• Make sure that there are no curtains, blinds, or
pieces of furniture blocking the front of the air
conditioner.
• Clean the air filter once every 2 weeks.
• See "Clean the Air Filter" for more information.
• In summer, cooling the indoor air fully may take
some time. In this case, select the Jet Mode to
cool the indoor air quickly.
• Make sure that no cold air is escaping through
the ventilation points in the room.
• Set the desired temperature to a level lower
than the current temperature.
• Avoid using heat generators like electric ovens
or gas burners while the air conditioner is in
operation.
• During Fan Mode, air blows from the air
conditioner without cooling or heating the
indoor air.
• Switch the operation mode to cooling operation.
• The cooling effect may not be sufficient.
• In some operation modes, you cannot adjust
the fan speed. Select an operation mode in
which you can adjust the fan speed.
• In some operation modes, you cannot adjust
the temperature. Select an operation mode in

• The Timer Function may have timed out, which
turns the unit off. Check the timer settings.
