Mist emerges from indoor unit.
Condensation effect due to cooling process.

Water flowing sound during operation.
Refrigerant flow inside the unit.

The room has a peculiar odour.
his may be due to damp smell emitted by the wall, carpet, furniture or clothing.

Indoor fan stops occasionally during automatic fan speed setting.
This helps to remove the surrounding odour.
