emit cool air.
The appliance does not
emit warm 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.
The room may have been very hot when the room air conditioner was
first turned on.
• Allow time for it to cool down.
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 burners 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 a cooling operation.
Outside temperature is too high.
• The cooling effect may not be sufficient.
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.
Outside temperature is too low.
• The heating effect may not be sufficient.
