This document provides operating instructions and maintenance guidelines for a range of Gree dehumidifier models, including GDNM10A4BK4AA, GDNM12A4BK4AA, GDNM14A4BK4AA, GDNM10A4BK4BA, GDNM12A4BK4BA, GDNM14A4BK4BA, GDNM10A4BK4CA, GDNM12A4BK4CA, and GDNM14A4BK4CA. The manual emphasizes the importance of reading all instructions thoroughly before installation and use to optimize the dehumidifier's operation.
The Gree dehumidifier is designed to remove excess moisture from the air, helping to create a more comfortable and healthier indoor environment. It operates by drawing in humid air, passing it over a cooling coil to condense the moisture, and then discharging drier air back into the room. The collected water is stored in a removable bucket or can be continuously drained using an external hose.
The device features a control panel with indicators for various operational states. A "Water full" indicator illuminates when the water collection bucket is full, prompting the user to empty it. A "Running" indicator shows when the unit is actively dehumidifying. Additionally, a "Defrost" indicator lights up when the ambient temperature is too low, causing the unit to automatically initiate a defrost cycle, or if the air filter becomes clogged.
Humidity control is managed via a knob on the control panel, allowing users to select a desired humidity level or set the unit to "Continuous" operation for constant dehumidification. The unit also incorporates a 3-minute delay protection device for the compressor, designed to prolong its working life by preventing immediate restarts after being turned off or after a power interruption.
Before first use, it is crucial to place the unit upright for at least two hours to allow the cooling agent to stabilize. The dehumidifier must always be used in an upright position. For operation, ensure the unit is connected to a power source of the correct voltage and frequency, and that the water tank is correctly positioned. If the "Water full" lamp illuminates upon initial startup, the tank should be removed and re-inserted. The humidity control knob can then be set to the desired level or to "Continuous" for ongoing operation. The unit will shut down when the knob is turned to the "OFF" position.
The manual strongly advises against using an extension cord with the unit and recommends connecting it directly to a dedicated socket. It also warns against unplugging the dehumidifier while it is working, as this could damage the electronic circuits. For optimal air circulation, it is important to maintain at least 500mm (20 inches) of air space around all sides of the unit and to avoid obstructing the inlet or outlet openings with objects or placing the unit too close to walls or curtains. The appliance is intended for normal domestic/household use and should not be installed in a laundry room.
For continuous drainage, a 14mm inner diameter hose (not supplied) can be connected to the drainage outlet. The tube stopper and soft cover should be removed from the drainage outlet and stored in the bucket. When using continuous drainage, the PVC hose must be placed below the drainage hole, and care should be taken to avoid uneven surfaces or kinking the hose to ensure proper water flow.
Regular maintenance is essential for the dehumidifier's efficiency and longevity. Before any cleaning, the unit must be turned off and unplugged from the outlet.
Exterior Surfaces: The exterior surfaces of the unit should be cleaned with a damp sponge and dried with a clean, soft cloth. Harsh chemicals, alcohol, or products containing solvents should not be used. The unit should never be immersed in water.
Air Filters: The air filters, located inside the unit, collect dust and debris. To maintain efficiency, the air filters should be cleaned every two weeks, or more frequently if the unit operates in a dusty environment. Clogged filters can reduce dehumidifying efficiency and may cause the defrost lamp to illuminate. To remove the filter, tilt the dehumidifier backward, then pull the filter downward and forward. Filters can be cleaned with a vacuum cleaner. If very dirty, they can be washed in warm water (avoiding hot or soapy water) and must be completely dry before being reinstalled. Bending the filters should be avoided.
Healthy Filter (if applicable): The manual also describes the installation and maintenance of a "healthy filter." To install, remove the water tank, tilt the dehumidifier backward, and pull out the main filter. The healthy filter is then inserted into a specific groove and buttoned up before the main filter is reinstalled. When cleaning the healthy filter, specific instructions apply: silver ion filters should not be cleaned with water, while active carbon, photocatalyst, low temperature conversion (LTC) catalyst, formaldehyde eliminator, catechin, or mite-killing filters can be cleaned but without brushes or hard objects. These filters should be dried in the shade or sun, not by wiping. The healthy filter typically has a usage lifetime of one year under normal conditions, and a silver ion filter is considered invalid if its surface turns black (green).
Long-Term Storage: For seasonal storage or extended periods of non-use, the following steps are recommended:
The manual also includes a troubleshooting section to help users identify and resolve common issues, such as the unit not operating, the "Running" lamp twinkling, the dehumidifying function not working, or unusual noise during operation. It clarifies that some symptoms, like increased operation noise when the compressor activates or a musty odor when the unit is first used, do not indicate a breakdown. For issues that cannot be resolved, users are advised to contact authorized service centers.
