▼When cooling
Point the louver horizontally.
NOTE
• When stopped, the louver closes automatically.
• The louver automatically becomes horizontal or closed at the start of heating operation, defrosting operation, or when
the set temperature becomes the same as room temperature. If you set the swing or wind direction at this time, the
remote controller display will be the setting, but the louver will not move. When the normal heating operation that
blows warm air is started, the louver will be in the set wind direction.
• When the defrosting operation is performed during heating, the louver automatically closes to reduce the cold air
falling from the indoor unit.
• If the heating operation is performed less than 12 hours after the circuit breaker is turned on when the outside
temperature is low, the louver may automatically close immediately after the start of heating operation to reduce the
loss of cold air.
