Explanation
This is to protect the air conditioner.
   You should wait for about 3 minutes.
■ A flowing sound:
   
This is the sound of refrigerant gas flowing in the air
   conditioner.
■ A 'psss' sound:
 
  ●
This is a sound emitted when the refrigerant flow stops
      or changes inside the unit.
■ A snap sound:
   
This is a sound produced when the indoor unit casing
      shrinks or expands slightly due to temperature
      changes.
■ A “plop-plop” sound:
   
This is a sound heard from the air conditioner when
   a ventilator is operated in a closed space. Open a
   window or stop the ventilator.
■ In COOL or DRY mode
   
Moisture in the air condenses into water on the cool
   surface of outdoor unit piping and drips.
This happens when the air in the room is cooled into
   mist by the cold air flow during cooling operation.
This happens when smells of the room, furniture, or
cigarettes are absorbed into the unit and discharged
with the air flow.
   (If this happens, we recommend you to have the indoor
unit washed by a technician.   Consult the service shop
where you bought the air conditioner.)
■ After operation is stopped:
  
The outdoor fan continues rotating for another 30
   seconds for system protection.
■ While the air conditioner is not in operation:
  
When the outdoor temperature is very high, the
   outdoor fan starts rotating for system protection.
For system protection, the air conditioner may stop
operating on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.
The following cases are not air conditioner troubles but have some reasons. You may just
continue using it.
