■
The f
ollo
wing phenomena do not indicate unit f
ailure
.
<Operation start>
The unit is preparing to blow warm air. Please wait.
<In operation>
The outdoor unit is defrosting. Please wait.
Hissing or fizzy sounds
Refrigerant flow noise in the pipe or valve sound generated when flow rate is
adjusted.
Squeaking
noise
Noise generated when the unit expands or contracts due to temperature changes.
Rustling noise
Noise generated with the indoor unit fan’s rpm changing such as operation start
times.
Clicking
noise
Noise of the motorized valve when the unit is switched on.
During heating, the operation indicator
blinks and air blow stops
– 36 –
Perking noise
Noise of the ventilation fan sucking in air present in the drain hose and blowing out
dehumidifying water that had accumulated in the condensed water collector. For
details, consult your sales agent.
Changing operation noise
Operation noise changes due to power variations according to room temperature
changes.
Mist
emission
Mist is generated as the air within the room is suddenly cooled by conditioned air.
Steam emitted from the outdoor unit
Water generated during defrosting operation evaporates and steam is emitted.
Odors
Caused as the smells and particles of smoke, food, cosmetics, etc. present in room
air become attached the unit and blown off into the room again.
Defrosting is underway (as the heating operation is stopped, the microcomputer
checks frost accumulated in the indoor unit and instructs the unit to perform
automatic defrosting if necessary).
Shows preheating or defrosting operation is underway.
As the protective circuit or preheat sensor operates when unit operation is stopped
during preheating and then restarted, or when operation mode is switched from
cooling to heating, the lamp continues to blink.
Actual room temperature may deviate slightly from the remote controller’s temperature
setting depending on the number of people in the room, indoor or outdoor conditions
when the air conditioner is used for more than one room at the same time.
