Corrective Action
Immediately turn off the air conditioner and contact your
installing contractor.
Ensure the power cord is plugged into the outlet.
Replace the fuse or check if the circuit breaker has tripped.
Turn off the air conditioner when a power failure occurs. When
the power is restored, wait 3 minutes, and then turn on the air
conditioner.
Check if the circuit breaker has tripped.
Press the power button.
• Check to see that the batteries are inserted with the correct
terminals (+) and (-).
• Replace with new batteries.
Make sure that no curtains, blinds or furniture are blocking the
front of the air conditioner.
Clean the air filter once every 2 weeks. Refer to the "Air Filter -
Cleaning/Maintenance" section for additional information.
In the summer it may take additional time to cool indoor air.
In this case, select jet cool operation to cool the indoor air
quickly. Refer to "Jet Cool/Jet Heat Operation" for additional
information.
Ensure cold air is not escaping through ventilation points in the
room.
Set the desired temperature to a level lower than the current
temperature.
Avoid using a heat generator such as an electric oven or gas
burner while the air conditioner is in operation.
During air circulation operation, air blows from the air
conditione without cooling or heating the indoor air. Switch the
operation mode to cooling operation.
Air conditioner cooling capacity may not be sufficient to handle
hot weather.
