4. 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 in the desired location. Ensure there is at least 20 cm (8 inches) of clear space around all sides for proper airflow. Do not place it against a wall or near heat sources.
- Power Connection: Plug the power cord into a grounded electrical outlet. Ensure the voltage matches the specifications of the unit.
- Initial Operation: Allow the unit to stand upright for at least 2 hours before plugging it in and turning it on, especially if it was transported on its side. This allows the refrigerant to settle.
5. Operating Instructions
5.1 Power On/Off
Press the Power button on the control panel to turn the dehumidifier ON or OFF.
5.2 Operating Modes
The dehumidifier offers various modes for different needs:

Figure 5.1: Visual representation of the dehumidifier's operating modes in different environments.
- Auto Mode: The unit automatically adjusts its operation based on the ambient humidity to maintain a comfortable level.
- Dry Mode (Clothes Drying): This mode is specifically designed to rapidly remove moisture from the air, assisting in drying clothes indoors.
- Fan Mode: The unit operates as a fan, circulating air without dehumidification.
5.3 Setting Humidity Level
Press the Setting button to cycle through desired humidity levels. The unit will operate until the set humidity is reached, then cycle on and off to maintain it.
5.4 Fan Speed Adjustment
Press the Speed button to switch between Low (LO) and High (HI) fan speeds.
5.5 Timer Function
Use the Timer button to set a delayed start or stop time for the dehumidifier, up to 24 hours.
5.6 Quiet Operation & Sleep Mode
The dehumidifier is designed for quiet operation, making it suitable for bedrooms and living spaces. In Sleep Mode (if available, typically activated via app or specific button combination), the fan speed is reduced, and display lights are dimmed for minimal disturbance.

Figure 5.2: The dehumidifier operates quietly, suitable for nighttime use in bedrooms.
5.7 Auto Defrost
The unit features an automatic defrost function. If frost builds up on the evaporator coils, the compressor will temporarily turn off, and the fan will continue to run until the frost melts. This ensures efficient operation in cooler environments.

6. Drainage Methods
The HINISO dehumidifier offers two methods for water drainage:
6.1 Manual Tank Drainage
When the 2.5-liter water tank is full, the unit will automatically shut off, and the "Full" indicator light will illuminate. To empty the tank:
- Gently pull out the water tank from the back of the unit.
- Carefully empty the collected water.
- Slide the empty tank back into the unit until it clicks into place. The unit will resume operation.

6.2 Continuous Drainage
For continuous operation without needing to empty the tank, you can attach the included drain hose:
- Locate the continuous drainage outlet at the back of the unit.
- Remove the rubber stopper (if present).
- Connect one end of the drain hose to the outlet.
- Direct the other end of the hose to a suitable drain (e.g., floor drain, large bucket), ensuring it is sloped downwards for gravity drainage.
