TROUBLESHOOTING
The appliance does not emit cool air.
• Air is not circulating properly.
− Make sure that there are no curtains, blinds, or pieces of furniture blocking the front of the
appliance.
• The air filter is dirty.
− Clean the air filter once every 2 weeks.
− See "Cleaning the Air Filter" for more information.
• The room temperature is too high.
− In summer, cooling the indoor air fully may take some time. In this case, select the Jet mode to
cool the indoor air quickly.
• Cold air is escaping from the room.
− Make sure that no cold air is escaping through the ventilation points in the room.
• The desired temperature is higher than the current temperature.
− Set the desired temperature to a level lower than the current temperature.
• There is a heating source nearby.
− Avoid using heat generators like electric ovens or gas hobs while the air conditioner is in operation.
• Fan mode is selected.
− During Fan mode, air blows from the appliance without cooling or heating the indoor air.
− Switch the operating mode to cooling operation.
The indoor unit is still operating even when the appliance has been turned off.
• The Auto Clean function is being operated.
− Allow the Auto Clean function to continue since it reduces any remaining moisture inside the indoor
unit. If you do not want this function, you can turn the indoor unit off.
The appliance does not emit warm air.
• When the Heating mode starts, the vane is almost closed, and no air comes out, even though the
outdoor unit is operating.
− This is normal. Please wait until the appliance has generated enough warm air to blow through the
indoor unit.
• The outdoor unit is in Defrosting mode.
− In Heating mode, ice and frost is built up on the coils when the outside temperature falls. The
Defrosting mode reduces a layer of frost on the coil, and it should finish in approximately 15
minutes.
