3. Setup
3.1 Unpacking
Carefully remove the dehumidifier from its packaging. Inspect the unit for any signs of damage. Retain the packaging for future storage or transport.
3.2 Initial Placement and Waiting Period
Place the dehumidifier on a stable, level surface. Ensure there is at least 20 cm of space around the unit for proper air circulation. Important: If the unit has been transported horizontally or tilted, allow it to stand upright for a minimum of 12 hours before plugging it into a power outlet. This allows the refrigerant to settle, preventing potential damage to the compressor.
3.3 Power Connection
Plug the power cord into a grounded electrical outlet. Ensure the outlet meets the power requirements of the unit.
3.4 Water Tank Installation / Continuous Drainage
The water tank should be correctly inserted into the unit. For continuous operation without needing to empty the tank, connect a suitable hose (not included) to the continuous drainage outlet. Ensure the hose is routed downwards to allow gravity drainage into a floor drain or larger container.

4. Operating Instructions
The control panel allows you to manage the dehumidifier's functions. Familiarize yourself with the buttons and indicators.

4.1 Power On/Off
- Press the On/Off button to turn the unit on or off.
- The unit features an automatic restart function, resuming its last settings after a power interruption.
4.2 Mode Selection
- Press the Mode button to cycle through available operating modes (e.g., automatic dehumidification, continuous dehumidification, laundry drying).
4.3 Fan Speed Adjustment
- Use the Speed button to select between low and high fan speeds. Higher speeds result in faster dehumidification but may produce more noise.
4.4 Setting Target Humidity
- Use the + and - buttons to set your desired relative humidity level. The unit will operate until this level is reached, then cycle on and off to maintain it.
4.5 Timer Function
- Press the Timer button to set an operating duration (e.g., 1-24 hours) after which the unit will automatically turn off.
5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your dehumidifier. Always unplug the unit before performing any maintenance.
5.1 Emptying the Water Tank
When the water tank is full, the unit will automatically stop operating and an indicator light will illuminate. Carefully remove the water tank, empty it, and reinsert it securely. The unit will resume operation.
5.2 Cleaning the Air Filter
The washable air filter should be cleaned regularly (e.g., every two weeks or as needed) to prevent dust buildup and maintain efficiency.
- Turn off and unplug the dehumidifier.
- Locate and remove the air filter from the unit (refer to Figure 5.1).
- Wash the filter with lukewarm water and a mild detergent. Rinse thoroughly.
- Allow the filter to air dry completely before reinserting it into the unit. Do not use a dryer or direct heat.

5.3 Cleaning the Unit Exterior
Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the surface.
5.4 Storage
If storing the unit for an extended period, ensure the water tank is empty and clean, and the air filter is clean and dry. Store the unit in an upright position in a dry, dust-free environment.
