Operating the Unit

Positioning the Unit

A dehumidifier operating in a basement may have little effect in drying an adjacent enclosed storage area (like a closet) unless there is adequate air circulation.

• Do not use outdoors. This dehumidifier is intended for indoor residential applications only and should not be used for commercial or industrial applications.
• Place the dehumidifier on a smooth, level floor strong enough to support the unit with a full bucket of water.
• Allow at least 20cm of air space on all sides of the unit for good air circulation.
• Place the unit in an area where the temperature will not fall below 5°C (41°F). Coils may frost up at temperatures below 5°C (41°F), reducing performance.
• Place the unit away from clothes dryers, heaters, or radiators.
• Use the unit to prevent moisture damage to books or valuables.
• Use the dehumidifier in a basement to help prevent moisture damage.
• The dehumidifier must be operated in an enclosed area to be most effective. Close all doors, windows, and other outside openings to the room.

Diagram (Fig.4a) shows placement clearances: 40cm or more above, 20cm or more on all sides (intake and outlet grilles).

Casters: Casters move freely. Do not force casters over carpet, nor move the unit with water in the bucket, as it may tip over and spill water.

When Using the Unit

• When first using the dehumidifier, operate it continuously for 24 hours.
• The unit is designed to operate in a working environment between 5°C (41°F) and 35°C (95°F).
• If the unit has been switched off and needs to be switched on again quickly, allow approximately three minutes for correct operation to resume.
• Do not connect the dehumidifier to a multiple socket outlet already used by other electrical appliances.
• Select a suitable location with easy access to an electrical outlet.
• Plug the unit into an electrical socket-outlet with earth connection.
• Ensure the water bucket is correctly fitted; otherwise, the unit will not operate properly.

NOTE: When the water in the bucket reaches a certain level, be careful when moving the machine to avoid it falling down.

Removing the Collected Water

There are two ways to remove collected water:

1. Use the bucket:

• When the unit is off and the bucket is full, the unit will beep 8 times, the Full indicator light will flash, and the digital display shows P2.
• When the unit is on and the bucket is full, the compressor and fan turn off after 30 seconds (for condenser drying). The unit will then beep 8 times, the Full indicator light will flash, and the digital display shows P2.
• Slowly pull out the bucket. Grip the left and right handles securely and pull straight out to avoid spilling water. Do not place the tank on the floor as the bottom is uneven, which could cause it to fall and spill water.
• Dispose water, and replace the bucket. The bucket must be in place and securely seated for the dehumidifier to operate.
• The machine will restart when the bucket is restored to its correct position.

NOTES:

• When removing the bucket, do not touch any parts inside the unit, as this may damage the product.
• Be sure to push the bucket gently all the way into the unit. Banging the bucket or failing to push it in securely may prevent operation.
• If there is some water in the unit when removing the bucket, dry it.

2. Continuous draining:

Water can be automatically emptied into a floor drain by attaching a water hose (not included).

• Cut down the cover from the back drain hose outlet. Attach a drain hose (ID=13.5mm) and lead it to the floor drain or a suitable drainage facility (see Fig.7).
• Ensure the hose is secure to prevent leaks.
• Direct the hose toward the drain, ensuring there are no kinks that would stop water flow.
• Place the end of the hose into the drain, ensuring it is level or sloping downwards to allow water to flow smoothly. Never let the hose point upwards.
• Select the desired humidity setting and fan speed for continuous draining to start.

NOTE: When the continuous drain feature is not being used, remove the drain hose from the outlet.

Diagrams (Fig.5, Fig.6, Fig.7) illustrate bucket removal and continuous draining setup.

Care and Maintenance

Turn the dehumidifier off and unplug it from the wall outlet before cleaning.

1. Clean the Grille and Case:

• Use water and a mild detergent. Do not use bleach or abrasives.
• Do not splash water directly onto the main unit, as this may cause electric shock, insulation deterioration, or unit rust.
• The air intake and outlet grilles get soiled easily; use a vacuum attachment or brush to clean them.

2. Clean the bucket:

Every few weeks, clean the bucket to prevent mold, mildew, and bacteria growth. Partially fill the bucket with clean water and a little mild detergent. Swish, empty, and rinse. NOTE: Do not use a dishwasher to clean the bucket. After cleaning, the bucket must be in place and securely seated for the dehumidifier to operate.

3. Clean the air filter:

The air filter behind the front grille should be checked and cleaned at least every 30 days, or more often if necessary. NOTE: DO NOT RINSE OR PUT THE FILTER IN AN AUTOMATIC DISHWASHER.

• To remove: Grip the tab on the filter and pull it upward, then pull it out (as shown in Fig.8).
• Clean the filter with warm, soapy water. Rinse and let the filter dry before replacing it. Do not clean the filter in a dishwasher.
• To attach: Insert the air filter into the unit from the underside upwards (See Fig.10).

CAUTION: DO NOT operate the dehumidifier without a filter, as dirt and lint will clog it and reduce performance.

Diagrams (Fig.8, Fig.9, Fig.10) show filter removal and attachment.

4. When not using the unit for long periods:

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