What to Check First

  1. Airflow can be adjusted by changing the direction of the air conditioner’s louvers. Pull the ventilation lever forward to ventilate indoor air from the air outside. Shutting it by pushing the lever will cause inside room ventilation to occur strictly by recirculating the air inside the room.
  2. The up/down and left/right automatic control function varies by model, so refer to the user manual. If you use a product without ventilation lever, open other windows of your house from time to time for ventilation.
  3. ※ When you open the ventilation lever to refresh the air in the room so not to get it stuffy, outdoor air may flow in to degrade cooling performance capability. Do not forget to close the ventilation lever before using the product.
