- This appliance uses R290 refrigerant, which is flammable. Handle with care and ensure proper ventilation.
Product Overview
Setup
- Unpacking: Carefully remove the dehumidifier from its packaging. Retain packaging for future storage or transport.
- Placement: Place the unit upright on a firm, level surface. Ensure there is at least 20 cm of space around the air inlet (rear) and outlet (front) for proper airflow. The unit is equipped with wheels and handles for easy movement. It is suitable for rooms up to 60 m³.
- Power Connection: Plug the power cord into a grounded electrical outlet that matches the voltage specified on the unit's rating label.
- Water Tank: Ensure the water tank is correctly inserted into the unit. For continuous drainage, refer to the 'Continuous Drainage' section.
Operating Instructions
The control panel is located on the top of the unit and features an LCD display and several buttons for easy operation.
Control Panel Functions:
- Power Button: Turns the unit ON or OFF.
- Humidity Setting Button (%): Allows you to set the desired humidity level between 30% and 80%. The unit will operate until this level is reached and then cycle on/off to maintain it. The LCD display shows the current room humidity.
- Mode Button (Water Droplets): Switches between Dehumidification and Ventilation modes.
- Timer Button (Clock Icon): Sets the operating timer for up to 12 hours.
Operating Modes:
- Dehumidification Mode: The compressor and fan operate to remove moisture from the air. The unit will automatically stop when the set humidity level is reached or the water tank is full.
- Ventilation Mode: The fan operates without the compressor, circulating air without removing moisture. This mode is automatically activated when the water tank is full.
Automatic Functions:
- Automatic Shut-off (Full Water Tank): When the 2.2-liter water tank is full, the compressor will automatically stop, and the unit will switch to ventilation mode. An audible signal will alert you. Empty the tank and reinsert it to resume dehumidification.
- Automatic Defrost: The unit features an automatic defrost function to prevent ice buildup on the evaporator coils, ensuring efficient operation in cooler environments (minimum operating temperature 5°C).
Continuous Drainage:
For extended operation without needing to empty the water tank, connect the included drainage hose. Locate the continuous drainage outlet on the back of the unit (refer to Figure 5). Attach the hose and direct the other end into a suitable drain, such as a floor drain, large bucket, or sink. Ensure the hose is positioned downwards to allow gravity to drain the water.
Maintenance
Emptying the Water Tank:
When the water tank is full, the unit will alert you and switch to ventilation mode. Carefully pull out the water tank, empty the collected water, and slide it back into place until it clicks securely. The unit will then resume normal operation.
Cleaning the Air Filter:
The dehumidifier is equipped with a washable antibacterial particulate filter. Regular cleaning is essential for optimal performance and air quality.
- Turn off and unplug the dehumidifier.
- Remove the air filter from its housing (typically located at the rear or side air intake).
- Clean the filter using a vacuum cleaner to remove dust and debris. For more thorough cleaning, wash it gently with lukewarm water and a mild detergent.
- Rinse the filter thoroughly and allow it to air dry completely before reinserting it into the unit. Do not use the unit without a dry filter.
Cleaning the Exterior:
Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface.
