Troubleshooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.•
Indoor unit
The air conditioner stops
generating airfl ow during operation.
Once the set temperature is reached, the airfl ow rate is
•
reduced and operation stopped in order to avoid generat-
ing cool airfl ow (during heating) or in order to keep the
humidity from rising (during cooling). Operation will resume
automatically when the indoor temperature rises or falls.
Operation does not start soon.
When “ON/OFF” button was pressed soon
after operation was stopped.
When the mode was reselected.
This is to protect the air conditioner.•
You should wait for about 3 minutes.
The HEAT operation stops suddenly
and a fl owing sound is heard.
The outdoor unit is taking away the frost. The HEAT •
operation starts after the frost on the outdoor unit is
removed. You should wait for about 4 to 12 minutes.
The fl ap does not start swing
immediately.
The air conditioner is adjusting the fl ap position. The •
fl ap will start moving soon.
A sound is heard.
A sound like a fl ow of water
This sound is generated because the refrigerant in •
the air conditioner is fl owing.
This is a pumping sound of the water in the air condi-•
tioner and heard when the water is pumped out from
the air conditioner in cooling or drying operation.
The refrigerant fl ows in the air conditioner even if the •
air conditioner is not working when the indoor units in
other rooms are in operation.
Blowing sound
This sound is generated when the fl ow of the refriger-•
ant in the air conditioner is switched over.
Pinging sound
This sound is generated when the size of the air •
conditioner slightly expands or shrinks as a result of
temperature changes.
Clicking sound during operation or idle time
This sound is generated when the refrigerant control •
valves or the electrical parts operate.
Clopping sound
This sound is heard from the inside of the air condi-•
tioner when the exhaust fan is activated while the
room doors are closed. Open the window or turn off
the exhaust fan.
Outdoor unit
The outdoor unit emits water or steam.
In HEAT or RADIANT operation
The frost on the outdoor unit melts into water or steam when the air conditioner is •
in defrost operation.
In COOL or DRY operation
Moisture in the air condenses into water on the cool surface of outdoor unit piping •
and drips.
Radiant panel surface temperature
During RADIANT1 or RADIANT2 operation, the surface temperature of
•
the panel will be about 55°C at maximum; this is the normal condition.
