Operating conditions If the operation is continued under any conditions other than the following, the safety device may work to stop the operation. (Cooling/DRY) Cooling DRY Heating Hang a blind or a curtain on the window. This will enhance the cooling/heating effect by intercepting direct sunlight and drafts. A clogged air filter will reduce the cooling/heating effect, leading to waste of power. Clean the air filter monthly (every two weeks as required) or so. Outdoor temp.

Automatic operation In Automatic, the temperature setting and operation mode (DRY, Cooling or Heating) are automatically selected according to the room temperature and outdoor temperature at the time of starting operation. DRY operation In this mode, humidity is removed from the air. Note While running in the DRY mode, you may feel cool or warm air from the air outlet. In such case, readjust the airflow direction with the vertical airflow direction blades. (except Duct Connected type) 6 To adjust the temperature and airflow rate: Operation mode Setting to be adjusted Automatic Cooling Heating DRY Temperature cannot be adjusted. Temperature is adjustable. Recommended temperature Cooling : 26°C-28°C Heating : 20°C-22°C (Temperature) Five levels of airflow rate setting from " " to " " plus " " are available. (Airflow rate) Airflow rate cannot be adjusted. When the unit runs in the cooling or heating mode at a low airflow rate, the cooling or heating effect may be insufficient. To adjust the airflow direction: ( page 8) Heating operation Since the heating operation is performed by taking the heat from outdoor into the room, the heating capacity decreases as the outdoor temperature lowers. If the room is not heated sufficiently, it is recommended to use other heating appliance at the same time. Since the air conditioner heats the whole room by circulating hot air, it takes some time to heat the entire room completely.
