42 Indoor Unit
• Have you made a mistake in timer operation?
• Has the fuse blown or has the circuit breaker been tripped?
• 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 protector of the mechanism.
• Wait about three minutes and operation will begin.
• 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.
• This sound is generated by the expansion/ constriction of the front panel, etc.
due to changes of temperature.
• Are the batteries depleted?
• Are the batteries inserted in the opposite (+) and (-) directions?
• When the air conditioner reaches the desired temperature, the airflow rate
reduces in order to avoid generating cool airflow during heating, or to minimize
energy consumption and indoor humidity change during cooling.
- This symptom is normal.
• Is the suction panel completely closed?
Close the suction grille completely.
• Is the water completely dried after cleaning PM1.0 filter?
If moisture remains, let it dry in the shade for about a day.
