- Place the unit upright on a firm, level surface in the desired location. Ensure there is at least 8 inches (20 cm) of space around the unit for proper airflow.

4.3 Drainage Options
Your dehumidifier offers two drainage methods:
- Manual Drainage (Water Tank): The unit collects water in the internal tank. When the tank is full, the unit will automatically shut off and indicate that the tank needs emptying.
- Continuous Drainage (Drain Hose): For extended operation without manual emptying, attach the included drain hose to the continuous drainage port on the back of the unit. Route the hose to a suitable drain (e.g., floor drain, sink) ensuring it is sloped downwards to allow gravity drainage.

5. Operating Instructions
5.1 Control Panel
The intuitive control panel allows you to manage all functions of the dehumidifier.

- Power Button: Turns the unit ON or OFF.

5.2 Operating Modes
Select the appropriate mode for your needs:

- DEHU Mode (Dehumidify): In this mode, you can set a target humidity level between 30% and 80%. The unit will operate until the desired humidity is reached, then cycle on and off to maintain it.
- DRY Mode (Clothes Drying): This mode is designed to quickly dry clothes by running the dehumidifier continuously at a high fan speed.
- CONT Mode (Continuous): The unit will run continuously regardless of the ambient humidity level. This is ideal for very damp environments or when using continuous drainage.
5.3 Setting Target Humidity
In DEHU mode, press the HUMI button to adjust the desired humidity level. Each press will cycle through the available percentages (30% to 80%). The unit will automatically turn off when the set humidity is reached and restart when the humidity rises above the set level.

5.4 Timer Function
Press the Timer button to set a delay for the unit to turn ON or OFF. You can set the timer from 1 to 24 hours. For example, if the unit is OFF, setting a 2-hour timer will turn it ON after 2 hours. If the unit is ON, setting a 2-hour timer will turn it OFF after 2 hours.
5.5 Child Lock
To prevent accidental changes to settings, press and hold the Lock button for 3 seconds. The child lock indicator will illuminate. Repeat the action to deactivate the child lock.
5.6 Auto Defrost Function
The dehumidifier is equipped with an auto defrost function. If frost builds up on the evaporator coils, the unit will automatically enter defrost mode to melt the ice. This ensures efficient operation even in lower temperatures.

6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your dehumidifier.

6.1 Emptying the Water Tank
When the water tank is full, the unit will stop operating, and the 'Water Full' indicator will light up. Carefully pull out the water tank from the front of the unit, empty the collected water, and then slide the tank back into place until it clicks securely. The unit will resume operation.
6.2 Cleaning the Air Filter
The air filter should be cleaned every two weeks or more frequently depending on usage and air quality. A dirty filter can reduce efficiency and airflow.
- Turn off the dehumidifier and unplug it from the power outlet.
- Remove the air filter from the back or side of the unit (refer to the diagram in the product overview if needed).
- Wash the filter with clean water (not hotter than 104°F / 40°C) and a mild detergent.
- Rinse thoroughly and allow the filter to air dry completely before reinstalling. Do not expose to direct sunlight.
- Reinsert the dry filter into the unit.
6.3 General Cleaning
Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals, abrasives, or solvents, as these can damage the surface.
