The following phenomena do not indicate unit failure.
FrostWash Operation
Noise occurred
during
FrostWash
operation
FrostWash Operation
does not start
Within 60 minutes after the end of "
FrostWash
", "
FrostWash
" is not operated for
product protection.
It is the sound that the internal machine is inflated and contracted by the
temperature change and the fin of the heat exchanger is frozen and thawed
Repeat for 1 se
cond
on and 1 second off for 10 seconds
Because "
FrostWash
" can not work when operating the "
FrostWash
" with remote
controller.
The air conditioner is operating
Outside air temperature, room temperature and room humidity are not
suitable for "
FrostWash
"
It has not been over 60 minutes since the end of "
FrostWash
"
Repeat for 4 seconds on and 1 second off for 15 seconds
Because
FrostWash has not been done for a long time
.
Operate the remote controller to operate "
FrostWash
".

It does not wash when outside temperature is less than about 1 degrees Celsius or
more than 43 degrees Celsius.
It does not wash when the humidity in the room is about 30% or less or about 70% or
more.
When "
FrostWash
" is done by operating a remote controller, it does not wash
when the room temperature is less than about 10 degrees Celsius or more than
about
32 degrees Celsius.

<Operation start>
The unit is preparing to blow warm air. Please wait.
<In operation>
The outdoor unit is defrosting. Please wait.
During heating, the operation
indicator blinks and air blow stops
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.
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.
Perking noise
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.
The outdoor unit continues to operate
even if operation is stopped.
Defrosting is underway (as the heating operation is stopped, the microcomputer
checks frost accumulated in the outdoor 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.
The OPERATION lamp is flashing.
Does not reach the temperature
setting
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.
