Explanation
• Have you made a mistake in timer operation?
• Has the fuse blown or has the circuit breaker been
tripped?
• Is the power Switch at Off?
• Is the unit at the starting of Heating Operation?
If yes, Hot-start is activating.
• Is the unit in the Deicing?
If yes, wait for finishing the Deicing.
• Check that this is not a damp smell exuded by the
walls, carpet, furniture, or cloth items in the room.
• Condensation occurs when the airflow from the air
conditioner cools the warm room air.
• This is the Protection device of the air conditioner .
• Wait about three minutes and operation will begin.
• If the airflow begins before its temperature
become warm, it will cause an undesired
cooling effect. In order to prevent this, the
airflow will not begin until it is sufficiently warm.
• Is the air filter dirty? See air filter cleaning
instructions.
• The room may have been very hot when the room
air conditioner was first turned on. Allow time for it
to cool down.
• Has the temperature been set incorrectly?
• Are the indoor unit's air inlet or outlet vents
obstructed?
• For a noise that sounds like water flowing.
-This is the sound of freon flowing inside the air
conditioner unit.
• For a noise that sounds like the compressed air
releasing into atmosphere.
-This is the sound of the dehumidifying water being
processed inside the air conditioning unit.
• Are the batteries depleted?
