inches for air outlet).

Note on Casters: Casters are located at four points on the bottom of the unit and can move freely. Do not force casters over carpet or move the unit with water in the bucket, as it may tip over and spill water.

Care and Cleaning

Turn the dehumidifier off and disconnect the plug from the wall before cleaning.

1. Clean the Grill and Case

• Use water and a mild detergent. Do not use bleach or abrasives.
• Do not splash water directly onto the unit to avoid electrical shock or damage.
• Use a vacuum cleaner or brush to clean the air intake and outlet.

2. Clean the Bucket

• Every few weeks, clean the bucket thoroughly to prevent mold, mildew, and bacteria. Partially fill with clean water and mild detergent, swish, empty, and rinse.

Note: Do not use a dishwasher. The bucket must be securely seated for operation.

3. Clean the Air Filter

• Remove the filter every two weeks.
• To remove, pull the filter outwards (See Fig. 13).
• Wash the filter with clean water and dry it.
• Re-install the filter.

❗ CAUTION: Do not operate the dehumidifier without a filter, as dirt and lint can clog it and reduce performance.

Diagram Description:

• [Figure 13]: Shows how to remove the air filter.

4. When Not Using the Unit for Long Periods

• After turning off, wait one day before emptying the bucket.
• Clean the unit, water bucket, and air filter.
• Wrap the cord with the power cord buckle.
• Cover the unit with a plastic bag.
• Store the unit upright in a dry, well-ventilated place.
