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 clopping 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 Hissing / Cracking sound

The sound of the Streamer discharge. It is not a malfunction.

8-1-8 A mechanical moving sound

• The sound made when the flaps, louvres, or front panel
correct their positions at the beginning or end of operation, or
while operation is stopped.
• It is the sound of the flaps, louvres, or front panel moving.

8-1-9 Symptom: White mist comes out of a unit

(Indoor unit, outdoor unit)

■In heating operation
When the system is changed over to heating operation after
defrost operation. Moisture generated by defrost becomes
steam and is exhausted.
■In cooling or drying operation
Moisture in the air condenses into water on the cool surface of
the outdoor unit piping and drips.

8-1-10 Symptom: The units can give off odours

• The indoor unit is blowing out room odours it has absorbed
(the smell of walls or carpeting, furniture, clothes, and so on).
If the air conditioner has been used for a long time, there is
a chance that a dirty heat exchanger or fan are emitting an
odour.
We recommend you to have the indoor unit cleaned. Please
consult your dealer. Do not spray the air conditioner unit with
any deodorisers.
• Due to Streamer discharge, the air outlet may emit a slight
odour as trace amounts of ozone are generated. However,
the amount is negligible and is not harmful to your health.
