When the outdoor temperature is low and the humidity is high, frost may form on the outdoor unit. When heating operation starts, warm air does not blow from the indoor unit soon. During heating mode, the air conditioner stops before the set room temperature is reached. Airflow direction changes during operation or airflow direction cannot be set. ) During cooling mode, the vanes automatically move to the horizontal (down) position after 1 hour when the down (horizontal) airflow direction is selected. During heating mode, the vanes automatically move to the horizontal airflow direction when the airflow temperature is low or during defrosting mode. When the airflow direction is changed, the vanes move to the set position after detecting the base position. These sounds can be heard when refrigerant is flowing in the air conditioner or when the refrigerant flow is changing. These sounds can be heard when parts rub against each due to expansion and contraction from temperature changes. The indoor unit draws in air that contains gases produced from the walls, carpeting, and furniture as well as odors trapped in clothing, and then blows this air back into the room. If the indoor temperature and the humidity are high, this condition may occur when operation starts. During defrosting mode, cool airflow may blow down and appear like a mist. [. . . ] The indoor unit beeps to confirm that the signal transmitted from the IR wireless remote controller has been received. Signals can be received up to approximately 7 meters in a direct line from the indoor unit in an area 45° to the left and right of the unit. However, illumination such as fluorescent lights and strong light can affect the ability of the indoor unit to receive signals. If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be inspected. [. . . ]
