8.1 Symptoms that are NOT system
malfunctions
The following symptoms are NOT system malfunctions:
8.1.1 Symptom: A sound like water flowing is
heard
▪ This sound is caused by the refrigerant flowing in the unit.
▪ This sound may be generated when water is flowing away from
the unit during cooling or drying operation.
8.1.2

Symptom: A blowing sound is heard

This sound is generated when the direction of the refrigerant flow is
changed (e.g. when switching from cooling to heating).
8.1.3

Symptom: A ticking sound is heard

This sound is generated when the unit slightly expands or contracts
with changes in temperature.
8.1.4

Symptom: A whistling sound is heard

This sound is generated by the refrigerant flowing during defrost
operation.
8.1.5 Symptom: A clicking sound during
operation or idle time is heard
This sound is generated when the refrigerant control valves or
electrical parts operate.
8.1.6

Symptom: A clapping sound is heard

This sound is generated when an external device sucks air out of the
room (e.g. exhaust fan, extractor hood) while the doors and windows
in the room are closed. Open the doors or windows, or turn off the
device.
8.1.7 Symptom: White mist comes out of a unit
(Indoor unit, outdoor unit)
When the system is changed over to heating operation after defrost
operation. Moisture generated by defrost becomes steam and is
exhausted.
