2. Operating Modes
- Cooling Mode: Press the 'Mode' button until the 'Cool' indicator lights up. Use the '+' and '-' buttons to set your desired temperature.
- Fan Mode: Press the 'Mode' button until the 'Fan' indicator lights up. In this mode, the unit circulates air without cooling.
- Dehumidification Mode: Press the 'Mode' button until the 'Dry' indicator lights up. This mode helps reduce humidity in the room.

Care and Maintenance
1. Cleaning the Air Filter
Regular cleaning of the air filter is crucial for efficient operation. A dirty filter can reduce cooling capacity and increase energy consumption.
- Unplug the air conditioner from the power outlet.
- Locate and remove the air filter from the back of the unit.
- Wash the filter with warm, soapy water. Rinse thoroughly.
- Allow the filter to air dry completely before reinserting it into the unit.
- Clean the filter every two weeks or more frequently if the unit is used often.
2. Draining Water
During dehumidification or in very humid conditions, water will accumulate inside the unit. The unit has a self-evaporating system, but manual drainage may be required if the internal tank becomes full. Connect the drainage hose to the drainage outlet at the bottom rear of the unit and place the other end into a suitable container or floor drain.
3. Storage
Before storing the unit for an extended period, ensure it is completely drained of water and the filter is clean and dry. Store the unit upright in a cool, dry place, covered to protect it from dust.
